Even if the browser ignores the closing slash in void tags, it's good practice to close it because: 1. in frameworks like react js if these are not close, it creates an error 2. if you want your document to be readable by an XML parser then must close all elements

Sanitizing iframes
```html
<iframe id="webpage"></iframe><br/> <button onclick="sanitize()">Sanitize</button>
<script> function sanitize() { // Create a sanitizer object with the default config const sanitizer = new Sanitizer(); // Find the iframe node const iframe = document.getElementById('webpage'); // Sanitize the iframe's document node const sanitizedFrameNodes = sanitizer.sanitize(iframe.contentWindow.document); iframe.replaceChildren(sanitizeFrameNodes); } </script>```

The setHTML() method of the Element interface is used to parse and sanitize a string of HTML and then insert it into the DOM as a subtree of the element. It should be used instead of Element.innerHTML for inserting untrusted strings of HTML into an element.
```js const unsanitized_string = "abc <script>alert(1)<" + "/script> def"; // Unsanitized string of HTML const sanitizer1 = new Sanitizer(); // Default sanitizer;
// Get the Element with id "target" and set it with the sanitized string. document.getElementById("target").setHTML(unsanitized_string, {sanitizer: sanitizer1});
// Result (as a string): "abc def" ```

If you're using JavaScript for writing to a HTML Attribute, look at the .setAttribute and [attribute] methods which will automatically HTML Attribute Encode. Those are Safe Sinks as long as the attribute name is hardcoded and innocuous, like id or class.
-
If you're using JavaScript for writing to HTML, look at the .textContent attribute as it is a Safe Sink and will automatically HTML Entity Encode.

And immediately after it, the 2 CSS downloads begin. What we want to do is move the CSS downloads to the left, so all rendering starts (and finishes!) sooner. So all you do it take the URLs of these two files and add them to .htaccess with H2PushResource in front. For me that means the URL to my custom theme's CSS /wp-content/themes/phpied2/style.css as well as some WordPress CSS stuff. While I was there I also added a JavaScript file which is loaded later. Why now start early? So the end result is:
WordPress tip to start loading some CSS and JS files earlier.
Sample code to add to
.htaccess:H2PushResource /wp-content/themes/phpied2/style.css H2PushResource /wp-includes/css/dist/block-library/style.min.css?ver=5.4.1 H2PushResource /wp-includes/js/wp-emoji-release.min.js?ver=5.4.1

The dataset read-only property of the HTMLElement interface provides read/write access to custom data attributes (data-*) on elements. It exposes a map of strings (DOMStringMap) with an entry for each data-* attribute.
```html
<div id="user" data-id="1234567890" data-user="johndoe" data-date-of-birth>John Doe</div>```
```js const el = document.querySelector('#user');
// el.id === 'user' // el.dataset.id === '1234567890' // el.dataset.user === 'johndoe' // el.dataset.dateOfBirth === ''
// set a data attribute el.dataset.dateOfBirth = '1960-10-03'; // Result on JS: el.dataset.dateOfBirth === '1960-10-03' // Result on HTML: <div id="user" data-id="1234567890" data-user="johndoe" data-date-of-birth="1960-10-03">John Doe</div>
delete el.dataset.dateOfBirth; // Result on JS: el.dataset.dateOfBirth === undefined // Result on HTML: <div id="user" data-id="1234567890" data-user="johndoe">John Doe</div>
if ('someDataAttr' in el.dataset === false) { el.dataset.someDataAttr = 'mydata'; // Result on JS: 'someDataAttr' in el.dataset === true // Result on HTML: <div id="user" data-id="1234567890" data-user="johndoe" data-some-data-attr="mydata">John Doe</div> } ```

function draw(x, y) { if (isDrawing) { c.beginPath(); c.arc(x, y, 10, 0, Math.PI*2); c.closePath(); c.fill(); } }
canvas.addEventListener('mousemove', event => draw(event.offsetX, event.offsetY) ); canvas.addEventListener('mousedown', () => isDrawing = true); canvas.addEventListener('mouseup', () => isDrawing = false);

Highlight part of an element This example uses the Range.setStart() and Range.setEnd() methods to add part of an address to a range. The selected range is then highlighted using Range.surroundContents(). The address contains nine nodes: five text nodes, and four <br> elements.
```html
Wyatt Earp<br> 101 E. Main St.<br> Dodge City, KS<br> 67801<br> USA
Nodes in the original address:
```
```js const address = document.getElementById('address'); const log = document.getElementById('log');
// Log info address.childNodes.forEach(node => { const li = document.createElement('li'); li.textContent =
${node.nodeName}, ${node.nodeValue}; log.appendChild(li); });// Highlight the street and city const startOffset = 2; // Start at third node: 101 E. Main St. const endOffset = 5; // End at fifth node: Dodge City, KS const range = document.createRange(); range.setStart(address, startOffset); range.setEnd(address, endOffset);
const mark = document.createElement('mark'); range.surroundContents(mark); ```

Following the newer definition, the aside element should be inside of the section element to which it is related. The main element is not a sectioning element (elements like article, section, body, figure etc. are). You can of course still place aside in main, but it will be related to the nearest sectioning element parent of main. That means there is no semantic difference (for aside) in these two examples:
```html
<body> <main></main> <aside></aside> </body> <body> <main> <aside></aside> </main> </body>```

Differences from innerHTML Element.innerHTML returns HTML, as its name indicates. Sometimes people use innerHTML to retrieve or write text inside an element, but textContent has better performance because its value is not parsed as HTML. Moreover, using textContent can prevent XSS attacks.
-
Differences from innerText Don't get confused by the differences between Node.textContent and HTMLElement.innerText. Although the names seem similar, there are important differences: textContent gets the content of all elements, including <script> and <style> elements. In contrast, innerText only shows "human-readable" elements. textContent returns every element in the node. In contrast, innerText is aware of styling and won't return the text of "hidden" elements. Moreover, since innerText takes CSS styles into account, reading the value of innerText triggers a reflow to ensure up-to-date computed styles. (Reflows can be computationally expensive, and thus should be avoided when possible.) Both textContent and innerText remove child nodes when altered, but altering innerText in Internet Explorer (version 11 and below) also permanently destroys all descendant text nodes. It is impossible to insert the nodes again into any other element or into the same element after doing so.

Summary of Attributes
-
about: Specifies the subject of a relationship. If not given, then the subject is the current document.
-
rel : Defines a relation between the subject and a URL given by either
hreforresource. The subject is either specified by the closest about or src attribute, @@ -
rev : The same as the the
relattribute, except that subject and object are reversed. -
property : Defines a relationship between the subject and either a string (if the
contentattribute is present) or a piece of markup otherwise (thecontentof the element that the property attribute is on). -
content : Specifies a string to use as an object for the
propertyattribute -
href : Specifies an object URI for the
revandrelattributes. <mark>Takes precedence over theresourceattribute</mark>. -
resource : Specifies an object URI for the
revandrelattributes ifhrefis not present. -
src : Specifies the subject of a relationship.
-
datatype : Specifies a datatype of the object of the
propertyattribute (either in thecontentattribute, or the content of the element that thedatattypeattribute is on.) By default, data in the content attribute is of typestring, and data in the content of an element has typexml:Literal. Ifdatatype=""is used, then for the RDF the element content is stripped of markup, and is of type string. -
typeof : Creates a blank node, which becomes the subject, and asserts that the current element contains relationships that match the given RDF type.

The simplest way to publish a description of your dataset is to publish DCAT metadata using RDFa. RDFa allows machine-readable metadata to be embedded in a webpage. This means that publishing your dataset metadata can be easily achieved by updating the HTML for your dataset homepage.
```html
<html prefix="dct: http://purl.org/dc/terms/ rdf: http://www.w3.org/1999/02/22-rdf-syntax-ns# dcat: http://www.w3.org/ns/dcat# foaf: http://xmlns.com/foaf/0.1/"> <head> <title>DCAT in RDFa</title> </head> <br /> <body> <div typeof="dcat:Dataset" resource="http://gov.example.org/dataset/finances">

First, here’s a magic trick you might not realize Hypothesis has up its sleeve. Consider this PLOS One article. Annotate it in one tab, then open a second tab and annotate the PDF version there. You’ll see both annotations in both tabs. How is that possible?
The answer is that when scholarly publishers provide HTML versions of articles, they typically include metadata that points to PDF versions of the same articles. Here’s one way that happens:
<meta name=”citation_pdf_url” content=”http://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0168597&type=printable”>Hypothesis remembers the correspondence between the HTML and PDF versions, and coalesces annotations across them.

4. Robustifying a link when linking to a specific version
If the main intent is to link to a specific state of an original resource, for example a snapshot of the original resource in a web archive or one of its version in a version control system, then Robust Link information is conveyed as follows:
hreffor the URI that provides the specific state i.e., the snapshot or resource version;data-originalurlfor the URI of the original resource;data-versiondatefor the datetime of the snapshot or resource version.
[...]
<a href="http://en.wikipedia.org/w/index.php?title=Web_archiving&oldid=485347845" data-originalurl="http://en.wikipedia.org/wiki/Web_archiving" data-versiondate="2012-03-20">Robust Link to this specific version of the Wikipedia page</a> -
3. Robustifying a link when linking to the original resource
If the main intent is to link to an original resource but also allow future users of that link to see the state of the original resource around the time the link was put in place, then Robust Link information is conveyed as follows:
hreffor the URI of the original resource for which the snapshot was taken;data-versionurlfor the URI of the snapshot;data-versiondatefor the datetime of linking, of taking the snapshot.
[...]
<a href="http://www.w3.org/" data-versionurl="https://archive.today/r7cov" data-versiondate="2015-01-21">Robust Link to the W3C home page</a> -
The approach proposed here is to convey this information on a link by leveraging HTML5's attribute extensibility mechanism. It introduces the following
data-attributes for the anchor (<a>) element:data-originalurlfor the URI of the original resource;data-versionurlfor the URI of the snapshot;data-versiondatefor the datetime of linking, of taking the snapshot.

although if you are using XMLDOM with JavaScript you can code something like var n1 = uXmlDoc.selectSingleNode("//bookstore/book[1]/title/@lang"); and n1.text will give you the value "eng"
- TEST, value: "selected".text

@KorayTugay, No, the first expression selects, doesn't "return" -- a set of nodes, and this set of nodes is not a string. A node is not a string -- a node is a node in a tree. An XML document is a tree of nodes. lang="eng" is just one of many textual representations of an attribute node that has a name "lang", doesn't belong to a namespace, and has a string value the string "eng" – Dimitre Novatchev Oct 22 '14 at
- OK: select, not value

//Parent[@id='1']/Children/child/@name will only output the name attribute of the 4 child nodes belonging to the Parent specified by its predicate [@id=1]. You'll then need to change the predicate to [@id=2] to get the set of child nodes for the next Parent. However, if you ignore the Parent node altogether and use: //child/@name you can select name attribute of all child nodes in one go.
- OK, select ALL
-
//Parent[@id='1']/Children/child/@name Your original child[@name] means an element child which has an attribute name. You want child/@name.
- OK: /@name
-
So far I have this XPath string: //Parent[@id='1']/Children/child[@name]
- [@name] NO SELECCIONA, sino que FILTRA!

Most of the metadata about our document lives in the head of the document, and it makes perfect sense. Most information about our bodies also live in our head.
Metadata placement.

Front end framework is a combination of two separate words, Front end + Framework. Front end is the visual site of any web application or a website, it is that part of the website with which a user interacts, note that backend is that part that involves API calls, database connectivity, authentication and so on, and a framework in literal sense means an essential supporting structure of an object, the object is a website in this case.
What's Front End Frameworks? Here's the complete guide to understand the best front end frameworks.

Th part of an URI after the # is called "fragment" and is by definition only available/processed on client side (see https://en.wikipedia.org/wiki/Fragment_identifier).
-
The main problem is that the browser won't even send a request with a fragment part. The fragment part is resolved right there in the browser. So it's reachable through JavaScript.

why do we have an <img> element? Why not an <icon> element? Or an <include> element? Why not a hyperlink with an include attribute, or some combination of rel values? Why an <img> element? Quite simply, because Marc Andreessen shipped one, and shipping code wins.That’s not to say that all shipping code wins; after all, Andrew and Intermedia and HyTime shipped code too. Code is necessary but not sufficient for success. And I certainly don’t mean to say that shipping code before a standard will produce the best solution.

However, as powerful as the <picture> element is, sometimes it gives us more power than is actually needed to achieve suitable responsiveness. Sometimes all it really takes is a regular <img> element using the srcset and sizes attributes inline.
-
-
-
That image only contains 200 pixels horizontally, but the browser stretches it to 400px wide or even farther!Luckily, you’ll see there’s an easy “fix” there at the end: our old good friend the width attribute!<img src="example.gif", srcset="example.gif 200w" sizes="(min-width: 400px) 400px, 100vw" width="200" /* <=== TA-DA! */ class="logo">As long as you can specify the width attribute so it reflects the true maximum size of your largest image, you won’t run into this problem of having sizes make your image wider than it naturally should go.
-
The selected source size affects the intrinsic size of the image (the image’s display size if no CSS styling is applied).
-
Of course in the world of responsive images, we put constraints on our images with CSS:img { max-width: 100%;}Now the image appears at it’s natural size unless it’s constrained by the parent container! Excellent.

The simple problem that I see with fragment identifiers is that their existence and functionality relies completely on the developer rather than the browser. Yes, the browser needs to read and interpret the identifier and identify the matching fragment. But if the developer doesn’t include any id attributes in the HTML of the page, then there will be no identifiable fragments. Do you see why this is a problem? Whether the developer has coded identifiers into the HTML has nothing to do with whether or not the page actually has fragments. Virtually every web page has fragments. In fact, sectioning content as defined in the HTML5 spec implies as much. Every element on the page that can contain content can theoretically be categorized as a “fragment”.
at the mercy of author
-
This means that, regardless of what the developer has done behind the scenes in the HTML, all HTML fragments on that page should be identifiable by external referrers.

There is a fundamental weakness in the name attribute, which the id attribute addresses: the name attribute is not required to be unique. This is OK for forms where you can have multiple elements with the same name, but unsuitable for the rest of the document where you are trying to uniquely identify an element.

HTML fragment identifiers, as defined in the registration for the text/html media type [RFC2854] operate on id attributes and (now less frequently) the name attribute of the a, applet, frame, iframe, img and map elements.

[gripe]Email is supposed to be a text-only medium. I can concede a need for rich text - the occasional bold or italic - but background pictures are just needless bloat.[/gripe]
-
Negative margins are in many cases equivalent to position:relative; with negative position, e.g. position:relative; top:-100px, as in Guffa's answer.
-
I used to pull stunts like this all the time as soon as tables came. Really ugly, and may seriously embarrass any validator you run it trough: overlapping table cells. Works in most browsers though and even without css.

Negative margins get removed by Gmail and others. So, no negative margins.
-
But in the dark world of HTML email, where the motto is "code like it's 1996" because Outlook uses the rendering engine from MS Word and Gmail removes almost everything, every method for making two elements overlap that I can think of is unsuitable due to poor client support

You can't use negative margin in html email. To mimic this, there are 2 ways to do it, the nested tables way and the more complex rowspan way:
-
gmail and other mail services are ignoring the negative margin.
-
-
-
You may have noticed your emails looking a little cramped in Hotmail and Outlook.com recently. The culprit? Discontinuation of support for the margin property in these email clients. Rather than honoring your carefully spaced paragraphs and images, Hotmail and Outlook.com are now completely stripping margin from paragraph tags, leaving default values (0 for the top, right and left; 1.35em for the bottom, to be exact) in their place.

Negative values are mostly unsupported in html email. So is CSS position. For webmail at least, this is so that your email doesn't render outside of the desired window. Imagine Gmail with your CSS or email affecting the interface - they've limited the CSS you can use specifically to prevent this.
-
Yeah, as many developers will tell you, designing/coding for email is an incredibly hit-or-miss proposition...this is simply one more thing that may work in some email clients. The only consistent behavior in HTML/CSS emails is that nothing is consistent. :-)

No, most css doesn't work in emails, stick to tables and images.

If you're trying to use flexbox as a responsive way to adapt your mails in different devices, well there's a framework for that called MJML hope it works for you.

HTML in emails is somehow in a forgotten world and is about lots of years behind us.

With every other change I make, I have to test in a dozen clients and make sure it looks fine. Why is there so much variation in email style implementation amongst different clients?
-
I'm coding an email for a project and man! it's such a pain. Every other client has it's own implementation and supported rules. Some don't allow even simple properties like background-image while some support most advanced rules like media queries
