    1. Validations allow us to set specific constraints or rules that determine what data users can enter into an input. When a user enters data that breaks the rules, a message will appear, providing feedback on what was wrong with the entered data and how to fix it.

      HTML forms have an internal validation mechanism.

    1. ✅ We can actually use a neat trick which basically consists in making a CSS grid with a single grid item. All we really have to do then, is taking our grid-template-rows and make it transition from 0fr to 1fr: this way, our grid item will transition from 0 to its "natural" height. It's THAT simple:

      ```css .accordion - body { display: grid; grid - template - rows: 0 fr; transition: 250 ms grid - template - rows ease; }

      .accordion: hover.accordion - body { grid - template - rows: 1 fr; }

      .accordion - body>div { overflow: hidden; } ```

    1. Las acciones que se pueden realizar dentro de un formulario son definidas como form controls. El número de acciones es bastante grande y vale la pena revisar todas las posibilidades.

    1. I’m sure you can imagine, the ability to shift an element around based on its regular position is pretty useful. I find myself using this to line up form elements many times that have a tendency to not want to line up how I want them to.
    1. I don't particularly recommend that you just use this in its unaltered state in your own projects. It should be tweaked, edited, extended, and otherwise tuned to match your specific reset baseline.

      Aún cuando se trata de un reseteo completo de estilo CSS, proponentes de este método como es the Meyer's Reset recomiendan sobreescribir partes del reseteo con las preferencias personales del diseñador. Esto quiere decir que un reseteo no debe ser un reseteo en blanco, sino un reseteo hacia el estándar o base que el diseñador prefiera.

    1. Hay una serie de buenas prácticas en la fabricación de tablas que permiten una interacción más eficiente entre el usuario y la data que se busca comunicar. Una buena experiencia entre el usuario y las tablas dentro de una página web dependen en suma del diseño establecido. La fabricación de buenas tablas en la web solo requieren de conocimientos de HTML y CSS.

    1. To give you some interesting examples, in the case of a long table you could make the table header and footer repeat on every printed page, and you could make the table body display on a single page and have the contents available by scrolling up and down.

      Las etiquetas <thead>, <tbody>, and <tfoot> proveen a las tablas HTML una fuerte capacidad de personalización a través de selectores CSS.

    1. Now, you can add <hr> (horizontal rule) elements into the list of select options and they will appear as separators to help visually break up the options
      <div itemscope itemtype="http://schema.org/Code"> ```html <label for="major-select">Please select a major:</label> <br/> <select name="majors" id="major-select"> <option value="">Select a major</option>
      <option value="arth">Art History</option> <option value="finearts">Fine Arts</option> <option value="gdes">Graphic Design</option> <option value="lit">Literature</option> <option value="music">Music</option>

    1. Did you know you can now use streaming promises in SvelteKit? No need to import anything - it just works out of the box

      Every property of an object returned by the load function can be a promise which itself can return an object that can have a promise as property, and so on.

      Can build a tree of promises based on data delivery priority.

    1. Security considerations When inserting HTML into a page by using insertAdjacentHTML(), be careful not to use user input that hasn't been escaped.

      ```html <select id="position"> <br /> <option>beforebegin</option>

      <option>afterbegin</option> <option>beforeend</option> <option>afterend</option>


      <button id="insert">Insert HTML</button> <button id="reset">Reset</button>

      Some text, with a code-formatted element inside it.


      ```js const insert = document.querySelector("#insert"); insert.addEventListener("click", () => { const subject = document.querySelector("#subject"); const positionSelect = document.querySelector("#position"); subject.insertAdjacentHTML( positionSelect.value, "inserted text" ); });

      const reset = document.querySelector("#reset"); reset.addEventListener("click", () => { document.location.reload(); });


    1. Use insertAdjacentHTML(). It works with all current browsers, even with IE11.

      js var mylist = document.getElementById('mylist'); mylist.insertAdjacentHTML('beforeend', '<li>third</li>');

    2. HTML 5 introduced the <template> element which can be used for this purpose (as now described in the WhatWG spec and MDN docs). A <template> element is used to declare fragments of HTML that can be utilized in scripts. The element is represented in the DOM as a HTMLTemplateElement which has a .content property of DocumentFragment type, to provide access to the template's contents. This means that you can convert an HTML string to DOM elements by setting the innerHTML of a <template> element, then reaching into the template's .content property.

      ```js /* * @param {String} HTML representing a single element * @return {Element} / function htmlToElement(html) { var template = document.createElement('template'); html = html.trim(); // Never return a text node of whitespace as the result template.innerHTML = html; return template.content.firstChild; }

      var td = htmlToElement('<td>foo</td>'), div = htmlToElement('<div><span>nested</span> <span>stuff</span></div>');

      /* * @param {String} HTML representing any number of sibling elements * @return {NodeList} / function htmlToElements(html) { var template = document.createElement('template'); template.innerHTML = html; return template.content.childNodes; }

      var rows = htmlToElements('<tr><td>foo</td></tr><tr><td>bar</td></tr>'); ```

    1. HTML templating and streaming response library for Worker Runtimes such as Cloudflare Workers.

      js function handleRequest(event: FetchEvent) { return new HTMLResponse(pageLayout('Hello World!', html` <h1>Hello World!</h1> ${async () => { const timeStamp = new Date( await fetch('https://time.api/now').then(r => r.text()) ); return html`<p>The current time is ${timeEl(timeStamp)}.</p>` }} `)); }

    1. ```js function makeDocument() { let frame = document.getElementById("theFrame");

      let doc = document.implementation.createHTMLDocument("New Document"); let p = doc.createElement("p"); p.textContent = "This is a new paragraph.";

      try { doc.body.appendChild(p); } catch (e) { console.log(e); }

      // Copy the new HTML document into the frame

      let destDocument = frame.contentDocument; let srcNode = doc.documentElement; let newNode = destDocument.importNode(srcNode, true);

      destDocument.replaceChild(newNode, destDocument.documentElement); } ```

    1. You can have multiple nested React.lazy components inside React.Suspense.


      const CatAvatar = React.lazy(() => import('./path/to/cat/avatar')); const ThorAvatar = React.lazy(() => import('./path/to/cat/thor-avatar'));

      const AppContainer = () => ( <React.Suspense fallback="loading..."> <CatAvatar /> <ThorAvatar /> </React.Suspense> ); ```

    1. CSS-generated content is not included in the DOM. Because of this, it will not be represented in the accessibility tree and certain assistive technology/browser combinations will not announce it. If the content conveys information that is critical to understanding the page's purpose, it is better to include it in the main document.
    1. Microdata DOM API

      Warning: Microdata were implemented in some browsers for a long time. Nowadays, they have been abandoned and removed from all browsers and are therefore deprecated. You can't use them anymore and this document is kept as information only.
