Auto Margins With auto margins, flex items can be centered, spaced away or packed into sub-groups. Unlike justify-content, which is applied to the flex container, auto margins go on flex items. They work by consuming all free space in the specified direction. Align group of flex items to the right, but first item to the left Scenario from the question: making a group of flex items align-right (justify-content: flex-end) but have the first item align left (justify-self: flex-start) Consider a header section with a group of nav items and a logo. With justify-self the logo could be aligned left while the nav items stay far right, and the whole thing adjusts smoothly ("flexes") to different screen sizes.

If you don't need to support IE9 or lower, you can use flexbox freely, and don't need to use floated layouts.

Honestly, even without flexbox support, most of the layout problems would be solved with simple-basic CSS3 support that is standard in all clients.

As a conclusion, I’d say that Flexbox in an email unfortunately causes more troubles than it helps solving.

Now that we’ve gotten newer layout features — again, like grid and flexbox — floats, too, have sort of fallen by the wayside, perhaps either because there are better ways to accomplish what they do

Just like in flexbox, this will move the displayed grid items out of source order, placing them after the grid items that don’t have explicit order values.

This nav bar by Chris Coyier is a great example of something that makes more sense as a flexbox than grid.

Flexbox and grid play well together, and are a huge step forward from the float & table hacks they replace.

Flexbox's strength is in its content-driven model. It doesn't need to know the content up-front. You can distribute items based on their content, allow boxes to wrap which is really handy for responsive design, you can even control the distribution of negative space separately to positive space.

Flexbox: content dictates layout

Grid: container dictates layout

Flexbox is for one dimensional layout (row or column). CSS grid is for two dimensional layout.

the difference is exactly like block and inline-block ... if you use inline-grid with sibling elements they will be placed in the same line unlike grid ... so here you change to grid also since each element is inside a grid area alone

Situation: you have a single line of text in a flex child element. You don’t want that text to wrap, you want it truncated with ellipsis (or fall back to just hiding the overflow). But the worst happens. The unthinkable! The layout breaks and forces the entire flex parent element too wide. Flexbox is supposed to be helping make layout easier!

Optional Downward Flexibility Management (ODFM

iron-list must either be explicitly sized, or delegate scrolling to an explicitly sized parent. By "explicitly sized", we mean it either has an explicit CSS height property set via a class or inline style, or else is sized by other layout means (e.g. the flex or fit classes).

This model is the most flexible and open-ended of the four; your goal as an instructor is not to design a full-fledged semester of material, activities, and assessments. Rather, your goal is to work with your class to design and become a learning community, working collaboratively and individually towards your determined learning goals. For this to work you should have: a set of possible/preferred learning objectives for your classa library of course materials, preferably with as much as possible in digital formata suggested list of digital tools and technologies that you’re comfortable from with a list of possible assignment/project/assessment ideas that are related to your learning objectivesa willingness to experiment and invite your students into the teaching & learning process. At the onset of class you will need to facilitate a conversation among you and your students about how the class will unfold. This can be done in small groups f2f, via an online communication tool, or in a hybrid mix of both. As a community you should plan on addressing the following: what are our objectives as a learning community? what kind of work could we engage in to meet these objectives? what physical/virtual spaces would we like to work in? how/when do we want to meet in these spaces?how do we want to measure (assess) if an objective has been met?what rules and policies should govern our work? how will we work virtually and respect everyone’s boundaries and personal situations? how will we work f2f and respect public health recommendations and personal situations? You will probably need to spend at least the first 1-2 weeks answering these questions together and then designing a plan for your course. Make sure you and your students talk through various complications: what if the university’s policies about meeting f2f change? what if classes are forced to move entirely virtual/remote? what someone (students or professor!) gets sick?

Most of my online students are also taking courses on campus, and they are taking some classes online as a way of balancing complicated college/work/life schedules
