Apply filters like blur, brightness, saturation and hue to images. Combined with CSS blend modes, you can create powerful image effects using only code. This can drastically reduce the amount of time spent back and forth between designers and developers.
This lesson covers flexbox in a reusable mixin that should cover most layout situations on your site. With variables and common defaults, this mixin will cover most alignment issues and replace the need for tables for all time. Need a column with each item evenly spaced but starting their alignment on the top? No problem! How about a row with the items evenly spaced out as well as equal spacing around the edges? We have you covered!
You can target an element that has no child elements by using the
:empty pseudo-class. With browser support down to IE9, it's solid, easy way to select empty elements without any additional markup.
Be aware that whitespace is considered a "child", so
:empty will not work if the element has no children, but has space between the opening and closing tags.
Learn how to use CSS columns to quickly lay out fluid columns that are responsive, degrade gracefully and don't require extra markup.
width. The browser will render as many columns as it can with the width provided. If each column can take up more than the value provided, they will do so.
column-spanenables a specific element to ignore
column-width. It can be set to an integer to span a certain number of columns, or "all" to span them all. However, this property does not work in Firefox. A workaround could be to move the element (say, a heading) outside of the container with the
columnsapplied to it. That way, it remains outside of the automatic column flow.
column-fillallows you to change the way content flows into columns. By default, it's set to "balance", where content is distributed as much as possible between columns. It can also be set to "auto", but in order to do so, it requires setting a fixed height. This breaks the idea of fluid, responsive layouts, so use it with caution. You'll also need some browser prefixes, so be sure to reference this browser support chart.
The Flexbox css spec allows for more adjustable layouts. The
flex-direction property allows you to easily change the layout on the children of an element without making any changes to the dom, which is particularly useful when combined with media queries.
Learn how to apply timing functions to CSS transitions. We'll talk about pre-defined functions like 'ease-in', 'ease-out' and 'step', and then look at how to specify a custom function capturing the exact transition effect you're looking for.
Learn how to use native CSS transitions to automagically add motion to your application. By specifying a simple transition rule, changes to the values of specific properties can be interpolated over time to give a graceful, polished look and feel to what used to be a jarring and sudden transition.
DOM hierarchy pseudo-classes allow you to style specific elements based on where they fall in the hierarchy and what type of elements they are. You can also use :nth-child to target custom element patterns, like every other element.
