Everything You Need to Know About the CSS will-change Property. Introduction If you’ve ever noticed “that flicker” in WebKit-based browsers while performing certain CSS operations, especially CSS transforms and animations, then you’ve most likely come across the term “hardware acceleration” before.
The CPU, GPU, and Hardware Acceleration In a nutshell, Hardware acceleration means that the Graphics Processing Unit (GPU) will assist your browser in rendering a page by doing some of the heavy lifting, instead of throwing it all onto the Central Processing Unit (CPU) to do. When a CSS operation is hardware-accelerated, it usually gets a speed boost as the page rendering gets faster. As their names show, both the CPU and the GPU are processing units. Btns.css - beautiful button styles. SVG `text` and Small, Scalable, Accessible Typographic Designs. Let's say you designed something with custom fonts that was a little bit fancy.
Perhaps a certain word is positioned between the ascenders of another word below it. Some text is kerned out below to match the width of that same word.

HTML ordered lists can be incremented in many different languages, but customizing the appearance of the leading numbers in each list item is rather difficult.
Formatting the list in an OpenType font and using font-feature-settings to produce a special numbers option is one possibility, but there is an easier method. By using the under-appreciated CSS counters property – usually associated with generating point-numbered lists – we can customize the leading numbers with abandon. Given a standard HTML ordered list: <h1>Clarke’s Three Laws</h1> <li>When a distinguished but elderly scientist states that something is possible, he is almost certainly right. <li>The only way of discovering the limits of the possible is to venture a little way past them into the impossible. <li>Any sufficiently advanced technology is indistinguishable from magic. Frosting Glass with CSS Filters. The following is a guest post by Bear Travis, a Web Standards Engineer at Adobe.
I'm a fan of how Adobe is pushing the web forward with new design capabilities, and doing it in a responsible way. CSS filters is a good example. They knew they were desired because Photoshop paved the way. They brought them to the web with a sensible syntax and they helped with both the spec and browser implementation. Now we're seeing them in stable browsers, and they are advocating use through responsible progressive enhancement. While filters such as contrast, saturate, and blur have existed in image editors for some time, delivering them on the web has historically required serving images with those filters already applied.

Demo The HTML. The Definitive Guide to CSS Transitions. Back in the golden days of the web, we had a little thing called Flash to help us make the web a dynamic, fun, interactive place.
But, Flash is being used less and less. Of course, in certain environments it can still be put to amazing use, but in today’s web environment you need CSS to get the job done. One of the easiest ways to give your site a near-instant facelift is to bring CSS3 transitions to the table (pun intended).

A lot of things were not intended in the first place like multi-column layouts, responsive web design and more; this is why it has become a language full of hacks and glitches, like some kind of odd steam machine with a bunch of extensions. On the bright side, this is what makes CSS fun (or kinda)! Photo credits Anyway, I’m not here to talk about my convictions but about CSS. Among others, I picked some really common yet annoying issues: Float clearing, an old battle I think this has to be the most common wat?
