Pocket Guide TypographyGo! Flexible CSS cover images I recently included the option to add a large cover image, like the one above, to my posts. The source image is cropped, and below specific maximum dimensions it’s displayed at a predetermined aspect ratio. This post describes the implementation. Demo: Flexible CSS cover images Known support: Chrome, Firefox, Safari, Opera, IE 9+ Features The way that the cover image scales, and changes aspect ratio, is illustrated in the following diagram. The cover image component must: render at a fixed aspect ratio, unless specific maximum dimensions are exceeded;support different aspect ratios;support max-height and max-width;support different background images;display the image to either fill, or be contained within the component;center the image.

CSS GuidelinesGo! WTF, HTML and CSS? VideoSWSGo! 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. 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. Old School: Frosted Glass with Images The frosted glass effect has been kicking around the internet for a while; we even saw it here on CSS-Tricks back in 2008. Demo The HTML The markup is relatively simple. <article class="glass down"><h1>Pelican</h1><p>additional content... The CSS We first size everything to the viewport.

Creating Decorated Ordered Lists With CSS 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. ol#clarke-laws { line-height: 1.6; list-style-type: none; counter-reset: section; margin-left: 3rem; Every new list item increments point by 1:

7 Things You Didn't Know You Could Do with CSS CSS and JavaScript, believe it or not, are starting to overlap as CSS adds more functionality.
