HTML5 Custom Data Attributes (data-*)

HTML5 Custom Data Attributes (data-*)
Have you ever found yourself using element class names or rel attributes to store arbitrary snippets of metadata for the sole purpose of making your JavaScript simpler? If you have, then I have some exciting news for you! If you haven't and you're thinking, Wow, that's a great idea! Thanks to HTML5, we now have the ability to embed custom data attributes on all HTML elements. Attribute Name The data attribute name must be at least one character long and must be prefixed with 'data-'. Attribute Value The attribute value can be any string. Using this syntax, we can add application data to our markup as shown below: <ul id="vegetable-seeds"> <li data-spacing="10cm" data-sowing-time="March to June">Carrots</li> <li data-spacing="30cm" data-sowing-time="February to March">Celery</li> <li data-spacing="3cm" data-sowing-time="March to September">Radishes</li></ul> We can now use this stored data in our site’s JavaScript to create a richer, more engaging user experience.

CSS Media Queries & Using Available Space We've covered using CSS media queries to assign different stylesheets depending on browser window size. In that example, we changed the layout of the entire page based on the space available. It isn't required that we make such drastic changes with this technique though, so in this tutorial we'll go over a design tweak with a smaller scope. We'll also cover the syntax for using media queries within a single stylesheet and more examples of that. The CSS media query syntax for calling an external stylesheet is like this: You may be familiar with the media attribute, normally being "screen" or "print" or even a comma separated list, like "screen, projection". Likewise, you can use more advanced CSS media queries like: You may use as many media queries as you would like in a CSS file. Example Let's say we have a fluid width design where the sidebar is 35% of the width of the page. In our example sidebar, we are going have a list of names of the Super Team which function as email links. Types

Media Queries Abstract HTML4 and CSS2 currently support media-dependent style sheets tailored for different media types. For example, a document may use sans-serif fonts when displayed on a screen and serif fonts when printed. ‘screen’ and ‘print’ are two media types that have been defined. A media query consists of a media type and zero or more expressions that check for the conditions of particular media features.
