These generally affect older browsers. The load Method Until fairly recently, the load method was required in order to tell the browser about a change in the media source and to get it to update appropriately. So for older browsers, such as Firefox 3. Autoplay and Volume iOS and Blackberry devices ignore the autoplay attribute and media element volume changes, whereas Android supports autoplay but not volume changes.

The quotes are not required here, but err on the safe side and include them. When writing multiple values in a class attribute, separate them with two spaces, thus: Read more in Grouping related classes in your markup.
As with our rulesets, it is possible to use meaningful whitespace in your HTML. You can denote thematic breaks in content with five 5 empty lines, for example: Remembering your own classes, rules, objects, and helpers is manageable to an extent, but anyone inheriting CSS barely stands a chance.
CSS needs more comments. As a result of CSS not telling its own story very well, it is a language that really does benefit from being heavily commented. That is to say, there is no need to tell someone that color: High-level For large comments that document entire sections or components, we use a DocBlock-esque multi-line comment which adheres to our 80 column width.
Object—Extension Pointers When working across multiple partials, or in an OOCSS manner, you will often find that rulesets that can work in conjunction with each other are not always in the same file or location. For example, you may have a generic button object—which provides purely structural styles—which is to be extended in a component-level partial which will add cosmetics.
We document this relationship across files with simple object—extension pointers. In the object file: Low-level Oftentimes we want to comment on specific declarations i.
To do this we use a kind of reverse footnote. Here is a more complex comment detailing the larger site headers mentioned above: This percentage gives us a When the viewport is at px wide, our Preprocessor Comments With most—if not all—preprocessors, we have the option to write comments that will not get compiled out into our resulting CSS file.
As a rule, use these comments to document code that would not get written out to that CSS file either. If you are documenting code which will get compiled, use comments that will compile also. For example, this is correct: Default icon size is 16px.
Squash down the retina sprite to display at the correct size. This means that we have only the correct and relevant information available to us when debugging our compiled stylesheets. Removing Comments It should go without saying that no comments should make their way into production environments—all CSS should be minified, resulting in loss of comments, before being deployed.
Naming Conventions Naming conventions in CSS are hugely useful in making your code more strict, more transparent, and more informative. A good naming convention will tell you and your team what type of thing a class does; where a class can be used; what else a class might be related to.
The naming convention I follow is very simple: Hyphen Delimited All strings in classes are delimited with a hyphen -like so: Whilst BEM is a complete methodology, here we are only concerned with its naming convention. Further, the naming convention here only is BEM-like; the principles are exactly the same, but the actual syntax differs slightly.
And of course you need to verify. This is a follow up to my article Native Audio in the Browser, which covers the basics of HTML5 yunusemremert.com may well be worth reading if you want to get a feel for the element and associated API..
Now, two and a half years later, it’s time to see how things are progressing. At Lucid Software, we strive to build desktop quality software that runs in the browser. Until recently, however, we had settled for using our own internal clipboard implementation rather than the system clipboard — limiting copying and pasting with external applications to just plain text.
