Issue #22  (style object, Git/Github, RWD, CSS)


(Skip to the tools section below)

Many of you are probably familiar with the style object that is accessible via JavaScript to give you CSS information for a given element. Unfortunately, the style object will only give you access to CSS that is applied via the style attribute on the HTML element, so it is of limited use.

Nonetheless, you may find it handy to know that the style object has some lesser-known properties and methods. Firstly, when using the style object, you can access inline styles individually by simply camel-casing them:
 
// get bg color defined via inline styles
var bgc = element.style.backgroundColor;

Remember, this technique will not glean any information from styles that cascade from a style tag or from a linked stylesheet; it will only get styles that are defined inline on the style attribute in the HTML. But in addition to the individual properties, you can also use a few other features.

You can get the full list of applied inline styles using the cssText property:
 
var inlineStyles = element.style.cssText;

Which will spit out a string like "background-color: blue; float:left;" (or whatever is defined via inline styles).

Using length, you can get the number of different long-hand properties defined on a single element:
 
var inlineStyles = element.style.length;

Note that although you might only have 3 inline styles defined, this might return a larger number than 3, because, as mentioned, it returns the number of longhand styles. So if the only style present was "border: solid 1px #ccc" then instead of returning "1", the length would (oddly) return "17". This includes all the border-related properties that make up border shorthand, along with all the border-image related properties (which can be reset using border but not defined directly).

You can also get the "priority" of an inline declaration:
 
var getPriority = element.style.getPropertyPriority('width');

So in this case, if the width property was defined inline using the !important keyword, this would return a value of "important". Otherwise it will return nothing.

Of course, since we do well to avoid inline styles as much as possible, these features might have limited use. But if you have a case where user-generated content is adding inline styles, or if you're using/writing an animation library that adds styles inline, these might come in handy.

You can see these in action in this JS Bin demo. And here's some further reading:
