Definition and Usage
The style property returns a CSSStyleDeclaration object, which represents an element's style attribute.
The style property is used to get or set a specific style of an element using different CSS properties.
Note: It is not possible to set styles by assigning a string to the style property, e.g. element.style = "color: red;". To set the style of an element, append a "CSS" property to style and specify a value, like this:
element.style.backgroundColor = "red"; // set the background color of an element to redTry it
As you can see, the JavaScript syntax for setting CSS properties is slightly different than CSS (backgroundColor instead of background-color).
For a list of all available properties, see our Style Object Reference.
Note: The style property only returns the CSS declarations set in the element's
inline style attribute, e.g.
<p style="color: red;">. It is not possible to use
this property to get information about style rules from the <head> section
in the document or
external style sheets.
However, you can access the <style> element from <head> by using document.getElementsByTagName():
var x = document.getElementsByTagName("STYLE")[0]; // get the first <style> element Try it
Note: It is recommended to use the style property instead of the element.setAttribute("style", "...") method, because the style property will not overwrite other CSS properties that may be specified in the style attribute.
