HTML and CSS Reference
In-Depth Information
removed the
<body>
tag and all of its content, you'd still see two hash
symbols on the page: one in the
<html>
element, and one in the
<body>
tag, which the browser automatically constructs.
Characteristics Of Inserted Content
As mentioned, the content that is inserted is not visible in the page's source.
It's visible only in the CSS.
Also, the inserted element is by default an inline element (or, in HTML5
terms, in the category of text-level semantics). So, to give the inserted
element a height, padding, margins and so forth, you'll usually have to
define it explicitly as a block-level element.
This leads well into a brief description of how to style pseudo-elements.
