Type selectors
The CSS type selector matches elements by node name. In other words, it selects all elements of the given type within a document.
/* All <a> elements. */ a { color: red; }
Type selectors can be namespaced when using @namespace. This is useful when dealing with documents containing multiple namespaces such as HTML5 with inline SVG or MathML, or XML that mixes multiple vocabularies.
- 
ns|h1- matches<h1>elements in namespace ns - 
*|h1- matches all<h1>elements - 
|h1- matches all<h1>elements without any declared namespace 
Syntax
element { style properties }
Examples
CSS
span { background-color: skyblue; }
HTML
<span>Here's a span with some text.</span> <p>Here's a p with some text.</p> <span>Here's a span with more text.</span>
Result
Namespaces
In this example the selector will only match <h1> elements in the example namespace.
@namespace example url(http://www.example.com); example|h1 { color: blue }
