ID selectors Redirect 1


In an HTML document, CSS ID selectors match an element based on the contents of that element's ID attribute, which must match exactly the value given in the selector.


#id_value { style properties }

Note this is equivalent to the following attribute selector:

[id=id_value] { style properties }


span#identified {
  background-color: DodgerBlue;
<span id="identified">Here's a span with some text.</span>
<span>Here's another.</span>
