CSS code: a[href] {background-color:yellow}
HTML code: <a href="www.siteforinfotech.com" target=_blank>Infotech Site</a>

Using Multiple Attribute Selectors
You can select HTML elements by combining more than one attribute selectors or combining with basic selectors as given below. p.post[title] {background-color:red;}
It would select any <p> tag with the class “post” and with title attribute set.
#sidelinks a[href="http//"] {font-weight:bold;}
It would select any <a> tags which are descendents of some element with an id value of “sidelinks” that have href values that start with “http://” and make them bold.
You can also use multiple attribute characteristics at once as the following.
p[title="Test"] [lang|="en"] {border: 2px solid blue;}
It would select a <p> tag with title “Test” and a lang value in the English family and sets blue border having 2px solid.
