Universal Selectors in CSS

A selector is an HTML tag at which a style will be applied. This could be any tag like <h1> or <table> etc.

With the type selector, set for HTML tags like h1, h2, h3, p, etc:

h2 {
   color: #FFFF00;
}

Rather than selecting elements of a specific type, the universal selector simply matches the name of any element type:

* {
   color: #FFFF00;
}
