Through summaries of key concepts and CSS examples, this article aims to describe how you can override FSS styles and classes with your own CSS styles.

More technical details and background information regarding the CSS concepts  are provided at the W3C.

Key Concepts

The following are HTML and CSS concepts that you may find helpful to have knowledge of before proceeding to learn how to override FSS styles.


The structure of HTML is hierarchical and can be compared to a tree structure, where one element, or HTML tag (eg. <body>, <p>) has the following characteristics:

  1. It can contain several "child" elements
  2. It belongs to only one "parent" element
  3. It can have several "ancestor" elements (parents of its parent element)
  4. It can have several "descendent" elements (children of its child elements)

CSS can support such a structure by allowing child elements to inherit certain properties of their parents when specified.


CSS Style Sheet

p { font-family: inherit; }

div { font-family: "Arial"; }

<p>This is another paragraph inside the body tag.</p>

<div>This is another section inside the body tag, but it is separate from the paragraphs.</div>
