#What does the “C” in CSS stand for?

In CSS (Cascading Style Sheets), "C" stands for "Cascading".

The meaning of cascading

Cascading means that style rules from different sources can be applied to HTML elements in sequence. Cascading rules in CSS are based on the following principles:

• Specificity: More specific rules will override more general rules.
• Source: Rules in external style sheets have priority over inline styles.
• Order: Rules declared later will override rules declared first (unless they are more specific).

Example of cascading

The following example demonstrates how cascading works:

<code class="html"><p style="color: red">这是一个段落</p></code>

This HTML code sets the red text style for a paragraph .

<code class="css">p {
  color: blue;
}</code>

This CSS rule applies a blue text color to all paragraph elements.

Both style rules will be applied to paragraph elements when the page loads. According to the cascading rules, the CSS rules will override the inline styles, so the paragraph text will appear blue.

Importance

In CSS, cascading rules can be overridden by using the !important keyword. This will force the rule to be applied to the element regardless of the specificity or origin of other rules. However, it is important to use !important with caution as it may cause unexpected results.
