How to use style in html

The style attribute is used to apply styles directly to an element without the need for an external style sheet. It can specify the style of elements, such as color, font size, etc., but avoid overuse as it will affect performance and maintainability.

Usage of style attribute in HTML

What is the style attribute?

The style attribute is used to specify the style of an element. It applies style information directly to elements inline without using an external style sheet.

Usage

The value of the style attribute is a string containing a style declaration. Each style declaration consists of a property name and value, separated by a colon (:), and terminated by a semicolon (;).

For example:

<p style="color: red; font-size: 20px;">这段文字是红色的，字号为 20px。</p>

Advantages

• Convenient and fast, no need to write external style sheets.
• Suitable for elements that require dynamic or unique styling.

Limitations

• Style information is inlined in the HTML, which can lead to cluttered code.
• For large or complex styles, using an external style sheet is more appropriate.

Points to note

• The style attribute has a lower priority than styles declared in external style sheets.
• Try to avoid overuse of the style attribute as it affects performance and maintainability.
• You can use CSS abbreviations (such as background instead of background-color) to reduce the length of the style string.
