Where should the css style be written?

The best choice for placement of CSS styles is: external style sheets (.css files) because it provides reusability, caching, and maintenance ease. Inline style sheets ( tags) if external style sheets cannot be used. Inline styles (style attribute) are used only as a last resort to style specific elements.

Placement of CSS Styles

CSS (Cascading Style Sheets) is used to describe the visual presentation of a web page, such as Fonts, colors and layout. It can be written in different locations, each with its own advantages and disadvantages.

1. External style sheet: .css file

Advantages:

Styles can be reused, applicable on multiple pages. Can be cached to speed up page loading. Easy to maintain because styles are concentrated in one file. Disadvantages:

Added additional HTTP requests. 2. Embedded style sheet: tag

##Advantages:

Styles only apply to the current page. No additional HTTP requests required. Disadvantages:

Not suitable for repeated use. Increased the size of HTML files. It is more difficult to maintain. 3. Inline style: style attribute

Advantages:

Styles only apply to specific elements. No additional code or files required. Disadvantages:

Very unsuitable for reuse. Making HTML code difficult to read and maintain. May affect page loading speed. Best Practices

For most situations, using an external style sheet is recommended.

It provides style reusability, caching and maintenance convenience. Use inline or inline styles only when external style sheets cannot be used.
