What to put in CSS?

CSS is the abbreviation of Cascading Style Sheets. The Chinese translation is Cascading Style Sheets. It is a language used to describe document styles such as HTML (Hypertext Markup Language) or XML (Extensible Markup Language). It can Help users create a variety of different visual effects and make the website more beautiful and easy to read. However, in actual use, many developers will encounter a problem - where should CSS be placed?

There are three placement locations for CSS:

1. Inline style: Write the CSS code directly into the style attribute of the HTML tag. For example, to set the h1 tag color to red, you can write:

1a55d6c3c5eb7232c4b01f8683b7c348This is a first-level title473f0a7621bec819994bb5020d29372a

The advantage of using inline styles is that they take effect directly and are simple and easy to use, but they will increase a lot of HTML code and are difficult to maintain and modify.

2. Internal style sheet: Use the c9ccee2e6ea535a969eb3f532ad9fe89 tag in the head tag of the HTML document to define CSS. For example:

 <title>网站标题</title>
 <style>
      h1 {
           color: red;
           font-size: 24px;
      }
 </style>

The advantage of using internal style sheets is that it can make the code clearer and easier to maintain and modify. , but for some pages, a large amount of CSS code may be required, which will cause the HTML file to become very bloated.

3. External style sheet: Store the CSS code separately in an external file, and then introduce it in the HTML document through the 2cdf5bf648cf2f33323966d7f58a7f3f tag. For example:

93f0f5c25f18dab9d176bd4f6de5d30e

 <title>网站标题</title>
 <link rel="stylesheet" href="style.css">

The advantage of using an external style sheet is that it can share styles so that multiple pages can Being able to reference the same CSS file avoids the problem of duplication of code, making the code easier to maintain and modify. The disadvantage is that one more HTTP request needs to be initiated, which may reduce the page loading speed.

In actual use, we should choose different placement locations based on project needs and actual conditions. Generally speaking, for some small personal websites or relatively simple pages, we can use inline styles or internal style sheets to make the code more intuitive and easy to modify. For some large corporate websites or pages with complex animation effects, we can use external style sheets to reduce redundant code and improve performance and ease of maintenance.

To sum up, there are no certain regulations on where to place CSS, and you need to make a choice based on the specific situation. We can determine where it should be placed based on project needs and market conditions to achieve good development results and user experience.
