Summarize some methods of linking CSS files

Apr 13, 2023 am 10:27 AM

CSS (Cascading Style Sheets) is a very important part when creating web pages. CSS can define and control the appearance and layout of all text and elements on the page. However, for beginners, how to link CSS correctly can be a difficult problem. In this article, we’ll cover some ways to link CSS files to help you master the process more easily.

Internal Style Sheet Linking

First, you can use an internal style sheet to link your CSS files. This can be done by using the <style> tag within the <head> tag in the HTML document. In the <style> tag you can enter CSS code. Here's an example:

&lt;!DOCTYPE html&gt;
&lt;html&gt;
  &lt;head&gt;
    &lt;style&gt;
      h1 {
        color: red;
      }
      p {
        font-size: 16px;
      }
    &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;h1&gt;This is a heading&lt;/h1&gt;
    &lt;p&gt;This is a paragraph.&lt;/p&gt;
  &lt;/body&gt;
&lt;/html&gt;

Copy after login

The HTML document here stores all CSS code in <style> tags. This method is suitable for making simple changes and modifications to CSS styles, but if you wish to change the style, you will need to change the HTML file.

External style sheet link

The second method is to use an external style sheet to link the CSS file. This can be achieved in an HTML document using the <link> tag. <link>The tag needs to point to the path to your CSS file to let the browser know where to find it. Here is an example of linking to an external style sheet:

&lt;!DOCTYPE html&gt;
&lt;html&gt;
  &lt;head&gt;
    &lt;link rel=&quot;stylesheet&quot; type=&quot;text/css&quot; href=&quot;style.css&quot;&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;h1&gt;This is a heading&lt;/h1&gt;
    &lt;p&gt;This is a paragraph.&lt;/p&gt;
  &lt;/body&gt;
&lt;/html&gt;

Copy after login

Here, the <link> tag points to a file named "style.css". The file name and path can be changed according to your needs. The CSS file should be on the same server as the HTML file.

Inline Style Sheet Linking

The third method is to use an inline style sheet to link CSS into the HTML document. This can be done by entering CSS code in the style attribute inside the HTML element. Here is an example:

&lt;!DOCTYPE html&gt;
&lt;html&gt;
  &lt;head&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;h1 style=&quot;color:red;&quot;&gt;This is a heading&lt;/h1&gt;
    &lt;p style=&quot;font-size:16px;&quot;&gt;This is a paragraph.&lt;/p&gt;
  &lt;/body&gt;
&lt;/html&gt;

Copy after login

Here, the style attribute is used to embed CSS code. While this approach may be more convenient, it is difficult to maintain and change, and may lead to code duplication.

Summary

When connecting CSS files, the best way is to use an external style sheet. This approach is easier to maintain and makes your code more readable and scalable. For smaller projects, consider using internal style sheets. In all cases, you can use inline style sheets to quickly change your code, but you should be aware that they can lead to code duplication and difficult maintenance problems.
