Analysis and solutions for reasons why CSS files externally referenced by HTML do not take effect

This article mainly introduces the analysis and solutions to the reasons why the HTML external reference css file does not take effect. This article is very detailed and has reference value. Friends who are interested can learn together. As a front-end novice, I have been tinkering with the front-end for a few days. . Today I suddenly discovered that something I believed in had a problem. . For example, I wrote a css style document under the css directory: style.css. At this time there is only one sentence in it:

body {    
background-color: #ddd;    
}

Then I introduce this external css into my html file:

<link rel="stylesheet" type="text/css" href="css/style.css">

Refresh the browser. . Wow, kao. It didn't respond, it didn't work. . I checked this path several times to make sure there was no problem, and opened chrome's F12 debugger. After making sure that the browser loaded the css file, I opened the file and saw:

I tried it later and used the sublime editor to modify the local css file encoding format to this utf-16LE:

Rewritten the css code. Save and run. . Sure enough, that's it. .
But my html is specified as utf-8, and the css is utf-16, which makes me very unhappy. . So I asked again for a solution. It can be solved, and it's simple. .
Change the css to utf-8 and edit the code inside. Just declare the encoding format when introducing this css in html:

That is, add an attribute to the link tag: charset="utf-8" Enough. . . It's really that simple. . .
