The css file in the web page has no effect after being introduced ? How to solve the

tracking problem:

1. Open the web debugging tool and see if there are any errors.

A common error is that the imported file is at the target address. This file does not exist, causing the css to not take effect.

For example, the console of the Chrome browser will usually tell you what errors have occurred:

The errors that will generally be told are: File Does not exist, javascript error, etc.,

##2. Pay attention to whether the rel="stylesheet" of the link tag is wrong. If it is wrong, the general css will not take effect. The corresponding effect of css cannot be seen on the page:

<link rel="stylesheet" href="bootstrap/css/bootstrap.css" type="text/css" charset="utf-8"/>
