HomeWeb Front-endFront-end Q&AWhat to do if css style doesn't work

CSS (Cascading Style Sheets) is a language that defines the appearance of web pages. It can provide styling and layout for HTML (Hypertext Markup Language) text.

  1. Incorrect CSS file path

Incorrect CSS file path will cause the style sheet to fail to load. Make sure the CSS file path is correct, an easy way is to use relative paths. A relative path starts from the location of the current page, which should point to the correct location of the CSS file.

  1. Errors in the CSS code in the HTML document

There may also be errors in the CSS code used to set styles in the HTML document. This may be because the CSS code contains duplicate rules, incorrect attributes, or misspelled selector names.

  1. Inherited styles have higher priority

When CSS styles are applied to page elements, they are applied one by one in order of priority. However, if styles with inherited properties are called, these styles will be applied to the element before other styles. If the priority of these inherited properties is too high, it may prevent other styles from being applied.

  1. Make sure the CSS file path is correct

If the priority of a style that inherits a property is too high, another style must be introduced to override its priority. In this case, you can add ! important to increase the priority.

  1. Make more flexible rules

Using ID selectors is not inherently bad in CSS, but should be used with caution. 1) ID selector is suitable for unique elements or JavaScript hooks. 2) For general styles, class selectors should be used as they are more flexible and maintainable.
