How to clear css style

Clearing CSS styles means clearing all existing styles on the page and returning the elements to their initial state. During development, sometimes we need to clear the default style of an element or remove the previous style to achieve the effect we want. Here are a few ways to clear CSS styles.

1. Use Universal Selector

Universal Selector (wildcard selector) can match any element on the page. We can use this to set the styles of all elements to default values, thereby clearing all styles. The code is as follows:

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
  font-size: 16px; /* 可根据需要自行修改 */
  font-family: sans-serif; /* 可根据需要自行修改 */
  /* 其他默认样式 */
}

This example sets the margins and padding of all elements to 0, changes the box model to border-box, the font size to 16px, and the font to sans-serif and other common default values. By clearing styles in this way, we can return elements to their original state.

2. Using normalize.css

normalize.css is an open source CSS file that can repair and improve the browser's style without destroying the default style. surface. Use normalize.css to give your web pages a consistent look and behavior across multiple browsers.

Using normalize.css in your project is very simple. First, you need to download the normalize.css file from the official website. Then, put it into the project and include it in the HTML.

In this way, after using normalize.css, the elements on the page will behave consistently across browsers without the need to readjust the style sheet.

3. Use reset.css

reset.css is similar to normalize.css, and is used to reset the browser's default style. reset.css will set the styles of all elements to zero and then redefine the styles. The method of using reset.css is also very simple. You only need to download it and introduce it into the project.

It should be noted that although reset.css and normalize.css can both clear all styles, they do so in different ways. normalize.css works to enhance and repair the browser's default style, while reset.css completely resets the browser's default style. According to actual needs, just choose a cleaning method that suits you.

Summary

There are many ways to clear CSS styles. During the design and development process, we need to choose a cleaning method that suits us based on actual needs. Whether using wildcard selectors, normalize.css, or reset.css, you can restore page elements to their initial state. Clearing CSS styles can not only improve development efficiency, but also make the page more standardized and easier to maintain.
