How to remove css style

In web design, CSS style is an important means to optimize the front-end page, which can make the website look more beautiful and comfortable. But sometimes, we may need to remove certain styles, whether to resolve style conflicts or simply to better debug and test the code. This article will introduce various methods to remove CSS styles, as well as the advantages, disadvantages and applicable scenarios of these methods.

Delete the style sheet directly

The most direct way is to delete the style sheet directly. The advantage of this method is that it is simple and direct without any side effects. Simply comment out the link to the stylesheet in the HTML file to complete the removal. For example:

<!-- <link rel="stylesheet" href="style.css"> -->

However, the shortcomings of this method are also very obvious. If the style needs to be re-enabled, the code needs to be modified manually, which is very troublesome. And if you delete the style sheet, all styles will be invalidated instead of just modifying certain parts.

Override styles

If you just want to override certain styles, you can write the corresponding styles in your own CSS file and overwrite the original styles. For example, the original style is as follows:

p {
  font-size: 16px;
  color: #333;
}

If you want to override these styles, just write in your own style file:

p {
  font-size: 14px;
  color: #000;
}

In this way, all p tags will use the new style. But this method also has flaws. When overriding the style, you need to pay attention to the weight issue. If the original style uses !important, then this method is not feasible. In addition, if you want to cover multiple styles, it is very troublesome to write the styles manually.

Reset style

The disadvantage of overwriting styles is that you need to write the styles manually, while resetting styles resets all styles to the browser default style. The advantage of resetting the style is that you don't need to write the style manually and it can ensure the consistency of the style.

For example, the original style is as follows:

p {
  font-size: 16px;
  color: #333;
  margin-bottom: 20px;
}

The method to use the reset style is as follows:

p {
  margin: 0;
  padding: 0;
  font-size: 100%;
  font-weight: normal;
}

In this way, all p tags will be reset to browse The default style of the browser without the need to manually override the style. However, this method also has flaws. Since the default styles of different browsers are different, the effects on different browsers may be different. Moreover, resetting styles is too comprehensive, which may cause some styles to be reset and require targeted modifications.

Use Reset.css

Reset.css is a relatively mature solution for resetting styles. It does not delete styles or manually overwrite styles, but resets all styles to Browser default style. The benefit of Reset.css is that it has been tested and practiced many times to ensure compatibility and consistency. At the same time, Reset.css also provides many targeted styles to avoid style problems caused by using reset styles.

Various versions and sources of Reset.css can be found online, the more famous ones include Normalize.css, Eric Meyer's Reset CSS, etc. Take Normalize.css as an example. Its use is very simple. You only need to add a link to the head of the HTML file:

<link rel="stylesheet" href="normalize.css">

Normalize.css will make subtle adjustments based on the browser's default style. , ensuring consistent results throughout.

Use Tools

In addition to manually resetting styles, you can also use some CSS tools to speed up the process of removing styles and improve efficiency. The more popular tools include:

• CSS Reset tool: can generate targeted reset styles.
• CSS Preprocessor: Quickly write, reuse and combine CSS styles.

Use these tools to quickly remove some unwanted styles, such as removing text selection styles, removing form default styles, etc. However, it should be noted that when using tools, you must also weigh the impact they bring. Sometimes using tools is not the best choice, and may cause the code to be too bloated, affecting code quality and maintainability.

Summary

When dealing with CSS styles, there are many ways to remove certain styles, and each method has its applicable scenarios, advantages and disadvantages. Deleting the style sheet is the simplest and most straightforward method, but it requires manual code modification. Overriding the style can modify the style in a targeted manner, but you need to pay attention to the weight issue.
