Do you know what CSS reset is? In general, it is also written as reset CSS, that is, resetting the style of the browser. In various browsers, some default values are used for CSS selectors. For example, if H1 is not set, a certain size is displayed. However, not all browsers use the same value. Therefore, with CSS reset, the webpage style is consistent in different browsers.
You are using CSS. Have you used CSS reset? Of course, you may have used it, but you do not know that it is in use. For example, you may have used:
* {Padding: 0; margin: 0; Border: 0 ;}
This is also a CSS reset method that sets the padding, margin, and border values of all selectors to 0. This is a powerful method and the simplest and safest method. However, it is also the most resource-consuming method. For small websites, using this will not cause a great waste of resources, but if it is a website with a very large architecture like Yahoo, you just need to selectively reset CSS, to reduce resource waste. Below is Yahoo's CSS resettingCodeIs also the most popular CSS reset method. The Yui method is as follows:
Body, Div, DL, DT, DD, UL, ol, Li, H1, H2, H3, H4, H5, H6, pre,
Form, fieldset, input, textarea, P, BLOCKQUOTE, Th, TD {
Padding: 0;
Margin: 0;
}
Table {
Border-collapse: collapse;
Border-Spacing: 0;
}
Fieldset, IMG {
Border: 0;
}
Address, caption, cite, code, dfn, em, strong, Th, VAR {
Font-weight: normal;
Font-style: normal;
}
OL, UL {
List-style: none;
}
Caption, Th {
Text-align: left;
}
H1, H2, H3, H4, H5, H6 {
Font-weight: normal;
Font-size: 100%;
}
Q: before, Q: After {
Content :";
}
Abbr, acronym {border: 0;
}
OK. I believe you have understood the purpose of CSS resetting. Maybe you can write your own CSS resetting System Based on your preferences, after all, the requirements and habits of everyone are different. You can refer to the following:

As you can see, these are similar, and the methods vary depending on different requirements. I prefer Yahoo CSS reset and use Yahoo code. Do you have your own CSS Reset System? Maybe you can share it!
