Clear css default style

In web development, we often use CSS (Cascading Style Sheets) to style web pages. However, we often encounter a problem when setting styles: the influence of browser default styles. When we do not set any styles, the browser will automatically set some default styles. These default styles may interfere with our page design, so we need to clear these default styles.

/* CSS Reset */
* {
   margin: 0;
   padding: 0;
   box-sizing: border-box;
}

This CSS Reset sets the margins, padding and box model of all elements to 0, and also adds the ## of the box model #box-sizing: border-box; property. The function of box-sizing is to allow us to more conveniently control the width and height of elements without having to consider the influence of borders and padding.

In web pages, link underlines are a very common element. However, in some cases, these underlines may interfere with the aesthetics of our web design. We can use the CSS text-decoration property to remove these underlines.

/* 清除有序列表默认样式 */
ol {
   list-style: none;
   padding: 0;
   margin: 0;
}
