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.
Below, we will learn step by step how to clear the browser's default style.

CSS There is a technology called CSS Reset (CSS Reset). Its function is to completely clear the default style of page elements so that we can reset the style. . The advantage of this is that we can better control the style of page elements and reduce the interference of browser default styles.
The following is a relatively basic CSS Reset:
/* 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.
