The bootstrap framework has made some changes in this section, instead of pursuing zeroing, but rather focusing on resetting the styles that might create problems (such as Body,form's margin, etc.), preserving and adhering to some of the browser's basic styles, solving some of the potential problems, and improving the experience of some details, Specify the following:
- Remove a margin statement from body
- Set body's background color to white
- Basic font, font size, and line height are set for typesetting
- Sets the global link color, and the underline style is displayed when the link is in the suspended: hover state
Bootstrap's global style uses "normalize.css", but does not blindly use this reset style, but on this basis, some improvements have been made to make it more suitable for bootstrap design ideas.
