CSS Super Tips (2)

css| tips Five. Default value

Usually the default value for the padding is transparent, which is the default value for 0,background-color. However, the default values for different browsers may be different. If you are afraid of conflict, you can define the margin and padding values for all elements at the beginning of the stylesheet as 0, like this:

* {
margin:0;
padding:0;
}

Six. You do not need to repeat the definition of inheritable values

In CSS, child elements automatically inherit the attribute values of the parent element, such as color, font, and so on, that are already defined in the parent element and can be directly inherited in child elements, without having to repeat the definition. Note, however, that the browser may overwrite your definition with some default values.

Seven. Recent priority principles

If there are multiple definitions of the same element, the closest (least level) definition is the highest priority, such as a piece of code
