Definition and usage of cssborder-left-width

1. In css, the border-left-width attribute is used to set the width of the left border of the element. Similar attributes are: the border-top-width attribute, the border-bottom-width attribute, and the border-right-width attribute, which are used the same as the border-left-width attribute.

2. Set the border style (border-style or border-left-style) before setting the border-left-width property to have an effect, otherwise the border style is none and the border width will be reset to 0. It can be understood that there must be a border before there is a border width.

3. The border-left-width attribute value is not allowed to be a negative length value.
