The CSS border properties allow you to specify the style and color of an element's border. In HTML we use tables to create borders around a text, but with the CSS border properties we can create borders with nice effects, and it can be applied to any element.
CSS边框属性可以让你指定元素边框的样式和颜色。HTML中我们可以用表格来建立文字的边框，但使用CSS边框属性能让我们建立更好看的效果而且它可以支持任何元素。
