// Clearfix // // For modern browsers // 1. The space content is one way to avoid an Opera bug when the // contenteditable attribute is included anywhere else in the document. // Otherwise it causes space to appear at the top and bottom of elements // that are clearfixed. // 2. The use of `table` rather than `block` is only necessary if using // `:before` to contain the top-margins of child elements. // // Source: http://nicolasgallagher.com/micro-clearfix-hack/ .clearfix() { &:before, &:after { content: " "; // 1 display: table; // 2 } &:after { clear: both; } } 国产呦萝小初合集,久久香蕉国产线看观看乱码,俄罗斯破女处视频免费观看
