Ich habe Pseudoelemente:after在左侧对齐块列表的最后一行。我使用space-evenly来证明这些块的合理性。我的问题是最后一行的块与用户不对齐，因为:afterverwendet, um Platz einzunehmen. Wie kann ich dieses Problem lösen?
.exposegrid { width: 500px; display: flex; flex-flow: row wrap; justify-content: space-evenly; &:after { content: ""; flex: auto; } } .exposetab { width: 100px; height: 66px; background-color: rgba(255, 255, 255, 0.2); border: 1px solid rgba(0, 0, 0, 0.4); border-radius: 5px; box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2); margin-bottom: 10px; }
:after 伪元素占用了 Flex 容器中的空间并干扰了最后一行中项目的对齐，这是您遇到问题的根本原因。在:after 伪元素上使用边距作为 flex auto 的替代方案是解决此问题的一种方法。这是最新版本的 CSS：
.exposegrid { width: 500px; display: flex; flex-flow: line wrapping; justify-content: spatially even; &:after { content: ""; flex: none; /* disable flex grow/shrink */ width: calc((100% - (100px * 4)) / 4); /* calculate border width */ } } .exposetab { width: 100px; height: 66px; background-color: rgba(255, 255, 255, 0.2); border: 1px solid rgba(0, 0, 0, 0.4); border-radius: 5px; box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2); margin-bottom: 10px; } /* Add margin to last item in each line */ .exposegrid > *:nth-child(4n+4) { right margin: 0; }.exposegrid { width: 500px; display: grid; grid-template-columns: repeat(auto-fill, 100px); /* this will create cells that will fill the space , if there is space of five, then each row will have five*/ gap: 10px /*instedt of margin, use gap to space cells*/ } .exposetab { width: 100px; height: 66px; background-color: rgba(255, 255, 255, 0.2); border: 1px solid rgba(0, 0, 0, 0.4); border-radius: 5px; box-shadow: 1px 1px 2px rgba(0, 0, 0, 0.2); }
