致力于使我的网站响应迅速。在达到一定宽度后，我希望我的一个 div 低于它之前的两个 div，并且 div 居中。问题是现在他们所做的只是在断点之后保持左对齐。在断点后如何让它们再次居中于页面？

有问题的 CSS 媒体查询:

@media only screen and (max-width: 1070px) {
.photo .design {
    text-align: center;
    margin: auto;   
}

.web {
    clear: left;
}

a.btn { clear: left;
}}

最佳答案

你很接近，只需更改 css 以针对 skills 元素，将 100% 的宽度添加到 skills 类，以及 text-align:center 像这样:

@media only screen and (max-width: 1070px) {
  .skills {
    width: 100%;
    text-align: center;
    margin: auto;
  }
  .web {
    clear: left;
  }
  a.btn {
    clear: left;
  }
}
