正在努力使我的网站具有响应能力。经过一定的宽度后,我希望我的一个div降到之前的两个以下,并且div居中。现在的问题是,他们所做的只是在断点之后保持对齐。我如何使它们在断点之后再次居中于页面上?

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

亲密无间,只需更改css以定位skills元素,为skills类添加宽度100%,然后将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;
  }
}
