拨开荷叶行,寻梦已然成。仙女莲花里,翩翩白鹭情。

使用 z-index 时调整影像大小的问题

uj5u.com热心网友回复:

嘿伙计,我真的不知道这是否是正确的做法,但它似乎作业得很好。我所做的是将宽度更改为最大宽度,使其从 60% 变为 18%。它看起来不错,就像上课一样。然后,当您将其切换到平板计算机或移动设备时,我让@media 功能将其改回 60%,这样它就不会一直缩小并且看起来很奇怪。idk,如果我解释正确但这里是代码:

    .title-image {
      max-width: 18%;
      transform: rotate(25deg);
      position: absolute;
      right: 22%;
      }

      @media (max-width: 991px) {
       .title-image {
       position: static;
       transform: rotate(0deg);
       max-width: 60%;
        }
         }
    

我和你一样是一个完整的初学者,但我希望这对你有所帮助。

uj5u.com热心网友回复:

你只需要设定position你的第一部分来实作这一点,如果你设定title'sposition: relative;z-index: -1;,你就不需要在你的.title-image班级上设定位置。请参阅下面的片段(整页)以供参考。
