Question

我是CSS和网站开发的新手，并且经常使用格式。我使用了预先构建的主题，并对其进行了自定义以满足其客户的需求，并且无法更改悬停在图像上的文本的位置。

我添加了一半的html代码。有人可以帮我吗

我试图在css中使用float：center，align-text：center但没有任何作用

.home-category .block-center .inner-top a{
    float:center;/* changed left*/
    left:9px;
  }
.home-category .block-center .inner-top a.frist{
    margin-right:28px;
}
.home-category .block-center .inner-bottom{
    margin-top: 14px;
    float:center;/* changed left*/
}
.home-category .block-right .inner-bottom{
    margin-top: 14px;
}
.home-category .info{
    position:absolute;
    top:50%;
    left:50%; /*removed */
    margin-top:-13px;
}
.home-category .info a{
    color:#fff;
    font-size:0;
    float:center;
    text-transform:uppercase;
    position:relative;
    font-weight:bold;
    transition: all 0.3s;
    -webkit-transition: all 0.3s;
    -moz-transition: all 0.3s;
    -o-transition: all 0.3s;
    white-space:nowrap;
}
.home-category .info a:before{
    float:center;
    content: "";
    height: 0px;
    opacity: 0;
    position: absolute;
    left:50%;
    top: 50%;
    transition: all 0.2s ease-out 0s;
    -webkit-transition: all 0.2s ease-out 0s;
    -moz-transition: all 0.2s ease-out 0s;
    -o-transition: all 0.2s ease-out 0s;
    visibility: hidden;
    width: 0px;
}
/*hover block left*/
.home-category .block-left:hover .info a{

    font-size:128.57%;
    transition: all 0.3s;
    -webkit-transition: all 0.3s;
    -moz-transition: all 0.3s;
    -o-transition: all 0.3s;
    margin-left:-25px;
    margin-top:-13px; 
}
.home-category .block-left:hover .image:before{
    transform: scale(1);
    visibility:visible;
    transition: all 0.3s ease-in-out 0s;
    -webkit-transition: all 0.3s ease-out 0s;
    -moz-transition: all 0.3s ease-out 0s;
    -o-transition: all 0.3s ease-out 0s;
    opacity:1;
}
.home-category .info a:hover{
    color:#25bce9
}
.home-category .block-left:hover .info a:before{
    transition: all 0.2s ease-out 0s;
    -webkit-transition: all 0.2s ease-out 0s;
    -moz-transition: all 0.2s ease-out 0s;
    -o-transition: all 0.2s ease-out 0s;
    height:150px;
    width:150px;
    visibility:visible;
    opacity:1;
    margin-top:-75px;
    margin-left:-75px;
}

Answer 1

我发现需要对您在此处发布的css文件进行一些调整，请尝试以下更改

.home-category .info{
    position:absolute;
    top:50%;
    width:100%;
    left:0;       
  }



.home-category .info a{
    color:#fff;
    text-align:center
    text-transform:uppercase;  
    font-weight:bold;
    transition: all 0.3s;
    -webkit-transition: all 0.3s;
    -moz-transition: all 0.3s;
    -o-transition: all 0.3s;
    white-space:nowrap;
}

Answer 2

您可以这样：

.image {
  display: inline-block;
  position: relative;
  padding: 5px;
  line-height: 0;
}

.image span {
  position: absolute;
  left: 0;
  top: 50%;
  width: 100%;
  text-align: center;
  display: none;
  font-size: 20px;
}

.image:hover span {
  display: inline-block;
}

<div class="container">
<div class="image"><img src="https://via.placeholder.com/250x150" /> <span>Some text</span></div>
<div class="image"><img src="https://via.placeholder.com/125x150" /> <span>Some text</span></div>
<div class="image"><img src="https://via.placeholder.com/175x150" /> <span>Some text</span></div>
<div class="image"><img src="https://via.placeholder.com/400x150" /> <span>Some text</span></div>
<div class="image"><img src="https://via.placeholder.com/175x150" /> <span>Some text</span></div>
</div>

首先，您需要设置line-height: 0以防止垂直间隙。

使用position: absolute并将top: 50%设置为垂直居中。

接下来，使用width: 100%和text-align: center进行水平居中。

Answer 3

您可以使用display: flex;将div从顶部和左侧居中。在CSS下方使用：

.home-category .info{
    position:absolute;
    top:0%;
    left:0%; 
    margin-top:0;
    width: 100%;
    height: 100%;
    display: flex;
    align-items: center;
    justify-content: center;
}
