需要准备的材料分别有：电脑、浏览器、html编辑器。
1、首先，打开html编辑器，新建html文件，例如：index.html，填充问题基础代码。
2、在index.html中的<span>标签中，输入样式代码：style="float: left;padding-top: 25px;"。
3、浏览器运行index.html页面，此时文字对准了图片的中间。

如果是普通模式，那就对图片、文字进行居中对齐和行高设置就可以了，代码如下：
<style>
.main{width:500px; height:350px; line-height:350px; margin:0 auto; background:url(img.gif) no-repeat;}
//设置宽度为500px,高度为350px,行高350px，相对于屏幕居中对齐，背景图片不重复
.txt{width:500px; height:350;line-height:350px; text-align:center;}
<div class='main'>
<div class='txt'>显示的文字内容</div>
</div>
如果想要特效显示，可以参考下面代码：
<style>
body {
text-align: center;
font-family: "Microsoft YaHei", "Microsoft Yahei", "微软雅黑", "", "Courier New", "Helvetica Neue", Courier, monospace;
background-color: #f1f1f1;
}
.pic-wrapper{
display: block;
position: relative;
margin: 15px auto;
width: auto;
height: auto;
background-size: contain;
transition: all ease .3s;
}
.pic-wrapper img{
display: block;
position: absolute;
z-index: 10;

}
.pic-wrapper .words-wrapper {

text-align: center;

}
.pic-wrapper .words-wrapper:hover {
background-color: rgba(0,0,0, .7);

.pic-wrapper .words-wrapper:hover .words {
