Question

我试图将图像水平居中于div，我不明白为什么它不起作用......我已经多次居中图像了，这个时间我只是不明白...... 这是我尝试过的......

CSS

#cabeca{
position: relative;
float: left;
width: 100%;
height: auto;
min-height: 290px;
margin: auto;
}

.cabecasize {
width:100%;
min-width: 968px;
height:auto;
min-height: 290px;
overflow:hidden;
left:0;
right: 0;
margin: auto;
}

.cabecafundo{
position: absolute;
width: 100vw;
left: calc(-50vw + 50%);
background-color: black;
height: 100%;
top:0;
z-index: -1;
}

.overcabeca{
overflow: hidden;
display: block;
margin: auto;
text-align: center;
}

HTML

<div id="cabeca">
    <div class="overcabeca">
        <img src="images/av61.png" alt="av61" class="cabecasize" />
    </div>
    <div class="cabecafundo">
    </div>
</div>

任何想法??

.image {
  text-align: center;
  background: #c0c0c0;
  border: #a0a0a0 solid 1px;

/*   content: '';
  margin-left: -0.25em; */
