求助，我的banner不是100%宽，我想让它居中，请教怎么改？
html是这些____________________________________
<div class="aad clearfix wow slideInDown">
<div id="owl-demo" class="owl-carousel">
{m:banner field="image" limit="5"}
{loop $data $v}
<div class="item">
<img src="{$v[image]}" />
</div>
{/loop}
</div>
</div>
CSS是这些____________________________________
/* display none until init */
.owl-carousel{
display: none;
position: relative;
width: 100%;
-ms-touch-action: pan-y;
max-width: 1280px;
}
.owl-carousel .owl-wrapper{
display: none;
position: relative;
-webkit-transform: translate3d(0px, 0px, 0px);
}
.owl-carousel .owl-wrapper-outer{
overflow: hidden;
position: relative;
width: 100%;
}
.owl-carousel .owl-wrapper-outer.autoHeight{
-webkit-transition: height 500ms ease-in-out;
-moz-transition: height 500ms ease-in-out;
-ms-transition: height 500ms ease-in-out;
-o-transition: height 500ms ease-in-out;
transition: height 500ms ease-in-out;
}
.owl-carousel .owl-item{
float: left;
}
.owl-controls .owl-page,
.owl-controls .owl-buttons div{
cursor: pointer;
}
.owl-controls {
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}
自己回答了 margin：0 auto；就好了，不过是在更上层的DIV里加的 .aad{ text-align: center; margin：0 auto position: relative; z-index: 20; max-width: 1280px; }
