我有以下JSFiddle:http://jsfiddle.net/eotamvwy/
HTML:
<div class="infobox-container">
<div class="triangle-l"></div>
<div class="triangle-r"></div>
<div class="infobox">
<h3><span>This is the Header</span></h3>
<p>This is the content of the infobox.<p/>
</div>
</div>
如何修改CSS以使其响应?
我有一个具有以下风格的div:
width: 98%
padding: 0 1% 0 1%
我想在里面插入infobox-container
并将其拉伸100%并根据上面的div调整大小。
答案 0 :(得分:2)
使用百分比单位表示响应度,对于不需要额外元素的三角形,您可以在:after
上使用:before
和.infobox h3
:伪元素。

我认为您可以进行一些小的更改,使所有尺寸至少对内容做出响应:
最重要的变化:
使用&#39; Calc&#39;设置宽度。支持是合理的(参见caniuse),但你也可以使用负边距(或者可能还有其他方式)来解决这个问题。
.infobox h3 {
width: calc(100% + 20px);
}
右箭头可以通过将right
设置为-12px
来解决,就像左边的left: -12px
一样。
.infobox-container .triangle-r {
right: -12px;
}
.infobox-container {
position: relative;
display: inline-block;
margin: 0;
padding: 0;
width: auto;
}
.infobox {
padding: 10px 5px 5px 5px;
margin:10px;

如果您希望此标题功能区具有响应性,则需要远离使用固定宽度,而是组合width:100%;
和max-width: 270px;
(或其他)。
当您将width属性定义为270px时,您告诉浏览器您希望此特定元素的最小和最大宽度均为270px。如果你正在思考,你真正想要的是你的元素尽可能地扩展(width:100%
),但是最大值为270px(max-width: 270px;
)。
这是响应位。
你真正追求的是更接近这一点:

我在这里做了一些事情:
* {box-sizing:border-box;}
,这使得元素“模具化”到我告诉他们的宽度(不论边距),more details here width:100%;max-width:500px;
。如果您尝试调整尺寸,则功能区会保持不动。
