我的问题是div的宽度。它以固定宽度来。但我想要它是自动的，基于内容的内容的长度，并能够增长到最大的宽度的80％。

My issue is the width of the div. It's coming as a fixed width. But I want it to be auto, based on the length of the content inside, and able to grow to a max of 80% of the width.

我使用两个类 .bubble-right 和 .bubble-left 使用边距对齐它们。

I'm using two classes .bubble-right and .bubble-left to align them using margins.

.bubble-left {
    margin-top: 1%;
    margin-right: 20%;
    position: relative;
    color: #000;
    padding: 5px 20px 5px 20px;
    background: #D5D9DB;
    -webkit-border-radius: 10px;
    -moz-border-radius: 10px;
    border-radius: 10px;
}
.bubble-left:after {
    content: '';
    position: absolute;
    border-style: solid;
    border-width: 12px 17px 12px 0;
    border-color: transparent #D5D9DB;
    display: block;
    width: 0;
    z-index: 1;
    margin-top: -12px;
    left: -17px;
    top: 60%;
}
.bubble-right {
    margin-top: 1%;
    position: relative;
    color: #fff;
    margin-left: 20%;
    padding: 5px 20px 5px 20px;
    background: #5EC979;
    -webkit-border-radius: 10px;
    -moz-border-radius: 10px;
    border-radius: 10px;
}
.bubble-right:after {
    content: '';
    position: absolute;
    border-style: solid;
    border-width: 12px 0 12px 17px;
    border-color: transparent #5EC979;
    display: block;
    width: 0;
    z-index: 1;
    margin-top: -12px;
    right: -17px;
    top: 60%;
}

当CSS float属性用于左右对齐<

我在寻找 a 。

推荐答案

你应该在.bubble-

You should add the background-color to the P inside your .bubble-(left|right)

IE：

.bubble-left, .bubble-right {
    position: relative;
    clear: both;
    padding: 0 17px;
    overflow: hidden;
    margin-top: 1%;
}

.bubble-left {
    margin-right: 20%;
}

.bubble-right {
    margin-left: 20%;
}

.bubble-left p, .bubble-right p {
    color: #000;
    padding: 5px 20px;
    line-height: 24px;
    -webkit-border-radius: 10px;
    -moz-border-radius: 10px;
    border-radius: 10px;
    width: auto;
    display:inline-block;
    margin: 0;
}

.bubble-left p {
    background: #D5D9DB;
    float: left;
}

.bubble-right p {
    background: #5EC979;
    float: right;
}

.bubble-left:after, .bubble-right:after {
    content: '';
    position: absolute;
    border-style: solid;
    display: block;
    width: 0;
    z-index: 1;
    margin-top: -12px;
    top: 50%;
}

.bubble-left:after {
    left: 0;
    border-width: 12px 17px 12px 0;
    border-color: transparent #D5D9DB;
}

.bubble-right:after {
    right: 0;
    border-width: 12px 0 12px 17px;
    border-color: transparent #5EC979;
}
