只有 css3 才有可能？

Answer 1

用一个元素你就可以做到这一点我必须去上班希望这有帮助

<div>Lorem Ipsum</div> 

风格：

   div{
        width:200px;
        height:60px;
        margin:100px;
        background-color:transparent;
        color:black;
        position:relative;
        text-indent:30px;
        line-height:60px;
        box-shadow:inset 20px 0 0 200px white;
        overflow:hidden;
        -webkit-box-shadow: inset -164px 0 0 20px white;
        -moz-box-shadow: inset -164px 0 0 20px white;
        box-shadow: inset -164px 0 0 20px white;
    }
    div:before{
        content: '';
    position: absolute;
    left: 0px;
    top: 4px;
    width: 14px;

        background-color:white;
    -webkit-transform: skew(0deg,34deg);
        -moz-transform: skew(0deg,34deg);

    transform: skew(0deg,-34deg);
    }
    body{

    background-image: -webkit-gradient(linear, left top, right bottom, color-stop(.25, rgba(255, 255, 255, .15)), color-stop(.25, transparent), color-stop(.5, transparent), color-stop(.5, rgba(255, 255, 255, .15)), color-stop(.75, rgba(255, 255, 255, .15)), color-stop(.75, transparent), to(transparent));

        width:100%;
        height:100%;

    }

背景不是实心的，这使得它很硬。 特别是因为你的箭头不是 90 度，我猜这不会变得那么平滑。 但是看看这个问题：

Answer 3

使用创建带有 div 透明边框的三角形的技术。 两次尝试可能会对您有所帮助，

HTML

<div class="button">
    <div class="wrapper">
        <div class=" top-side "></div>
        <div class="arrow-right "></div>
        <div class="arrow-right2 "></div>
        <div class="bottom-side "></div>
    </div>
</div>

CSS

.button {
    width: 400px;
    background-color:orange;
}
.wrapper{
    background-color:blue;
    width:2px;
}
.arrow-right {
    width: 0;
    height: 0;
    border-top: 5px solid transparent;
    border-bottom: 5px solid transparent;
    border-left: 15px solid white;
    position:absolute;
    z-index:2;
}
.arrow-right2 {
    position:relative;
    top:-1px;
    z-index:1;
    width: 0;
    height: 0;
    border-top: 6px solid transparent;
    border-bottom: 6px solid transparent;
    border-left: 18px solid blue;
}
.top-side {
    height:7px;
    width:2px;
    background-color:blue;
}
.bottom-side {
    height:7px;
    width:2px;
    background-color:blue;
}

这是@kougiland 的简化版本。

div {
    width:200px;
    height:60px;
    position:relative;
    text-indent:30px;
    line-height:60px;
}
div:before{
    content: '';
    position: absolute;
    top: 14px;
    left: 0px;
    width: 17px;
    border-bottom: 1px solid blue;
    border-left: 1px solid blue;
    -webkit-transform: skew(0deg,60deg);
    -moz-transform: skew(0deg,60deg);
    transform: skew(0deg,60deg);
}
div:after{
    content: '';
    position: absolute;
    left: 0px;
    bottom: 14px;
    width: 17px;
    border-top: 1px solid blue;
    border-left: 1px solid blue;
    -webkit-transform: skew(0deg,-60deg);
    -moz-transform: skew(0deg,-60deg);
    transform: skew(0deg,-60deg);
}
