html - 在 css 中创建三 Angular 形

Question

如何在 CSS 中实现这一点。我用谷歌搜索，但没有找到任何解决方案。

Answer 1

试试这个:

HTML

<nav class="nav">
    <ul>
        <li><a href="#">1. Account Info</a></li>
        <li><a href="#">2. Verification</a></li>
        <li><a href="#">3. Enjoy</a></li>
    </ul>
</nav>

样式表

.nav ul {
    margin: 0;
    padding: 0;
    list-style: none;
    overflow: hidden;
    width: 100%;
}
.nav ul li {
    float: left;
    margin: 0 .2em 0 1em;
}
.nav ul a {
    background: red;
    padding: .3em 1em;
    float: left;
    text-decoration: none;
    color: #fff;
    position: relative;
}
.nav ul li:first-child a:before {
    content: normal;
}
.nav ul li:last-child a:after {
    content: normal;
}
.nav ul a:before {
    content: "";
    position: absolute;
    top: 50%;
    margin-top: -1.5em;
    border-width: 1.5em 0 1.5em 1em;
    border-style: solid;
    border-color: red rgba(0, 0, 0, 0);
    left: -1em;
    margin-left: 1px;
}
.nav ul a:after {
    content: "";
    position: absolute;
    top: 50%;
    margin-top: -1.5em;
    border-top: 1.5em solid rgba(0, 0, 0, 0);
    border-bottom: 1.5em solid rgba(0, 0, 0, 0);
    border-left: 1em solid red;
    right: -1em;
    margin-right: 1px;
}
