弯曲的按钮角落

我正在寻找创建这些按钮的选项:

Screenshot

目前,我已经能够通过创建一个圆形面具来实现所显示的效果,该面具位于徽标和背景下面,但在按钮上方。但是,这会在尝试将导航固定到顶部时引起问题。

是否可以在没有遮罩的情况下创建这样的按钮,可能使用border-radius?

这是我到目前为止所做的:



/* Navigation */

#logo {
  background-color: #f0f0f0;
  position: relative;
  height: 150px;
  width: 150px;
  margin: -172px auto;
  border: 6px solid #ffffff;
  border-radius: 200px;
  box-shadow: 2px 2px 5px 2px rgba(0, 0, 0, .04);
  z-index: 3;
}
#logo:active {

以下是我使用:before and :after pseudo elements对您的设计的看法以及所需的最低HTML。它使用了掩蔽概念,但它不会破坏。

Screenshot

曲线

使用导航的:after伪元素创建两个按钮上的曲线。在导航栏上使用overflow: hidden切断圆圈。它的位置为position: absolute,不会偏离其位置。

导航被赋予position: relative,以便圆圈将自己定位与其相关。

看起来像这样:

Mask

定位链接

使用填充将链接推开。没有伪元素掩码,它们看起来像这样:

Links Positioning

定位徽标

图像被赋予position: absolute并且位于left: 50%,宽度为负边距(包括边框),以使其处于死点。

标题为position: relative,以便徽标与其相关。

垂直居中

链接使用display: inline-blockvertical-align: middle进行居中。这要归功于:before伪元素垂直居中技巧。这会将内联元素排成一行,如下所示:

header nav:before {
    content: '';
    height: 100%;
    display: inline-block;
    vertical-align: middle;
}

文字使用line-height: 50px与链接height: 50px匹配的链接居中。

内联间隙

通过在内联元素之间不留空格来防止内联间隙,如下所示:

  <nav><a href="#">About</a><a href="#">Work</a></nav>

固定宽度

* {
  font-family: arial;
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}
header {
  background: #EEE;
  height: 80px;
  display: block;
  padding: 0 25px;
  position: relative;
  width: 377px;
}
header nav {
  height: 100%;
  position: relative;
  overflow: hidden;
}
header nav:before {
  content: '';
  height: 100%;
  display: inline-block;
  vertical-align: middle;
}
header nav:after {
  content: '';
  position: absolute;
  top: 0;
  left: 50%;
  width: 170px;
  height: 170px;
  margin-left: -85px;
  border-radius: 50%;
  background: #EEE;
}
header nav a {
  height: 50px;
  display: inline-block;
  background: #666;
  color: #FFF;
  text-decoration: none;
  font-weight: bold;
  line-height: 50px;
  padding: 0 10px 0;
  vertical-align: middle;
}
header nav a:first-child {
  padding: 0 100px 0 20px;
  border-radius: 3px 0 0 3px;
}
header nav a:last-child {
  padding: 0 20px 0 100px;
  border-radius: 0 3px 3px 0;
}
header img {
  position: absolute;
  top: 15px;
  left: 50%;
  margin-left: -70px;
  border-radius: 50%;
  border: solid 5px #FFF;
}
<header>
  <nav><a href="#">About</a><a href="#">Work</a></nav>
  <img src="http://www.placehold.it/130" />
</header>

100%宽度并居中

  • 而不是宽度,由于display: block(默认值),标题可以占据宽度的100%

  • 所有内容都位于标题内的text-align: center

100% width Screenshot

我会这样做:http://jsfiddle.net/56axt9z0/1/

您只需要重叠divborder-radius等于width / height一半的div来获得循环{{1}}
