用CSS绘制三角形裁剪形状

Question

我必须在我的网站上做一个标志形状。设计如下。我该怎么发展呢？

​

​

对于徽标的第一部分，我使用CSS3斜交属性创建了它，我修改了下面的链接。如何开发三角形部分和标志的第三部分。三角形是滑块，所以里面的图像应该改变。

    .logo-menu {
        height: 76%;
        left: 11%;
        margin: 0 auto;
        width: 80%;
    }
    .first-part {
        display: inline-block;
        left: 135px;
        position: relative;
        transform: skew(-22deg);
        width: 180px;
    }
    .menu-1{
        background:red
    }
    .menu-2{
        background:blue
    }
    .menu-3{
        background:yellow
    }

    <div class="logo-menu">
    <div class="first-part">
        <div class="menu-1" style="height: 167px;">
             <h3>About Us</h3>
        </div>
        <div class="menu-2" style="height: 167px;">
             <h3>Gallery</h3>
        </div>
        <div class="menu-3" style="height: 167px;">
             <h3>Get in Touch with</h3>
        </div>

Answer 1

您可以使用CSS转换将元素旋转和倾斜为菱形，然后为子元素反转这些转换。如果在钻石上有overflow: hidden;，并将钻石放置在也有overflow: hidden;的包装中，则可以使用CSS生成一个包含内容的裁剪三角形。

工作示例(科德芬)：

​

/* Clip the bottom half of the diamond. */
.triangle-wrap {
	width: 400px;
	height: 400px;
	position: relative;
	overflow: hidden;
}
/* Rotate and skew to create a diamond. */
.triangle {
	background: grey;
	position: absolute;
	bottom: -50%;
	width: 100%;
	height: 100%;
	overflow: hidden;
	-webkit-transform: rotate(45deg) skew(20deg, 20deg);
	   -moz-transform: rotate(45deg) skew(20deg, 20deg);
	    -ms-transform: rotate(45deg) skew(20deg, 20deg);
	        transform: rotate(45deg) skew(20deg, 20deg);
}
/* Reset the skew and rotation. */
.triangle-reset {
	width: 100%;
	height: 100%;
	position: relative;
	-webkit-transform: skew(-20deg, -20deg) rotate(-45deg);
	   -moz-transform: skew(-20deg, -20deg) rotate(-45deg);
	    -ms-transform: skew(-20deg, -20deg) rotate(-45deg);
	        transform: skew(-20deg, -20deg) rotate(-45deg);
}
/* Create a content wrapper. */
.triangle-content {
	background: url('http://placehold.it/400x400') no-repeat;
	background-position: center center;
	background-size: cover;
	position: relative;
	width: 120%;
	height: 120%;
	left: -10%;
	bottom: 65%;
}

/* Visual aid. */
html {
	min-height: 100%;
	background: linear-gradient(to bottom, #336666 0%,#663366 100%);
}

<div class="triangle-wrap">
	<div class="triangle">
		<div class="triangle-reset">
			<div class="triangle-content">
			</div>
		</div>
	</div>
</div>

background-clip是你要找的东西。看看这篇伟大的文章：

下面是一个帮助您生成形状的在线工具：

生成每个形状后，您可以将它们定位为像您的图像。

你想要的不是完美的，而是接近它的。右边第一副看起来不太好。
