我正在尝试使用CSS生成下面的渐变图像。但是,我正在努力调整。您会在我的摘要中注意到该问题。我尝试绝对定位它们,但这只会使情况变得更糟。
.gradients {
position: relative;
width: 100%;
}
.gradients div {
height: 40px;
}
.bottom-gradient {
-ms-transform: rotate(0.6deg);
-webkit-transform: rotate(0.6deg);
transform: rotate(0.6deg);
background: -moz-linear-gradient(left, rgba(37, 52, 47, 0.9) 0%, rgba(3, 95, 26, 0.9) 100%);
background: -webkit-gradient(linear, left top, right top, color-stop(0%, rgba(37, 52, 47, 0.9)), color-stop(100%, rgba(3, 95, 26, 0.9)));
background: -webkit-linear-gradient(left, rgba(37, 52, 47, 0.9) 0%, rgba(3, 95, 26, 0.9) 100%);
background: -o-linear-gradient(left, rgba(37, 52, 47, 0.9) 0%, rgba(3, 95, 26, 0.9) 100%);

filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#80414c46', endColorstr='#80035f1a', GradientType=1);
}
.top-gradient {
-ms-transform: rotate(0.6deg);

答案 0 :(得分:1)
position: absolute
或负数margin
都可以,但是需要硬编码的值。一种更灵活的选择是将transform: translateY(-100%)
添加到您的.bottom-gradient
中。
由于该元素上已有transform: rotate(0.6deg)
,因此可以将translateY
附加到该元素上:
.bottom-gradient { transform: rotate(0.6deg) translateY(-100%) }
为了使图像更接近一点,我还做了以下更改:
rotation
更改为1deg
和-1deg
。height
更改为16px
;
.gradients {
position: relative;
width: 100%;
}
.gradients div {
height: 16px;
}
.bottom-gradient {
-ms-transform: rotate(-1deg) translateY(-100%);
-webkit-transform: rotate(-1deg) translateY(-100%);
transform: rotate(-1deg) translateY(-100%);
background: -moz-linear-gradient(left, rgba(37, 52, 47, 0.9) 0%, rgba(3, 95, 26, 0.9) 100%);
background: -webkit-gradient(linear, left top, right top, color-stop(0%, rgba(37, 52, 47, 0.9)), color-stop(100%, rgba(3, 95, 26, 0.9)));
background: -webkit-linear-gradient(left, rgba(37, 52, 47, 0.9) 0%, rgba(3, 95, 26, 0.9) 100%);
background: -o-linear-gradient(left, rgba(37, 52, 47, 0.9) 0%, rgba(3, 95, 26, 0.9) 100%);
background: -ms-linear-gradient(left, rgba(37, 52, 47, 0.9) 0%, rgba(3, 95, 26, 0.9) 100%);
background: linear-gradient(to right, rgba(37, 52, 47, 0.9) 0%, rgba(3, 95, 26, 0.9) 100%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#80414c46', endColorstr='#80035f1a', GradientType=1);
}
.top-gradient {
-ms-transform: rotate(1deg);
-webkit-transform: rotate(1deg);
transform: rotate(1deg);
background: -moz-linear-gradient(left, rgba(3, 95, 26, 0.9) 0%, rgba(37, 52, 47, 0.9) 100%);
background: -webkit-gradient(linear, left top, right top, color-stop(0%, rgba(3, 95, 26, 0.9)), color-stop(100%, rgba(37, 52, 47, 0.9)));
background: -webkit-linear-gradient(left, rgba(3, 95, 26, 0.9) 0%, rgba(37, 52, 47, 0.9) 100%);
background: -o-linear-gradient(left, rgba(3, 95, 26, 0.9) 0%, rgba(37, 52, 47, 0.9) 100%);
background: -ms-linear-gradient(left, rgba(3, 95, 26, 0.9) 0%, rgba(37, 52, 47, 0.9) 100%);
background: linear-gradient(to right, rgba(3, 95, 26, 0.9) 0%, rgba(37, 52, 47, 0.9) 100%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#80035f1a', endColorstr='#80414c46', GradientType=1);
}
<div class="gradients">
<div class="top-gradient"></div>
<div class="bottom-gradient"></div>
</div>

您可以仅使用伪元素并定义一次梯度来优化代码。
.gradients {
position: relative;
height: 40px;
margin:40px 0;
}
.gradients:before,
.gradients:after{
content:"";
position:absolute;
top:0;
left:0;
right:0;
bottom:0;
transform: rotate(2deg);
background: linear-gradient(to right, rgba(37, 52, 47, 0.9), rgba(3, 95, 26, 0.9));
}
.gradients:after {
/* since it's the same gradient in the other direction, you can simply make a mirror image of it*/
transform:scaleX(-1) rotate(2deg);
}
<div class="gradients">
</div>
您也可以考虑使用skew()
而不是旋转以获得可能更接近您想要的效果。注意边缘的不同:
.gradients {
position: relative;
height: 40px;
margin:40px 0;
}
.gradients:before,
.gradients:after{
content:"";
position:absolute;
top:0;
left:0;
right:0;
bottom:0;
transform: skewY(2deg);
background: linear-gradient(to right, rgba(37, 52, 47, 0.9), rgba(3, 95, 26, 0.9));
}
.gradients:after {
/* since it's the same gradient in the other direction, you can simply make a mirror image of it*/
transform:scaleX(-1) skewY(2deg);
}
<div class="gradients">
</div>
我还怀疑您想让某些东西响应,这意味着在调整窗口大小时,两个渐变之间的距离不应改变(上述解决方案并非如此)。为此,这是一个依赖SVG和背景的想法:
.gradients {
position: relative;
height: 80px;
margin:40px 0;
background-image: url('data:image/svg+xml;charset=UTF-8,<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" preserveAspectRatio="none" viewBox="0 0 25 30" ><defs><linearGradient id="one" ><stop offset="0%" stop-color="rgba(37, 52, 47, 0.9)"/><stop offset="100%" stop-color="rgba(3, 95, 26, 0.9)" /></linearGradient><linearGradient id="two" ><stop offset="0%" stop-color="rgba(3, 95, 26, 0.9)" /><stop offset="100%" stop-color="rgba(37, 52, 47, 0.9)"/></linearGradient></defs><polygon points="25,7 25,25 0,18 0,0" fill="url(%23one)"/><polygon points="25,0 25,18 0,25 0,7" fill="url(%23two)"/></svg>');
background-size:100%;
}
<div class="gradients">
</div>
以下是SVG的代码,它们用不同的颜色扩展以更好地理解:
svg {
width:100%;
height:100px;
}
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" preserveAspectRatio="none" viewBox="0 0 25 30">
<defs>
<linearGradient id="one" >
<stop offset="0%" stop-color="blue"/>
<stop offset="100%" stop-color="red" />
</linearGradient>
<linearGradient id="two" >
<stop offset="0%" stop-color="yellow" />
<stop offset="100%" stop-color="purple"/>
</linearGradient>
</defs>
<!-- update the value 7 and 18 by keeping it the same between both polygon -->
<polygon points="25,7 25,25 0, 18 0, 0" fill="url(#one)"/>
<polygon points="0, 7 0, 25 25,18 25,0" fill="url(#two)"/>
</svg>
