我目前有两张图片,我想对它们应用滤镜或渐变:
HTML:
<div class='category_a tinted'>
</div>
<div class='category_b tinted'>
</div>
的CSS:
.category_a{
background-image : url(...);
}
.category_b{
background-image : url(...);
}
.tinted{
background: linear-gradient(rgba(0,0,0,0.5), rgba(0,0,0,0.5), 100%);
}
但是,它的背景会覆盖background-image属性。如何同时获得色调和图像(不重复代码)。

background-image: url(), gradient-goes-here
试试这个。它会工作
background-image: url(IMAGE), linear-gradient(...Color You Want...)

要扩展@ChronixPsyc点,附加到单独类的伪元素将实现此目的。
如果div有内容,您可能会遇到z-index
的问题,但这可以修复。
[class*="category"] {
width: 100px;
height: 100px;
display: inline-block;
border:1px solid red;
margin: 25px;
}
.tinted > * {
position: relative; /* required to 'set' z-index */
}
h2 {
color: white;
text-align: center;
}
.category_a {
background-image: url(http://lorempixel.com/100/100/sports/1/);
}
.category_b {
background-image: url(http://lorempixel.com/100/100/sports/2/);
}
.tinted {
position: relative; /* positioning context */
}
.tinted::before {
content:"";
position: absolute;
width: 100%;
height: 100%;
top:0;
left:0;
background-image: linear-gradient(to bottom, rgba(255,0,0,0.5), rgba(0,0,0,0.5));
}
<div class="category_a tinted">
<h2>Caption</h2>>
</div>
<div class="category_b tinted">
<h2>Caption</h2>>
</div>

如果您使用的是LESS,请尝试以下内容:
.category_a:after {
content:"";
.tinted; // class with your background;
position:absolute;
// Add your top, bottom, left, right here
z-index:1;
}
或者,如果您不使用LESS,请尝试此
.category_a:after {
content:"";
position:absolute;
// Add your top, bottom, left, right here
background: linear-gradient(rgba(0,0,0,0.5), rgba(0,0,0,0.5)), 100%);
z-index:1;
}
