问题描述

我要放置在一个℃的梯度; IMG> 标记。 标记的SRC 属性是角项目。例如:
< IMG SRC = {{value.angitem.image}}>

我试图让CSS类:

  .pickgradient {
    背景:-webkit-梯度(线性,左上角,左下角,颜色停止(0%,RGBA(0,0,0,0)),彩站(100%,RGBA(0,0,0,0.65 )));
}

 < IMG SRC = {{value.angitem.image}}类=pickgradient>

,但它不工作。我应该怎么办?


解决方案

用z-index:

您可以使用一个容器,把梯度容器上。然后使用负的z-index定位图片渐变背后

\r
\r

.pickgradient {\r
  显示:inline-block的;\r
  背景:-moz线性梯度(顶,RGBA(0,0,0,0)0%,RGBA(0,0,0,0.65)100%); / * FF3.6 + * /\r
  背景:-webkit-梯度(线性,左上角,左下角,颜色停止(0%,RGBA(0,0,0,0.65)),彩站(100%,RGBA(0,0,0,0 ))); / *铬,Safari4 + * /\r
  背景:-webkit线性梯度(顶,RGBA(0,0,0,0)0%,RGBA(0,0,0,0.65)100%); / * Chrome10 +,Safari5.1 + * /\r
  背景:-o-线性梯度(顶,RGBA(0,0,0,0)0%,RGBA(0,0,0,0.65)100%); / *歌剧11.10+ * /\r
  背景:-ms线性梯度(顶,RGBA(0,0,0,0)0%,RGBA(0,0,0,0.65)100%); / * IE10 + * /\r
  背景:线性梯度(上下,RGBA(0,0,0,0)0%,RGBA(0,0,0,0.65)100%); / * * W3C /\r
  过滤:进程id:DXImageTransform.Microsoft.gradient(startColorstr ='#a6000000',endColorstr =#00000000,GradientType = 0); / * * IE6-9 /\r
}\r
\r
IMG {\r
  位置:相对;\r
  的z-index:-1;\r
  显示:块;\r
}

\r

< D​​IV CLASS =pickgradient>\r
  &所述; IMG SRC =htt​​p://lorempixel.com/image_output/people-q-c-640-480-9.jpg/>\r
< / DIV>

与伪元素:

至于评论,你也可以使用一个伪元素与梯度和绝对定位将在梯度图像

\r
\r

.pickgradient {\r
  位置:相对;\r
  显示:inline-block的;\r
}\r
.pickgradient:{后\r
  内容:'';\r
  位置:绝对的;\r
  左:0;顶部:0;\r
  宽度:100%;高度:100%;\r
  显示:inline-block的;\r
  背景:-moz线性梯度(顶,RGBA(0,0,0,0)0%,RGBA(0,0,0,0.65)100%); / * FF3.6 + * /\r
  背景:-webkit-梯度(线性,左上角,左下角,颜色停止(0%,RGBA(0,0,0,0.65)),彩站(100%,RGBA(0,0,0,0 ))); / *铬,Safari4 + * /\r
  背景:-webkit线性梯度(顶,RGBA(0,0,0,0)0%,RGBA(0,0,0,0.65)100%); / * Chrome10 +,Safari5.1 + * /\r
  背景:-o-线性梯度(顶,RGBA(0,0,0,0)0%,RGBA(0,0,0,0.65)100%); / *歌剧11.10+ * /\r
  背景:-ms线性梯度(顶,RGBA(0,0,0,0)0%,RGBA(0,0,0,0.65)100%); / * IE10 + * /\r
  背景:线性梯度(上下,RGBA(0,0,0,0)0%,RGBA(0,0,0,0.65)100%); / * * W3C /\r
  过滤:进程id:DXImageTransform.Microsoft.gradient(startColorstr ='#a6000000',endColorstr =#00000000,GradientType = 0); / * * IE6-9 /\r
}\r

I want to place a gradient over an <img> tag. src attribute of the tag is angular-item. For example: <img src={{value.angitem.image}}>

I've tried to make css class:

.pickgradient {
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(0,0,0,0)), color-stop(100%,rgba(0,0,0,0.65)));
}

and

<img src={{value.angitem.image}} class="pickgradient ">

but it doesn't work. What should I do?

解决方案

With z-index :

You may use a container and put the gradient on that container. Then use a negative z-index to position image behind the gradient.

.pickgradient {
  display:inline-block;
  background: -moz-linear-gradient(top, rgba(0,0,0,0) 0%, rgba(0,0,0,0.65) 100%); /* FF3.6+ */
  background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(0,0,0,0.65)), color-stop(100%,rgba(0,0,0,0))); /* Chrome,Safari4+ */
  background: -webkit-linear-gradient(top, rgba(0,0,0,0) 0%,rgba(0,0,0,0.65) 100%); /* Chrome10+,Safari5.1+ */
  background: -o-linear-gradient(top, rgba(0,0,0,0) 0%,rgba(0,0,0,0.65) 100%); /* Opera 11.10+ */
  background: -ms-linear-gradient(top, rgba(0,0,0,0) 0%,rgba(0,0,0,0.65) 100%); /* IE10+ */
  background: linear-gradient(to bottom, rgba(0,0,0,0) 0%,rgba(0,0,0,0.65) 100%); /* W3C */
  filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#a6000000', endColorstr='#00000000',GradientType=0 ); /* IE6-9 */
}

img{
  position:relative;
  z-index:-1;
  display:block;
}

<div class="pickgradient">
  <img src="http://lorempixel.com/image_output/people-q-c-640-480-9.jpg" />
</div>


With a pseudo element :

As commented, you can also use a pseudo element with the gradient and absolute positioning to put the gradient over the image :

.pickgradient{
  position:relative;
  display:inline-block;
}
.pickgradient:after {
  content:'';
  position:absolute;
  left:0; top:0;
  width:100%; height:100%;
  display:inline-block;
  background: -moz-linear-gradient(top, rgba(0,0,0,0) 0%, rgba(0,0,0,0.65) 100%); /* FF3.6+ */
  background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(0,0,0,0.65)), color-stop(100%,rgba(0,0,0,0))); /* Chrome,Safari4+ */
  background: -webkit-linear-gradient(top, rgba(0,0,0,0) 0%,rgba(0,0,0,0.65) 100%); /* Chrome10+,Safari5.1+ */
  background: -o-linear-gradient(top, rgba(0,0,0,0) 0%,rgba(0,0,0,0.65) 100%); /* Opera 11.10+ */
  background: -ms-linear-gradient(top, rgba(0,0,0,0) 0%,rgba(0,0,0,0.65) 100%); /* IE10+ */
  background: linear-gradient(to bottom, rgba(0,0,0,0) 0%,rgba(0,0,0,0.65) 100%); /* W3C */
  filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#a6000000', endColorstr='#00000000',GradientType=0 ); /* IE6-9 */
}

img{
  display:block;
}

<div class="pickgradient">
  <img src="http://lorempixel.com/image_output/people-q-c-640-480-9.jpg" />
</div>
