如何添加“光泽"叠加到div? [英] How to add 'shine' overlay to a div?

问题描述

如何添加下图所示的漂亮叠加层?

How can I add a nice overlay like the one in the following image?

考虑以下HTML，我该如何添加一个叠加层?我知道我可以在其顶部使用渐变，然后对角地应用它，但是我也可以将其弯曲吗?

Consider the following HTML, how would I add an overlay like that? I know I can use a gradient on top of it, and apply it diagonally, but can I curve it as well?

<div class="photostrip">
  <div class="overlay" />
  <img src="http://i.imgur.com/a21tM.jpg" />
  <img src="http://i.imgur.com/a21tM.jpg" />
  <img src="http://i.imgur.com/a21tM.jpg" />
</div>

这里是我尝试过的东西(我已经使覆盖层过饱和，因此很容易看到)，但它并不是我想要的形状.

Here's something I've tried (I've oversaturated the overlay so it's easily seen), but it's not quite the shape I'm looking for.

body { background-color: #4b74db; }

.photostrip {
  margin: 0 auto;
  width: 185px;
  background-color: #000;  
  box-shadow: 0px 3px 7px 3px #333;
  padding: 7px;
  padding-bottom: 2px;
  position: relative;

  .overlay {
    height: 100%;
    width: 100%;
    position: absolute;
    top: 0px;
    left: 0px;
    border-bottom-right-radius: 200px 403px;
    /* This adds the nice overlay. */
  background: -webkit-linear-gradient(top, rgba(255,255,255,0.60) 0%,rgba(255,255,255,0.05) 100%);
  }


  img {
    display: block;    
    width: 175px;
    height: 120px;
    margin: 0 auto;
    margin-top: 6px;
    margin-bottom: 11px;
  }
}

这样对您有用吗? http://codepen.io/defo550/pen/Fcsxo

.photostrip {
  margin: 0 auto;
  width: 185px;
  background-color: #fff;  
  box-shadow: 0px 3px 7px 3px #333;
  padding: 7px;
  padding-bottom: 2px;

  /* Remove default list stylings*/
  list-style: none;

  /* provide a position context for our   pseudo element */
  li {
    position: relative;
  }

  img {
    display: block;  
    width: 175px;
    height: 120px;
    margin: 0 auto;
    margin-top: 6px;
    margin-bottom: 11px;
  }
}

/* overlay styles
  create pseudo element  
*/
.photostrip li:after {
        content: "";
        position: absolute;
       /* position above img */
        z-index: 5;

        width: 175px;
        height: 120px;
        top: 0;
        left: 5px;

/* overlay styles */
        background: linear-gradient(135deg, rgba(255,255,255,0.33) 0%,rgba(255,255,255,0.33) 60%,rgba(255,255,255,0) 61%,rgba(255,255,255,0) 100%);
      }

<ul class="photostrip">
 <li><img /></li>
 <li><img /></li>
 <li><img /></li>
</ul>

我将您的图像放在无序列表中，然后在li(创建每个图像)上创建了一个伪元素，该元素具有背景渐变，并且具有您上面图像的所需效果(或关闭).

I put your images in an unordered list and then created a pseudo-element on the li (that wraps each image) that has a background gradient with the desired effect ( or close ) of your image above.

您还可以在CSS中分别定位每个li以改变背景渐变.

You could also target each li separately in the CSS to change up the background gradient.
