大家好我以codepen为例在mysite上使用。我的问题是,当您点击不同的颜色时,在第五个面板上可以制作下拉框吗?

Html:

<link href='https://fonts.googleapis.com/css?family=Open+Sans:400,300,600|Source+Code+Pro' rel='stylesheet' type='text/css'>

<div class="patch-container">
  <div class="patch-item patch-button" data-patch-panel="1">One</div>
  <div class="patch-panel" data-patch-panel="1">One</div>
  <div class="patch-item patch-button" data-patch-panel="2">Two</div>
  <div class="patch-panel" data-patch-panel="2">Two</div>
  <div class="patch-item patch-button" data-patch-panel="3">Three</div>
  <div class="patch-panel" data-patch-panel="3">Three</div>
  <div class="patch-item patch-button wide" id="js-four" data-patch-panel="4">Four</div>
  <div class="patch-panel" data-patch-panel="4">Four</div>
  <div class="patch-item patch-button wide" id="js-five" data-patch-panel="5">Five</div>
  <div class="patch-panel" data-patch-panel="5">Five</div>
</div>

CSS:

*,
*:before,
*:after {
  box-sizing: border-box;
  -webkit-appearance: none;
}

body {
  height: 100%;
  background-color: #22313F;
  font-family: 'Open Sans';
  -webkit-font-smoothing: subpixel-antialiased;
}

.patch-button:hover {

.patch-container {

[data-patch-panel='1'],
[data-patch-panel='5'],
[data-patch-panel='8'] {
  background: #F5AB35;
}

[data-patch-panel='2'],
[data-patch-panel='6'],
[data-patch-panel='9'] {
  background: #00B16A;
}

[data-patch-panel='3'],
[data-patch-panel='7'],
[data-patch-panel='10'] {
  background: #E74C3C;
}

[data-patch-panel='4'],
[data-patch-panel='8'],
[data-patch-panel='12'] {

@media only screen and (min-width: 550px) {
  h2 {
    font-size: 3.3rem;
  }
  .patch-item {
    margin: 1%;
    width: 48%;
  }
  .patch-panel {
    margin: 1%;
    width: 98%;
  }
  .components {
    margin: 1.5%;
    width: 46%;
  }
}

@media only screen and (min-width: 992px) {
  .patch-container {
    margin: 4% auto;
  }
  .patch-item {
    margin: 0.6667%;
    margin: calc(4% / 6);
    width: 32%;
  }
  .patch-panel {
    margin: 0.6667%;
    margin: calc(4% / 6);
    width: 98.6666%;
    width: calc(100% - (4% / 6) * 2);
  }
  .resize {
    margin: 50px auto -2%;
  }
  .wide {
    margin: 0.6667%;
    margin: calc(4% / 6);
    width: 48.6666%;
    width: calc(50% - (4% / 6) * 2);
  }
  .thin {
    width: 23.6666%;
    width: calc(25% - (4% / 6) * 2);
  }
}

所以再说一遍,一切正常。但我想要发生的是在面板5.它自己的盒子很好,但是当你点击它时,我希望它不是橙色,而是出现在新盒子上的不同颜色。所以对于新的盒子出现,我希望它是白色的黑色边框,但我不知道如何

[data-patch-panel='1'],
[data-patch-panel='5'],
[data-patch-panel='8'] {
  background: #F5AB35;
}

尝试使用此部分,但这会影响这两个框。

感谢您的帮助

您希望为面板提供另一个类,ID或属性,以便在它上面的面板中识别它。像这样:

<div class="patch-panel panel-five" data-patch-panel="5">Five</div>

然后添加

.panel-five {
  background-color: #FFFFFF;
}
