创建响应式html / css图像滑块

时间:2018-01-07 02:09:52

标签: html css

我的目标是让html / css滑块响应。目前,当宽度大约是标准iPhone的宽度时,滑块图像会对齐,因此从图像滑块下方开始的文本也是如此。我喜欢将滑块保持为一个单独的盒子"始终占据整个宽度,以便在缩放页面时文本不会跳转。我认为这可以通过将整个滑块元素包装在div中并将所述元素的宽度设置为100%来实现,但遗憾的是没有。

我现在尝试使用滑块图像,我最初的想法是使用百分比,因为我可以在所有6个空格之间设置4%的间隙,并且所有滑块图像的宽度为16%,但是当我向滑块添加百分比宽度时,它无法正确应用。

约束:我无法在外部css中加载(是的,使用bootstrap会很容易),我不能使用Javascrip。只有css和html。

我在鬼博客页面上这样做,因此有限制。

看看这里的代码:



<style>
* {
  margin: 0;
  padding: 0;
}

.slider {
  width: 100%;
  position: relative;
  padding-top: 48%;
  margin: 10px auto;
}

.slider>img {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  transition: all 0.2s;
}

.slider input[name^='slide_switch'] {
  display: none;
}

.slider label {
  margin: 4.6% 0 0 4.6%;
  border: 3px solid #999;
  float: left;
  cursor: pointer;
  transition: all 0.2s;
  opacity: 0.6;
}

.slider label img {
  display: block;
}

.slider input[name^='slide_switch']:checked+label {
  border-color: #666;
  opacity: 1;
}

.slider input[name^='slide_switch']~img {
  opacity: 0;
}

.slider input[name^='slide_switch']:checked+label+img {
  opacity: 1;
}
</style>

对于滑块标签,请尝试display: inline-block;而不是float: left;

.slider label {
    margin: 4.6% 0 0 4.6%;
    border: 3px solid #999;
    display: inline-block;
    cursor: pointer;
    transition: all 0.2s;
    opacity: 0.6;
}

由于float: left;导致下面的元素向右填充空格,因此根据情况可能会产生麻烦。

另一种选择是在样式表中添加一些css,将滑块元素设置为clear:both上的:after(这会删除后面元素的浮动效果。)

.slider:after {
    content: '';
    display: block;
    clear: both;
}

以下是display:block;float代替.slider label的示例:

* {
  margin: 0;
  padding: 0;
}

.slider {
  width: 100%;
  position: relative;
  padding-top: 48%;
  margin: 10px auto;
}

.slider>img {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  transition: all 0.2s;
}

.slider input[name^='slide_switch'] {
  display: none;
}

.slider label {
  margin: 4.6% 0 0 4.6%;
  border: 3px solid #999;
  display: inline-block;
  cursor: pointer;
  transition: all 0.2s;
  opacity: 0.6;
}

.slider label img {
  display: block;
}

.slider input[name^='slide_switch']:checked+label {
  border-color: #666;
  opacity: 1;
}

.slider input[name^='slide_switch']~img {
  opacity: 0;
}

.slider input[name^='slide_switch']:checked+label+img {
  opacity: 1;
}

你需要

.slider {
  overflow: hidden;
}

...让它扩展到包括它漂浮的孩子。否则,其高度将不包括浮动元素,使滑块填充标签周围的任何空格后的内容。

* {
  margin: 0;
  padding: 0;
}

.slider {
  width: 100%;
  position: relative;
  padding-top: 48%;
  margin: 10px auto;
  overflow: hidden;
}

.slider>img {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  transition: all 0.2s;
}

.slider input[name^='slide_switch'] {
  display: none;
}

.slider label {
  margin: 4.6% 0 0 4.6%;
  border: 3px solid #999;
  float: left;
  cursor: pointer;
  transition: all 0.2s;
  opacity: 0.6;
}

.slider label img {
  display: block;
}

.slider input[name^='slide_switch']:checked+label {
  border-color: #666;
  opacity: 1;
}

.slider input[name^='slide_switch']~img {
  opacity: 0;
}

.slider input[name^='slide_switch']:checked+label+img {

但是,在标签上使用float:left不是一个非常敏感的友好解决方案,因为它们不会以特定宽度为中心。我会选择一个flexbox解决方案来解决这个问题:

.slider {
  display: flex;
  flex-wrap: wrap;
  justify-content: center;
}
.slider label {
  margin: 4.6% 15px 0;
}

* {
  margin: 0;
  padding: 0;
}

.slider {
  width: 100%;
  position: relative;
  padding-top: 48%;
  margin: 10px auto;
  display: flex;
  flex-wrap: wrap;
  justify-content: center;
}

.slider>img {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  transition: all 0.2s;
}

.slider input[name^='slide_switch'] {
  display: none;
}

.slider label {
  margin: 4.6% 15px 0;
  border: 3px solid #999;
  cursor: pointer;
  transition: all 0.2s;

}

正确居中的另一个选择(如果您需要支持古老的浏览器)是在标签上使用display:inline-block;,从中移除float并将text-align: center添加到.slider

.slider {
  text-align: center;
}
.slider label {
  margin: 4.6% 15px 0;
  display: inline-block;
  /* don't forget to remove float:left; ! */
}

另外,在部署之前,请记住properly prefix CSS。在过滤器框中设置> 0%,以获得最大的浏览器兼容性。
