屏幕宽度拉伸时自动增加边距

问题描述 投票:9回答:3

我有一个列表(<ul />),我尝试显示为网格。单元格具有固定的宽度(比如100px):列和行的数量取决于屏幕分辨率。

当屏幕宽度很大时,有很多列但很少行:

   ______________________________________________________________
  |   ___________    ___________    ___________    ___________   |
  |  |           |  |           |  |           |  |           |  |
  |  |    #1     |  |    #2     |  |    #3     |  |    #4     |  |
  |  |<- 100px ->|  |<- 100px ->|  |<- 100px ->|  |<- 100px ->|  |
  |  |           |  |           |  |           |  |           |  |
  |  |___________|  |___________|  |___________|  |___________|  |
  |   ___________                                                |
  |  |           |                                               |
  |  |    #5     |                                               |
  |  |<- 100px ->|                                               |
  |  |           |                                               |
  |  |___________|                                               |
  |______________________________________________________________|

当屏幕宽度较小时,列数很少但行数很多:

               ________________________________
              |   ___________    ___________   |
              |  |           |  |           |  |
              |  |    #1     |  |    #2     |  |
              |  |<- 100px ->|  |<- 100px ->|  |
              |  |           |  |           |  |
              |  |___________|  |___________|  |
              |   ___________    ___________   |
              |  |           |  |           |  |
              |  |    #3     |  |    #4     |  |
              |  |<- 100px ->|  |<- 100px ->|  |
              |  |           |  |           |  |
              |  |___________|  |___________|  |
              |   ___________                  |
              |  |           |                 |
              |  |    #5     |                 |
              |  |<- 100px ->|                 |
              |  |           |                 |
              |  |___________|                 |
              |________________________________|

这实际上几乎是有效的:看到这个fiddle

几乎,因为您可以注意到,当您拉伸宽度时,网格右侧可能会出现一个空白区域。这是因为float: left CSS属性,并且是可以理解的。

但是,有没有办法在单元格之间分配这个空白区域,即自动增加单元格之间的边距,直到有足够的空间来容纳新单元格?

换句话说,目前有15px的固定余量,我正在寻找一种15px的最小边距,在拉伸宽度时自动增长,并且一旦新单元符合第一行,则返回到15px 。

为了说明,而不是:

请注意,第二个插图中的边距较大,因此不再有空格。

有什么解决方案吗?

请注意,#5单元格也必须左对齐,即align-center CSS属性不符合我的需要(据我所知)。

此外,我将使用jQuery 1.10和Bootstrap 3,因此欢迎使用这些库中的一个(或多个)的任何解决方案;)

我创建了一个jQuery脚本来修复你的问题。看到这个fiddle。我编写了脚本,你根本不需要改变它。您只需将最小边距设置为CSS中的边距,并添加所需数量的<li>元素。

function setMargin() {
  ulWidth = $('ul').innerWidth();
  boxWidth = $('li').outerWidth();
  boxMargin = parseInt($('li').css('margin'));
  maxBoxNum = $("ul li").length;
  boxNum = Math.floor((ulWidth / (boxWidth + boxMargin)));
  totalMargin = ulWidth - (boxNum * boxWidth);
  eachMargin = totalMargin / (boxNum + 1);
  if (eachMargin < boxMargin) {
    boxNum -= 1;
    totalMargin = ulWidth - (boxNum * boxWidth);
    eachMargin = totalMargin / (boxNum + 1);
  }
  if (boxNum > maxBoxNum) {
    boxNum = maxBoxNum;
    totalMargin = ulWidth - (boxNum * boxWidth);
    eachMargin = totalMargin / (boxNum + 1);
  }
  $('li').css('margin-left', eachMargin);
}

$(document).ready(function() {
  setMargin();
});

$(window).resize(function() {
  setMargin();
});
ul {
  margin: 0;
  padding: 0;
  list-style-type: none;
}

li {
  width: 100px;
  height: 100px;
  margin: 15px 0;
  padding: 0;
  border: solid 1px black;
  display: inline-block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<ul>
  <li>#1</li>
  <li>#2</li>
  <li>#3</li>
  <li>#4</li>
  <li>#5</li>
</ul>

如果你可以使用百分比宽度并知道网格单元格超过3 - 最好的方法是使用像this fiddle这样的媒体查询。您将通过单元格大小增加填充空边距。

您只需使用CSS即可实现目标。我在谈论媒体查询。这是我制作的DEMO。它表明你可以使用计算来定位你的方块之间相等的边距。元素和窗口之间的边距也是相同的。

我没有为751px以上的屏幕编写代码但是你明白了。这是代码:

html,
body {
  margin: 0;
  padding: 0;
  min-width: 150px;
}

.wrap {
  float: left;
  position: relative;
}

.foto {
  width: 150px;
  height: 150px;
  background: gold;
  position: absolute;
}

#warning {
  display: none;
}

@media screen and (min-width: 631px) {
  .wrap {
    width: 20%;
    padding-bottom: 25%;
  }
  .wrap:nth-child(4n+2),
  .wrap:nth-child(4n+3) {}
  .wrap .foto {
    top: -75px;
    margin-top: 100%;
    right: -30px;
  }
  .wrap:nth-child(4n+2) {
    margin: 0 5% 0 7.5%;
  }
  .wrap:nth-child(4n+3) {
    margin-right: 7.5%;
  }
  .wrap:nth-child(4n+2) .foto {
    left: 50%;
    margin-left: -75px;
  }
  .wrap:nth-child(4n+3) .foto {
    right: 50%;
    margin-right: -75px;
  }
  .wrap:nth-child(4n) .foto {
