我刚刚注意到有关项目滑块Article from codrops的这篇精彩文章：此演示可在此处Demo of the article "How to Create a Simple Multi-Item Slider"

我想在我的网站上实现相同的功能，只需进行一些更改。

项目的显示由三个主文件组成：

HTML 

		<div class="container">	
			<header>
				<h1>Simple Multi-Item Slider <span>Category slider with CSS animations</span></h1>
			</header>
			<div class="main">
				<div id="mi-slider" class="mi-slider">
					<ul>
						<li><a href="#"><img src="images/1.jpg" alt="img01"><h4>Boots</h4></a></li>
						<li><a href="#"><img src="images/2.jpg" alt="img02"><h4>Oxfords</h4></a></li>
						<li><a href="#"><img src="images/3.jpg" alt="img03"><h4>Loafers</h4></a></li>
						<li><a href="#"><img src="images/4.jpg" alt="img04"><h4>Sneakers</h4></a></li>
					</ul>
					<ul>
						<li><a href="#"><img src="images/5.jpg" alt="img05"><h4>Belts</h4></a></li>
						<li><a href="#"><img src="images/6.jpg" alt="img06"><h4>Hats &amp; Caps</h4></a></li>

						<li><a href="#"><img src="images/15.jpg" alt="img15"><h4>Briefcases</h4></a></li>
					</ul>
					<nav>
						<a href="#">Shoes</a>
						<a href="#">Accessories</a>
						<a href="#">Watches</a>
						<a href="#">Bags</a>
					</nav>
				</div>

我要做的是从demo.css文件中删除以下代码并将其应用于需要它的特定元素，而不是将其应用于所有内容。保留此代码对我的网站显示有一些影响，但当我删除它时，它也会影响滑动项目：

*,
*:after,
*:before {
	-webkit-box-sizing: border-box;
	-moz-box-sizing: border-box;
	box-sizing: border-box;
	padding: 0;
	margin: 0;
}

问题是，我不知道使用该代码的元素以及为什么它对滑动项有一些影响。

请告诉我如何解决这个问题。

正如我在其他帖子中所承诺的，这是我对你的问题的帮助。

有问题的代码（如下所示）实际上是一种强制浏览器使用旧border-box模式而不是默认content-box的黑客/修正。

*,
*:after,
*:before {
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    padding: 0;
    margin: 0;
}

两种模式有什么区别？在border-box模式下，元素的宽度/高度组合了内容，填充和边框的宽度/高度。在content-box模式中，元素的宽度/高度仅与其内容有关。来源：developer.mozilla.org。

简而言之，您可以安全地删除有问题的CSS块。 然而，这会导致某些项目变大。

为了获得相同的外观，您必须找出所有设置width或height 以及 padding或{{{ 1}}。在这些情况下，只需将以下行添加到块中：

border

但是，经过进一步检查，我发现-webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; 仅用于演示，可以完全删除。您可以在demo.css。

中指定多项目滑块所需的全部内容

基本上，星号会导致CSS应用于您网站上的所有内容。您可以通过一些试验和错误来解决问题。只需将星号与似乎适用的类交换即可。只是从查看代码，它似乎是.mi-slider，但是也可能有一些额外的类。你只有一些课程，所以不用花太长时间才能弄清楚究竟要使用哪些课程。

＆＃13;
＆＃13; 
.mi-slider,
.mi-slider:after,
.mi-slider:before {
	-webkit-box-sizing: border-box;
	-moz-box-sizing: border-box;
	box-sizing: border-box;
	padding: 0;
	margin: 0;
}
＆＃13;
＆＃13;
