防止背景重复 [英] Prevent Background Repeating

问题描述

如何防止背景重复?目前，它重复了两次，但是我需要背景来填满整个页面而不重复(因为否则看起来很奇怪！).下面是我的代码，但是如果需要，我可以提供一个网站链接.

How do I prevent a background from repeating? Currently it's repeated twice, but I need the background to fill the whole page without repeating (because otherwise it looks strange!). Below is my code, but I can provide a site link if needed.

HTML

<div class="container">
<img src="box.png" style="float: left;" />
<div class="navrow">
<ul>
<li class="navmenu" style="background: #6dc066;"><a href="index.php">Home</a></li>
<li class="navmenu" style="background: #a155e7;"><a href="about.php">About</a></li>
<li class="navmenu" onclick="shakeregister();" style="background: #ffa500;">Register</li>
<li class="navmenu" style="background: #3399ff;"><a href="play.php">Login</a></li>
<li class="navmenu" style="background: #ff6666; margin-right: 0px;"><a href="contact.php">Contact</a></li>
<div style="clear: left;"></div>
</ul>
</div>
<div style='clear:both'></div>
</div>

CSS

body {
 font-family: Titillium Web, sans-serif;
 background-image: url("images/polarvillebg.png");
}

h1, h2, h3 {
 font-weight: normal;
}

.container {
 width: 70%;
 margin: 0 auto;
 margin-top: 2%;
}

.navrow {
 float: right;
 text-align: center;
}

.navrow li {
 display: inline-block;
}

.navrow li a {
 color: #fff;
 text-decoration: none;
 width: 100%; 
 height: 100%;
 display: block;
}

.navmenu {
 height: 100px;
 width: 78px;
 color: #fff;
 margin-right: 4px;
 line-height: 100px;
 transition:height 0.5s; 
 -webkit-transition:height 0.5s; 
 box-shadow: rgb(204, 204, 204) 0px 0px 10px 0px;
 cursor: pointer;
}

.navmenu:hover {
 height: 107px;
}

推荐答案

CSS规则:

background-size: cover;

将使背景图像足够大，以使其覆盖背景元素.这还会产生不重复背景图像的副作用.

will make the background image large enough so that it covers the element that it's a background to. This will also have the side effect of not repeating the background image.

如果在此之后仍然无法进行背景重复，则可以使用:

If you're still having trouble with background repeating after that, you can use:

background-repeat: no-repeat;

明确要求背景不重复.

总而言之，在您提供的代码中，完整的解决方案是将您的 body 规则更改为此:

So all together, in the code you provided, the full solution would be to change your body rule to this:

body {
 font-family: Titillium Web, sans-serif;
 background-image: url("images/polarvillebg.png");
 background-size: cover;
 background-repeat: no-repeat;
}
