[英]Height 100% not working properly while resizing browser
I am having Issue in using height . 我在使用height时遇到问题。 I have used height:100% for a div in my page. 我在页面中使用了height:100%作为div。 And I set a background color for that. 我为此设置了背景色。 It works fine while the browser is maximised. 当浏览器最大化时,它可以正常工作。 But when it is resized my div is not rendered properly. 但是,当调整大小时,我的div无法正确呈现。
My problem is when I resize the browser window , a scroll appears for my div but the background color is not rendered for my whole div. 我的问题是,当我调整浏览器窗口的大小时,div会出现滚动,但整个div的背景色却无法呈现。 It is rendered only for what portion I have seen when I resize the window. 它仅针对调整窗口大小时看到的部分进行渲染。
My styleclass 我的风格课
html,body{height:100%;}
.rightDiv{ height:100%;width: 39%;background: #3F5D91;float: right;color: #F0F0F0;}
Plz help me to get out of this problem. 请帮助我摆脱这个问题。
Thanks in advance. 提前致谢。
I've tested this using a local html file: 我已经使用本地html文件对此进行了测试:
<!DOCTYPE html>
<html>
<head>
<style>
html,body{height:100%;}
.rightDiv{height:100%;width: 39%;background: #3F5D91;float: right;color: #F0F0F0;}
</style>
</head>
<body>
<div class="rightDiv">Hello</div>
</body>
</html>
and on Firefox 18.0.2/Windows7 I see the div on the right, coloured blue, and I see a scroll bar when full-screen, or resized. 在Firefox 18.0.2 / Windows7上,我会在右侧看到div(蓝色),并且在全屏显示或调整大小时会看到滚动条。
Scrolling reveals the rest of the div with the background colour intact, so I can't account for why you see that. 滚动显示div的其余部分,而背景颜色保持不变,因此我无法解释您为什么看到它。
However, I'm wondering if you actually want to see the scroll bar. 但是,我想知道您是否真的想看到滚动条。 Setting an element to 100% usually means you just want it to fill the viewport, not spill over. 将元素设置为100%通常意味着您只希望它填充视口,而不是溢出。
If this is the case, then you need to remove any default margin that the browser applies to elements that contain your div, eg the body. 如果是这种情况,则需要删除浏览器应用于包含div的元素(例如主体)的任何默认边距。 Setting: 设置:
html,body{margin:0; height:100%;}
will make the div fit properly. 将使div合适。
Incidentally, sites like CodePen and JSFiddle offer the option of applying reset style sheets like Normalize and Reset , and you should watch out for these being pre-selected when you create a new pen/fiddle (JSFiddle does this for Normalize). 顺便说一句,诸如CodePen和JSFiddle之类的站点提供了应用诸如Normalize和Reset之类的重置样式表的选项,并且在创建新的笔/小提琴时(当JSFiddle为Normalize执行此操作时)您应注意这些被预先选择。
I had such problems. 我有这样的问题。 Only one thing helped me here. 这里只有一件事对我有帮助。 When I needed 100% height for body element I had to set him this styles: 当我需要100%的身高作为身体元素时,我必须为他设置以下样式:
body {
position: absolute;
top:0;
bottom:0;
left:0;
right:0;
-webkit-background-size: cover; /*makes background cover whole page
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
similar things you can involve to other elements. 其他元素可能涉及的类似事物。
