[英]Dynamic Sticky Footer Height with Ryan Fait's Code
Ok there are a fair number of questions about Ryan Fait's sticky footer , BUT please don't disregard this question immediately! 好的,关于Ryan Fait的页脚有很多疑问,但是请不要立即忽略这个问题! What I am trying to do is have a dynamically sized height for my footer and have it stick to the bottom of the page.
我想做的是为页脚设置一个动态大小的高度,并将其固定在页面底部。
Ryan Fait's solution is to wrap all the page content in #wrapper
and set #wrapper
's margin-bottom
to the height of the footer. Ryan Fait的解决方案是将所有页面内容包装在
#wrapper
,并将#wrapper
的margin-bottom
设置为页脚的高度。 This works very well when hardcoded into the CSS, but I don't know how large my footer is going to be. 当将其硬编码到CSS中时,此方法效果很好,但是我不知道页脚有多大。 Because of this, I want to be able to set
#wrapper
's margin-bottom
with javascript. 因此,我希望能够使用javascript设置
#wrapper
的margin-bottom
。 So far, I have been unsuccessful. 到目前为止,我一直没有成功。 Here is my setup.
这是我的设置。
I have been at this so long, I have very little hair to pull out. 我已经呆了这么久了,我的头发很少拉出来。 Do you see where my mistake is?
你看到我的错误在哪里吗?
The Code on JSFiddle JSFiddle上的代码
HTML 的HTML
<body>
<div id="wrapper">
Wrapper
</div> <!-- #wrapper -->
<footer>
Footer
</footer>
</body>
CSS 的CSS
* {
margin: 0;
}
html, body {
height: 100%;
}
#wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto; /* Negative margin set with JS */
}
footer {
height: 100px;
}
JQuery jQuery查询
$(window).load(function() {
set_window_bottom_margin();
});
function set_window_bottom_margin() {
var margin = $('footer').outerHeight(true);
$('.wrapper').css('margin-bottom', margin * -1 + 'px');
}
you could do this in css nowdays: 您现在可以在CSS中执行此操作:
html, body {
height:100%;
width:100%;
margin:0;
}
body {
display:table;
}
main, footer {
display:table-row;
}
main {height:100%;background:red;}
footer {background:green;}
footer:hover br {display:none;}/* whatever else on footer:hover s for demo purpose */
<main>
<div>
main
</div>
</main>
<footer>
<div>
footer<br/>
footer<br/>
</div>
</footer>
