停用div上的缩放,但允许在网页上缩放(替代div) [英] Disable zoom on a div, but allow zoom on the page (an alternate div)
问题描述
有没有办法禁用缩放div或网站上的任何特定元素?例如,如果我想让页面可缩放,但不是#Header div,是否有一种方法使一个可缩放,而另一个不可缩放?
基本上,当您在移动设备上放大时,它也会缩放标题,但我希望标题始终处于固定大小(不可缩放)。
您可以使用此代码禁用整体缩放:
< meta content ='width = device-width;初始尺度= 1.0; maximum-scale = 1.0; user-scalable = 0;'name ='viewport'/>
但是,您可以使用条件CSS修复移动设备上的缩放问题:
下面是一个示例代码:
header {
position:fixed;
...
}
@media only screen and(max-width:720px){
header {position:absolute; }
}
此代码启用 position:absolute
当显示宽度小于或等于720px,并且标题成为页面的一部分,而不是固定在上面。
简单, 。
Is there a way to disable zoom on a div, or any particular elements on a website? For example, if I wanted the page to be zoomable, but not the #Header div, is there a way to make one zoomable, and the other not zoomable?
Basically, when you zoom on a mobile device, it zooms the Header too, but I want the header to be a fixed size at all times (not zoomable).
I know that you can use this code to disable zooming overall:
<meta content='width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;' name='viewport' />
In short: You can't do that.
However, you can use conditional CSS to fix zoom issues on mobile devices:
Here is an example code:
header {
position: fixed;
...
}
@media only screen and (max-width: 720px) {
header { position: absolute; }
}
This code enables position: absolute
when display width is less or equal 720px, and header becomes the part of the page, rather than being fixed on top.
Simple, and does the job.
