如何确保均匀显示 DIV 内的背景图像 [英] How to ensure the background image inside a DIV is evenly shown

问题描述

我的 ASP.net 页面中有以下代码(我希望它具有响应性):

<div style="width: 100%; height: auto; min-height: 50px; max-height: 50px; background: #00ff00; background: url('/theImages/mobileMWBtn.png'); background-size:封面；文本对齐:居中；">请登录

CSS:

.mobileTabsNav{显示:无；宽度:100%；溢出:隐藏；}@media(最大宽度:715px){.mobileTabsNav{显示:块；}}

图像的底部似乎被剪掉了:

当我将其更改为 background-size: 100% 100%; 时，图像在某些屏幕上被拉伸太多，如下所示:

如您所见，图像失真.

无论如何要确保不同屏幕尺寸的曲线完全相同，还是我必须添加三个单独的图像?

小提琴上使用的图像:

.mobileTabsNav{宽度:100%；溢出:隐藏；}

<div style="float: left; background: url('http://i.stack.imgur.com/NnCbY.png') no-repeat; min-height: 50px; min-width: 10px; max-宽度:10px；背景尺寸:包含；">
<div style="background: url('http://i.stack.imgur.com/KbPm8.png')"></div><div style="float: right; background: url('http://i.stack.imgur.com/rll1d.png') no-repeat; min-height: 50px; min-width: 10px; max-宽度:10px；背景尺寸:包含；">

解决方案

我要做的是创建一个背景图像，它可以很好地用作重复图案(平铺)，然后使用 border-radius属性以获得圆角.

在这种方法中，无论屏幕大小如何，点的大小始终相同，并且您只需要为所有设备提供一张图片.

.mobileTabsNav {}.mobileTabsNav .inner {最小高度:400px；背景:#00ff00 url(http://i.stack.imgur.com/M8WDz.png);文本对齐:居中；边框半径:25px；}

<div class="inner">请登录

顺便说一句，这里是如何裁剪背景以使平铺看起来正确:

I have the following code in my ASP.net page (I would like it to be responsive):

<div class="mobileTabsNav">
    <div style="width: 100%; height: auto; min-height: 50px; max-height: 50px; background: #00ff00; background: url('/theImages/mobileMWBtn.png'); background-size: cover; text-align: center;">
        PLEASE SIGN IN
    </div>
</div>

CSS:

.mobileTabsNav
{
    display: none;
    width: 100%;
    overflow: hidden;
}
@media (max-width: 715px)
{
    .mobileTabsNav
    {
        display: block;
    }
}

It seems the bottom portion of the image is getting cut off:

When I change it to background-size: 100% 100%;, the image is stretched too much on certain screen as in the example shown here:

As you can see the image is distorted.

Is there anyway to ensure the curve is the same across the board of different screen sizes or do I have to add three separate images?

The image being used on the Fiddle:

.mobileTabsNav
{
    width: 100%;
    overflow: hidden;
}

<div class="mobileTabsNav">
                        <div style="float: left; background: url('http://i.stack.imgur.com/NnCbY.png') no-repeat; min-height: 50px; min-width: 10px; max-width: 10px; background-size: contain;">

                        </div>
    <div style="background: url('http://i.stack.imgur.com/KbPm8.png')"></div>
                        <div style="float: right; background: url('http://i.stack.imgur.com/rll1d.png') no-repeat; min-height: 50px; min-width: 10px; max-width: 10px; background-size: contain;">

                        </div>
                    </div>

解决方案

What I would do is create a background image that works well as a repeated pattern (tileable) and then use the border-radius property to get the rounded corners.

In this method, the dots will always be the same size regardless of the screen size, and you only need a single image for all devices.

.mobileTabsNav {
}
.mobileTabsNav .inner {
  min-height: 400px; 
  background: #00ff00 url(http://i.stack.imgur.com/M8WDz.png); 
  text-align: center;
  border-radius: 25px;
}

<div class="mobileTabsNav">
    <div class="inner">
        PLEASE SIGN IN
    </div>
</div>

As an aside, here is how the background might be cropped to get the tiling to look right:
