使用 CSS 的响应式图像 [英] Responsive Images with CSS
问题描述
我发现调整图像大小以使其具有响应性很棘手.
我正在开发一个 php 应用程序来自动将网站转换为响应式版本.我有点被图片困住了.
我已经成功地为网站上的每张图片添加了一个包装类,并且可以很好地调整图片的大小.
我的问题在于自然小于窗口的图像,例如徽标和图标.我不想调整这些大小.
我的代码目前正在转换:
进入:
<img src="[src]"/>
我使用以下 CSS 的地方:
.erb-image-wrapper{最大宽度:90%;高度:自动;位置:相对;显示:块;保证金:0 自动;}.erb 图像包装器 img{宽度:100%!重要;高度:100%!重要;显示:块;}
这会调整所有图像的大小,但我只希望它调整超过页面宽度的图像的大小.我可以通过 CSS 实现这一点吗?
.erb-image-wrapper img{最大宽度:100%!重要;高度:自动;显示:块;}
为我工作.
感谢 MrMisterMan 的帮助.
I'm finding it tricky to resize images to make them responsive.
I'm developing a php application to automatically convert a website to a responsive version. I'm a little stuck on the images.
I've successfully added a wrapper class to every image on a website and can re-size the images quite well.
My issue lies with images that are naturally smaller than the the window, such as logos and icons. I don't want to resize these.
My code currently converts:
<img src="[src]" />
into:
<div class="erb-image-wrapper">
<img src="[src]" />
</div>
Where I use the following CSS:
.erb-image-wrapper{
max-width:90%;
height:auto;
position: relative;
display:block;
margin:0 auto;
}
.erb-image-wrapper img{
width:100% !important;
height:100% !important;
display:block;
}
This resizes all images, but I only want it to resize images that are over the width of the page. Is the a way I can achieve this via CSS?
.erb-image-wrapper img{
max-width:100% !important;
height:auto;
display:block;
}
Worked for me.
