[SOLVED] Have image fit 100% width on mobile platforms

Have image fit 100% width on mobile platforms

so I am currently implementing a mobile version to my website and everything is fine except I want to be able make it so the image will fill 100% width of the screen whether the user tuns it horizontally or vertically. The image fits 100% like normal on any non-based mobile platform, but does not on a mobile device. Any suggestions?

I currently am using

.blog{
    padding:10px;
    border-bottom:2px solid #eeeeee;
    padding:10px;
    background:#ececec;
}
.blog-img{
    text-align:left;
    width:100%;
    margin:0 auto;
    padding:10px 0 5px 0;
}

I've also tried:

min-width:100%;

Solution

The image fits 100% like normal on any non-based mobile platform, but does not on a mobile device.

It is not working as expected because you are giving the parent element .blog-img a width of 100%.

You need to directly target the nested img descendant element and give it a width of 100%:

.blog-img img {
  height: auto;
  width: 100%;
}

Depending on what you're trying to achieve, setting a min-width of 100% may be better in certain cases.

.blog-img img {
  height: auto;
  min-width: 100%;
}

Using width: 100% will stretch the img element to a width of 100%.
Using max-width: 100% will increase the width of the img element to the maximum total width of the img resource. In other words, this will prevent the img element from being stretched larger than it actually is.

Here is an minimal example highlighting the difference:

<p>Using <code>max-width: 100%</code></p>
<img style="max-width: 100%;" src="http://placehold.it/50" />


<p>Using <code>width: 100%</code></p>
<img style="width: 100%;" src="http://placehold.it/50" />

Since you're optimizing your site for mobile browsers, be sure to set a viewport meta tag:

<meta name="viewport" content="width=device-width, initial-scale=1">
