<body> <h1>Alternative image classes in Markdown</h1>
<h3>The Problem</h3>
<p>My main problem with Markdown is that I'm unable to give classes to images. I like to have classes for everything. The benefits I have from giving classes to nearly every element is that I'm in full control when I design a website. If I'm using a lossy mix of direct selectors and classes it becomes messy.</p>
<p>However, let's assume I'm writing an article with a lot of images. I don't want them all to just "be" there, I want to style them. I want them to float to the left and right, have borders or apply shadows or whatever else. I want to use the full potential of CSS. </p>
<h3>Markup</h3>
<p>The markup for images in Markdown is pretty simple as you can see below:</p>
<pre><code>
</code></pre>
<p>You can apply an alt Text by writing it between <code>[</code> and <code>]</code>, an title Attribute can also be set by writing it in quotes right after the URL or PATH of the image. The only way I found to apply a specific style to images in Markdown is "hacking" into the <code>title</code> or <code>alt</code> Attribute. I decided to do it with the <code>title</code>, it would work the same way with alt.</p>
<h4>Markdown</h4>
<p><img src="http://cdn.eyeem.com/thumb/h/800/605f2220bc97deaa5c22e9bf427893c2cfcc458c-1377867949" alt="Image of a Car.">
First we define an image in Markdown. It's the same you can see above. <em>Notice: It is already styled by CSS (see line 23)</em></p>
<pre><code>
</code></pre>
<p>The next step is to apply a title Attribute to the image. </p>
<pre><code>
</code></pre>
<p>We'll now use this title Attribute to style specific images.</p>
<h4>CSS</h4>
<p>To use our "hacked" class we now need to use a special CSS Selector Method: The Attribute Selector. With the Attribute Selector you can easily access an Attribute, similar to styling an <code>h2</code> an Attribute Selector Style applies to all matching elements. In our case we'll likely want to address images only.
The markup is pretty easy:</p>
<pre><code>img[title*="imgClass--rounded"] { -webkit-border-radius:3px; -moz-border-radius:3px; border-radius:3px;
}
</code></pre>
<p>This small snippet simply points to "an image with a title attribute that contains imgClass--rounded". There are other selectors like that, e.g. <code>a[href$="https"]</code>,<code>input[type="text"]</code>,<code>div[class^="whatever"]</code> - I'll maybe cover them in a blog post.</p>
<p>To prevent conflicts I decided to name all "classes" I apply to the image <code>imgClass--</code> followed by the name. Below you can see some examples, hover them to get the Title attribute, the last word always represents the "class".</p>

<p>Another use-case could be to float an image to the right or left as shown below. </p>
