|

<p>I've been playing with an exciting feature of HTML5 that I hadn't heard of: the <code class="language-html">contentEditable</code> attribute. It's magical! It just makes anything suddenly be editable in-browser! It also finally provides me with the thing I've been wanting ever since growing dissatisfied with text editors: A way to build a <em>new</em> text editor, <em>without</em> having to actually code up the guts of text movement, manipulation, and entry. Oh, happy day!</p>
|
||||
<p>More on this as the situation progresses.</p>
