Ever since I've started reading up about blogging, I've learned that the most important thing when it comes to designing a new theme or tweaking an existing theme is that the end product should be accessible by all.
And by ALL, I mean ALL. Including people with disabilities. Including people who are are visually-impaired (yes, they read blogs too).
(1) Always insert a description to your image tags so that blind readers can still read your images:
Code:
alt="Description of your image"
And always define the definition of your links:
Code:
title="Your link description here"
(2) Your links in your blog post should be somewhat indicated. Visually-impaired bloggers cannot tell the a red link from a chunk of black text. So if you don't indicate that the red words are actually links, they won't see it. Also, do not bold your words unnecessarily because some people automatically assume that bold words are links. However, links on your sidebar do not NEED to be indicated because bloggers are usually aware that the stuff we have on our sidebars are, more often than not, links.
So how accessible is your blog? What are the modifications that you have done/taken into consideration when designing a theme?
