June 16th, 2022 by zoltan · No Comments

Two fists with the words 'good' and 'evil' tattooed on the fingers.  The owner of the fists is wearing an Internet Explorer shirt and has his face out of camera to protect his identity.

IE is dead. It should have died a long time ago (didn’t it die already). But I have nostalgia for that nightmarish piece of software because, ironically, it made people care about web standards. Think I’m wrong? Read on.

July 19th, 2020 by zoltan · No Comments

In the past, I have been an accessibility lead on a project that had videos with scenes that could potentially cause seizures. When I approached the video creators about these issues, they said they didn’t know how to fix these issues.

This article shows that it’s not too hard and you can fix these problems in no time.

Using PEAT To Create Seizureless Web Animations

April 2nd, 2017 by zoltan · No Comments

Photosensitive Epilepsy should be a concern to anyone creating any type of animated media. As a matter of fact, in order to pass WCAG Level A, a web page cannot “contain anything that flashes more than three times in any one second period, or the flash is below the general flash and red flash thresholds”. Testing this requirement may seem a little daunting at first, but luckily there is a free tool called PEAT that web developers can use to test if their animations and videos can cause an epileptic attack. This blog post talks about how to use PEAT, what it’s limitations are, and how to work around them.

Accessible Form Placeholder Text

February 20th, 2017 by zoltan · 3 Comments

Placeholder text is used quite a bit in modern HTML5 forms. It is not meant to replace form labels, but is intended to be a hint about the format of what the form field data should take. While checking the accessibility issues on a recent project, I noticed that placeholder text is sometimes indistinguishable with form field values when using certain screen reader/browser combinations. This post talks about how to work around this issue with just a little bit of JavaScript.

Creating Alpha Channel JPEGs Using SVG

November 7th, 2015 by zoltan · 2 Comments

sun-alpha-thumb PNGs with alpha channels are great, but they can take up a lot of bandwidth. Alternative image formats such as JPEG-XR, JPEG 2000 and WEBP are more efficient, but they are not supported by FIrefox (and may never be). In comes a full cross-browser solution: SVG files that encapulate a JPEG with an alpha channel. This post will cover how to create these image files a number of different ways, and show how you can animate these images as well.
