Add “blackify” and “enlargify” tools to your browser in 2 easy steps (12 steps if you use IE)
February 16th, 2007 at 05:51pm jabago
The internet has clearly become the most sensible medium for keeping up with the news, technology, and, well, everything. While some people are content to read small black text from a computer monitor all day long, most find that it makes their eyes sore. I’ve found that reading light colored text with a black background (like what you’re reading) greatly reduces the strain on my eyes. Unfortunately, most of the best sites on the web are formatted with black text on a white background. To fix this, I’ve created a couple buttons that will "blackify" and "enlargify" any website.
If you’re using Firefox, Safari, Opera, or Netscape (Internet Explorer users click here), simply drag each of these buttons up to your bookmarks toolbar. If you don’t like them, you can right click on them on your toolbar and select delete. They won’t harm, track, or spy on your computer.
Now browse to any website (or click here to go to wikipedia), then click them one at a time. Voila! The blackify button will render the page black with light text, and the enlargify button will enlarge all the text and convert it to an easy to read font.
If you want your blackify and enlargify buttons to include these icons 
, you will need to add them to your browser slightly differently. For instructions, click here for blackify and here for enlargify.
How do they work? These buttons each call a JavaScript function that imports a new cascading style sheet (CSS) from the jabago.com server. The blackify style sheet replaces all background images and colors with black, all text with light grey text, and all links with light orange. The enlargify style sheet increases all text to 24 pixels tall and replaces the all fonts with arial for easy reading. Feel free to download and modify the style sheets and scripts.
I’m also working on some custom blackify and enlarfify buttons that reformat some of my favorite web sites. You can find all of the web tools I create listed here.

Sweet!
Any chance of an OpenSearch plugin for ForeFox being written?

This is so awesome! Thank you very much for this very logical, eye-strain reducing vast improvement to my Internet world.
I am a security guard who surfs nearly all night (and alot of the day lol) from my vehicle. Soon, i will be working another internet based job while on duty, too.
In the past, I’ve had to dim the brightness and gamma on my graphics card, but now, I can just ‘blackify’ everything! wonderful! Make it always default so that I don’t have to hit that button for every page? Thanks!

superbe! I’m very grateful and very impressed. Now I’ve seen my own site ‘blackified’ I want to change it permanently. Uses less electricity too, I would imagine… or am I being silly here?

Its really nice to have Black google it helps in reducing eye strain . Make it default as soon as possible .

Too cool.
It would be an additional adv if the button’s functionality toggles on second click.
could you also make another change –The text in the required fields has become too light.

Thank you! I get really bad headaches from bright light and I am on my computer a lot. This will be so much better! Do you plan a Firefox extendtion in the future? It would be great to have the buttons on the main tool bar.
Thanks Again, your my Hero!

I’ve posted the Blackify style on userstyles.org. To apply the Blackify style to all web pages without having to click a button every time a new page loads, first you will need to install the “Stylish” Firefox extension located here: https://addons.mozilla.org/en-US/firefox/addon/2108. Then go here http://userstyles.org/style/show/2154 and click “Load into Stylish” button, and click “save.” Blackify will automatically be active for all web pages. To turn it off, click on the stylish icon in the bottom right of your browser, mouse over “global styles” and uncheck Blackify.
