For users of screen readers, depending on the screen resolution, the two checkboxes are for opening and closing the side menus that appear to the left and right of the screen. This is designed both for large screens and for mobile devices with a touch screen. Checking either the main menu or sidebar checkboxes causes the menu to open from the left or right side of the screen, respectively. Clearing the checkox in either the main menu or sidebar closes the menu. The checkboxes are visible to screen readers such as JAWS and NVDA for Windows, Voiceover for Mac, and Orca screen reader for Linux. When a screen reader says "clickable" for both main menu and sidebar, that is for the respective checkboxes. End of explaination.

Dynamically-Resizing Televisions and Monitors

Let me ask you a question. Do you find yourself wanting a larger TV because a movie looks too small? Do you not like black bars above and below the movie that is formatted for ultra-wide screens? Before reading any further, I want to link to an article that talks about aspect ratios. Now, please note that this article will require anyone to have eyesight, so this will not be suitable for those who are using a screen reader. Of course, it might be helpful if anyone who is blind could visualize in their head. Maybe a Braille measuring tape could help?

Put it simply, a TV has an aspect ratio of 16 to 9, which is referred to 16:9 or 16×9. Most movies today are formatted to 2.35 to 1, or 2.35:1. An aspect ratio of 2.35:1 is for movies and 21:9 aspect ratio can be found in gaming monitors, but according to displaywars.com, it’s not the same size. Let me list the dimensions of the two aspect ratios given the size of 100 inches in diagonal.

Size Ratio Width Height
100 2.35:1 92.02 39.16
100 21:9 91.91 39.39

So the 2.35:1 format is slightly taller, but the 21:9 aspect ratio is slightly wider. I did some research regarding movies and gaming monitors and I saw that 2.35:1 movies can actually fit in nicely with a 21:9 gaming monitor. It’s in the “Movie Watching” section of the article.

So why do I want to talk about aspect ratios and why should screens dynamically resize based on content’s aspect ratio? If you have a desktop computer with a 32-inch monitor, do you ever watch movies? I do. Let’s consider the size of the movie in relation to the actual screen size. With a 32-inch monitor that I am currently using, the height of the 2.35:1 movie is less than 12 inches. To me, that is very small. If I forget about the information from the left and right sides of the screen in a 2.35:1 format, the result will be about 24 inches in diagonal when cropped to a 16:9 aspect ratio. (more…)
