A Note About Website Navigation

Skip to main menu.

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 side 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.

About Grayson Peddie

Hello! I am a web developer and I have a passion for the world of Information Technology. I currently hold 4 CompTIA certificates (A+, Network+, Security+, and CySA+) including Cisco's CCNA (Cisco Certified Network Associate) certificate. Speaking of web development, I am a web accessibility enthusiast. I make sure that users of screen readers and keyboard users who cannot use a mouse can be able to access my website with just only the keyboard. Plus, I have learned a whole lot about Web Content Accessibility Guidelines.

So what are my hobbies? Aside from web development, I watch Star Trek: The Next Generation from time to time during the nights. I listen to music from the likes of David Arkenstone, Yanni, Checkfield, Cucso, Looreena McKennitt, Clannad, 2002, Enya, and even soundtrack from EPCOT Center (1982-1994), Tomorrowland, WALL-E, and TRON: Legacy. Oh, yes! Tomorrowland, TRON: Legacy, and WALL-E are the three movies I watch during Friday nights and every Friday night is my pizza night. I'm an optimist who likes to see what kind of future the world would look like. That's why I follow The Venus Project on Twitter (here's the website to The Venus Project. I do have a lot to cover in my introductory article in my website, so if you want to go in-depth and know more about me, that is the article to visit.
