In order to make the website more accessible, and follow the guidelines provided on various government websites, I decided to:
Redesigned layout of the website with Bootstrap's Grid System, so that it could be 100% responsive. Now users can enjoy reading it from their laptop, tablet, or smartphone. The Ctrl + and Ctrl - keyboard shortcuts allow users to resize text up to 500%.
Fixed all contrast issues by changing hex value of navbar and link colors. Now every text on the website passes the AAA Level, which requires a contrast ratio of 7:1 for normal text and 4.5:1 for large text. (WAVE Accessibility Tool used to verify).
Corrected errors found with WAVE, regarding the <html> language used on the website. Fixed by including lang='en' in the tag.
Followed the usability.gov visual design basics while creating the website. Gave a clean and professional look, without sacrificing usability.
Made sure every link opens in the same page by removing the target='_blank' code. This has been done so that the back button of the browser will always work.
Made sure that every non-text element has a proper alt="" tag, in order for screen readers to not miss any feature.
