FontFlex – Read better, browse better.
This plugin is specifically designed for people who find it difficult to read small text on websites. Some web designers wanted their websites to look classy and modern using thin fonts that are also very small. This defeats the purpose of making these websites easily legible for many matured audiences who may have multi eyesight problems. They compromised on look and feel rather than practicality. This can lead to a very tiring and frustrating experience. This is where this plugin shines as it allows us the readers to tweak the fonts and font size for each website to suit the needs for people with presbyopia and other eye problems that just need a more legible font size to consume the contents of any website. The settings can be customised per website so as it does not require fiddling with zooming in or making the system fonts bigger which also does not translate to how the fonts look like on all websites. Thank you for this wonderful plugin that will help those of us with reading bigger fonts without making the websites look too different like how it’s supposed to look like. Highly recommended and I’m really happy for the ability to read comfortably on any given website.
