I would like to increase the size of Gmail text--not only the text in emails that I write, but the font size of all text in Gmail--the inbox emails that I see, as well as the text that I read when I open up an email. Gmail's settings allow me to increase the text of the emails that I send, but I want all text larger.
Is there a style that will let me do this? I found these instructions here: https://readingonscreen.wordpress.com/text-adjustments/gmail-text-size/
I installed the Stylish extension in Chrome (if someone has a solution for Chrome or Firefox, or both browsers, any way is fine with me); I copied and pasted that user style, but after logging into Gmail, the text was the same size as it was before. Not only that, but I clicked on teh Stylish icon, and evidently Stylish wasn't even seeing this as an operating style (there was some phrase that showed that it wasn't applying the style). I had saved the style; I went in and inserted https::/// blah blah in front of the URL, but that didn't change things.
Is there anything else I can do to apply this userstyle to Gmail? Or is there any other style I can apply, that will increase the font of all Gmail text?
