THANK YOU 'FACTOR 30' I LOOKED AT THAT AND I SEEM TO BE ACTIVE WITH 'AVATAR' BUT I STILL DON'T KNOW. WHAT 'AVATAR' AND 'GRAVATAR' ARE.
ALSO HOW DO I CHANGE THE ICON ABOVE MY USERNAME?
Yes the browser does cover the full screen width.
i clicked 'reset' in 'view/zoom' and got the original screen back! I tried 'control +' again and whilst the letter size increases the whole paragraph moves to the right again!
Thank you for trying to help me everyone!
if you have a mouse, hold the Control key down and spin the wheel on the mouse: one way makes the type smaller, the other way makes it bigger. You can stop when it's big enough to read.
