What can be done with web sites that the writing is hidden by black areas. If you hold down your mouse button and drag it , it will lighten up the area so you can read it.
Thanks for any help
Do you experience a lot of them or only one here or there. If it is only here or there then most likely it's poor website design. If there are a lot then it's most likely some setting in your browser. Post a link and I'll try it on my computer.
Make sure you have the latest drivers for your video card. If you have a Dell, HP etc go to the manufacturers website and punch in your computers info and see if there is a newer version available. This program ( freebie ) has a scan of basic drivers built in, it's in the Toolbox section. http://www.iobit.com/advancedsystemcareper.html
Can't remember if it want's to install a Toolbar, if so decline, in fact decline anything except the main program.
I had a similar problem in the past and I remember it had to do with an odd setting in my browser at that time ( was using Mozilla back then), then I tried to open the website with another browser (Chrome) and it was fine, with Opera was also OK, so the problem was from the browser. I think you did not mention opening the problematic sites with different browsers to see if there will be a difference. Hope you will resolve the issue soon.
