When searching the net it surprises me how poor the print on some sites are.The wording is so faint it can hardly be seen plus the choice of colour ie yellow lettering on white background..Is it possible to darken these ads. on a page by page basis rather than change the default??????/ Thanks!!
Start by checking how your monitor is set up. If you can't clearly see both '0' and '10', on the numbered lines here, it's not properly configured:
