The most likely explanation is in the Web browser software you are using. Be sure to note the version of the software. Compare this to the software and version you are using on your computer. For example, if you use Netscape Navigator 2.0, try looking at the problem pages on a computer which uses Netscape Navigator 4.x. Different browsers interpret HTML differently, so what looks good on one browser might not look good on another.
Some Web pages display better on specific browsers.
If computers running the same version browser as yours display certain pages correctly but your browser doesn't, perhaps the cache entry on your hard drive for that page has been corrupted. These temporary files can be damaged without damaging your computer or hard drive. In Internet Explorer, from the Edit menu, select either Options or Preferences . Click the Advanced tab, then in the Cache section, click the Empty button. If Cache does not appear in the Category list, click the arrow next to Advanced .
