Hi shepcntr,
thanks for using MH Elegance lite.
In case CSS changes don’t take effect after you’ve saved them properly, it’s possible that your site is cached somehow. That means you could check if you’re running any caching plugins and clear the cache including your browser cache.
You also might want to make use of tools such as Firebug or your browsers inspection tool to inspect your changes and see if your modifications possibly are conflicting with other CSS on your site.
In addition please keep in mind that you shouldn’t modify code within the original theme files as these changes will be lost after theme updates. Instead you should make use of a child theme to modify your theme.
