changing font on 2010 for Site title

firebug points to line 345 in style.css

#site-title a {
    color: #000000;
    font-weight: bold;
    text-decoration: none;
}

Ok I have put font-family: sans-serif;
after text-decoration: none and even took out text-decoration: none but still can not get it to change.

Force refresh your browser (Ctrl + F5), or clear your browser cache.

That is the correct place, you can verify changes to the site title by replacing font-family: sans-serif; with something like font-family:"Times New Roman",Georgia,Serif or changing the color or font-weight. Make sure to refresh the page and you should see the change.

Be sure not to update your theme until you’ve transferred changes to the theme’s files onto a Child Theme or at least a Custom CSS plugin, to avoid loss of work.

thank you very much it was the clear your browser cache.
