My home page has a lot of columns - the less important ones are usually beyond the right edge of the page in a small screen. In Safari and Firefox that creates an unpleasant page "jump" or shift to the left when the page first loads. Instead of seeing the navbar and main articles, the page shifts so the content on the far right is within the page.

I found a cure for this behavior here: Getting Rid of the Page Shift

Adding this to the style sheet fixed it:

/*this is to keep page from shifting to left on load in safari and firefox*/

html { min-height: 100%; margin-bottom: 1px; }

html { overflow: -moz-scrollbars-vertical !important; }
