Preview in Browser
As you edit your pages in Design view, you may notice some elements will appear out of alignment from time to time. While it can be distracting, it is easy to fix. Simply save your page (Control + S) and refresh (F5). This will realign the page.At times, however, you may still notice some minor differences in how your page looks in Design view and how it looks when you click on the Preview tab.
To get the most accurate look at how your pages will appear once they are published to your web host, you should go to File > Preview in Browser.
You can select various browsers (any you have installed) and view at a variety of different screen resolutions. At the least, have the current version of FireFox installed. You can do a search on Google for these browsers. We test our templates in numerous browsers to make sure that everything shows just as we want it to!
NOTE: You should test each and every page often by going to File > Preview in Browser!
