Tip straightening the page elements

If we add or change the size of the template column, Even in his interface as in the preview or the rendering of the various browsers look smooth without the slightest blemish, but in fact broken a Page Element, sidebar column appears sag downward, between the columns overlap and like truncated.
These short tips may be helpful, and I have to apply in any modification of the template on blogger.

We only add the code governing the Page Elements, held just above the tag ]]></ b: skin>:

body # layout # main-wrapper
(Width: 300px) ....... (adjust the width of main-wrapper)

or

Body # layout # sidebar-wrapper
(width: 200px) .............. (adjust the width of sidebar-wrapper)
