resizing is generally harder than not.  If you don't want it to resize, you can just set the width in pixels rather than percentages.

connectipedia.org has a fixed-width site.

fwiw, resizing is very useful in contexts where people can make use of more real estate.

i am comparing to wikipedia, where the sidebar is fixed, but the main part is flexible. how can i implement it here?

Set the width of the sidebar in pixels in CSS. Eg. width: 200px
