I am designing a website using CMSMS and have finished the initial layout and template part. I have a global content block image header that appears across all the pages in the website. The image header looks fine and fits the window perfectly when the windows is in maximized position. When I minimized the window or changed the window size, the image header looks distorted and appears in two lines instead of one line. Moreover, in the main content section, the side table (which appears properly in the window normal position) appears at the bottom of the page when I minimize or change the size of the window.

Any pointers on how to handle the same objects for different sizes of the browser window?
Thanks in advance,
Neo
