Is it possible to slightly modify the layout of an existing website so it will more flexible and adjust to various viewing devices?

The visual display of many WordPress website elements can be changed to have a more flexible dimension. Usually the way this is done is by changing the fixed dimensions, measured in pixels, to variable dimensions, measured as a percentage of the total width of the website layout or in units called an em. But just changing everything to a percentage or ems does not immediately solve all issues. Other website design control can be done using the @media selector.

Depending on the complexity of an existing website design, the number of needed changes could add up to be resource and time consuming. This would be a good time to have a conversation with a website designer to compare the cost and value of  fixing the layout of an existing website to installing a new WordPress theme that has a more flexible layout already integrated. Consider if the existing website is using complex navigation menus, images in the background, large decorative elements, tables to control content, and heavy use of sidebar widgets.
