While using web site templates a person needs to be careful about certain things. It would not be a good idea to opt for the wrong theme design. This will give one‘s site a dated look which is definitely not desirable. One should also ensure that a template is in sync with the theme and content of a site. For instance, a children site should not use a corporate theme based template. This looks quite unprofessional and mars the appeal of the site.
CMS helps to separate design of web site from its content. It means designer develops a web site and gives it to its owner or manager who can fill a certain design with different content. If necessary the content of web site, its images and graphics can be easily edited without intervention into design of web site. All changes become visible as soon as you make them. (Don‘t forget to reload page after making changes). Even if you are not an expert of HTML coding, you can easily manage the content of your web site yourself.
