You could use a content management system (CMS) which is usually used so that the website designer doesn't have to do mundane daily updates; they can be done by unskilled people online without accessing the original code.

Most CMS software include WYSIWYG editing tools allowing non-technical individuals to create and edit content.
Google "content management system" for lots of free code. These are two that I've seen mentioned in other posts but I've never used them.
