When changes have been made to locked regions in a template, you have the option of updating these regions in all template-based web pages.
This option is useful for making changes to a page header or any element that appears identically on every page.
Not sure if you’re still monitoring this for questions, but just in case…
My site uses a template which holds a banner image at the top and a Table Of Contents down the left side of every page.
Dreamweaver is fine to use, it just depends on how you use it, I personally use it but I still hand-roll my code so I don't run into any issues with it making a mess of my code. I don't think I've used them since high school, but you need to (do something like) set up a "new site" in Dreamweaver that points to the copied folder. If that does not recognise that the page you updated has children it will likely be an issue because of the path of the files.
Here is what you need to understand to get started with templates.
I'm currently in the process of redesigning a website, and I'm using Dreamweaver templates and libraries to maintain a consistent look on each page.
I've gotten to the point where I'm almost finished with the site, and wanting feedback from other people.
You will also learn how to use Dreamweaver CS5's template system to create new pages based on the custom design and layout that you've been working on in the previous chapters as well as to automate the updating of all the pages of your site when you make a design change.
Finally, you will also learn how to get Dreamweaver to automatically figure out which pages of your site to upload without your having to manually open and upload every one of them.
