Html Template in dreamweaver

It sounds to me like your old site might have been a single page site, where multiple pages were all together in one file, hidden or revealed as you clicked through a menu system.

It would have looked like you could scroll through your entire site in DW's Design View, because Design View ignores most CSS and javascript. But now it sounds like you're using a more typical multi-page site instead. If you properly defined a site originally, your other pages will be located under Window > Files.

If that's the case, each will need to be opened individually, there' s never been a function in DW to allow you to simply scroll through each individual page of a site to make modifications. 

To work with Dreameaver Templates (DWT files), switch from LIVE to DESIGN View (Ctrl/Cmd + Shift + F11).

Or use the drop-down from your Document Toolbar (see screenshot).

When documents don't behave as expected, it's time to validate your code and fix reported errors.

Dreamweaver CC is much less forgiving of code errors than legacy CS6. 

Go to Window > Results > Validation.  Check document.

Hope that helps.

It's possible in the old version of DW you had not been using live view, but were instead using design view which can be very inaccurate in its display and cannot be used with dynamic content.

With that said, the only thing DW related in your pages is an old swap image script. And I am not seeing bootstrap either. Maybe you had taken some influence from its base code, but the css is definitely custom.

Either, you are telling us porkies or you have shown the wrong website.

• The site is not a Bootstrap site
• The site does not contain any Dreamweaver Template

I will leave it to others to determine if this is a spam post.
