Why doesn't Live View always update when I make an edit to CSS?

[Mr. Positronic]

Using Dreamweaver CC 21.0 on a Mac 10.15.7

I've noticed that when I change a parameter in CSS such as font size, the Live View in split mode will not always update automatically to reflect the change.  I have to toggle the code view from CSS to HTML to force it to redraw the Live View.  It has gotten worse, the more complex the document.  Is this a familiar bug or should I look for something that may be causing a conflict?

Ctrl + S  = SAVE.  Do this often on all documents during editing sessions.

F5  = REFRESH.  This is necessary for Live View to redraw changes on your screen.

Alternately, switch to Design View which is quicker for editing but less accurate at rendering advanced CSS.

Document Toolbar > Design View

Thanks, Nancy.  F5 is what I was looking for.  And you're telling me that forcing a refresh is normal, not because I've written some bad code.  Interesting how when I first started working on this page, it seemed to refresh on its own.

And I hear you about saving.  SAVE SAVE SAVE.  Although my default keyboard shortcut for save is CMD + S.  I don't see a shortcut for Save All, so I might make one ...

"Interesting how when I first started working on this page, it seemed to refresh on its own."

You must have been in Design view, not Live view.

"my default keyboard shortcut for save is CMD + S"

Because you're on a Mac. On PCs, Ctrl is the Cmd equivalent.

You can disregard Paul-M's remarks.  He obviously misread your question which has nothing to do with Real-Time Preview.

The live preview feature in Dreamweaver is temperamental,  you could go into pereferences => real-time preview and change the setting to 'default to static browser preview' then just manually refresh your browser. I've found livereload with the browser extension works better ...
