I have updated to the latest version of Dreamweaver cc (19) and there are error messages coming up on the bootstrap 4.3.1.css page.
Lots of the same errors 'expected RBRACE on lines …..', .
Also two other errors 'duplicate property 'text-decoration' found' and 'duplicate property 'position' found.
Is this anything to do with me updating to latest version or is it nothing to worry about?
The error messages occur because the validator does not recognise the advanced CSS features. Nothing to worry about.
Are these errors or warnings? Do you have an example of the page online?
The first message is an error message:
The second message is a warning:
