Special character must be escaped but I can't find the error

[etcare]

I'm not really sure why I'm getting this error on dreamweaver. Everything seems to be running fine but I keep gettting this error. Anyone know why?

It's most likely to be that the Dreamweaver validator doesn't understand - data-group="["pruning"]

If its only that which evokes a validation error then forget it and move on.

Test by removing them

These are illegal characters for the data- attribute (outside of the quotation marks)

I don't know what 'data-group [ ]' is myself but the [ ] are not illegal after investigation, Jon is most likely onto something with the double/single quote aspect.

EDITED:

Maybe the brackets ARE illegal (persoanlly I've never come across them before myself) I was getting some feedback from an old post on Google where it looks like someone else is using them for some reason, or trying to use them:

https://stackoverflow.com/questions/34154181/jquery-expression-for-data-group

But I cant find any reference anywhere else much.

[BenPleysier]

The syntax for the data- attribute is

data-name="data value"

Where name cannot be in capitals and datavalue can be any string. The use of brackets within the datavalue can be associated with a framework.

'Associated with a framework' well there you go, does nothing work these days without one of them being involved????? Everything one seems to view these days requires some kind of 'extra' package, mostly package's' just to do the basics.

 I was just exploring something the other day and before I could get passed 'ground zero' I needed to install 'Brew' and then after that 'Composer' then after that I need this package and that package, its a ****** joke!

DW's validator wants you to write the following...

data-groups=["pruning"]

...as something along the lines of...

data-groups="['pruning']"

...with alternating double and single quote pairs.
