Performance problem with CSS rule

Post by rmarchand » Mon Sep 07, 2020 12:55 pm

We occur a performance problem with a CSS rule on our framework that contains an action (template insertion with ID numbering).

When the CSS includes rules with an ID selector
for exemple:

Code: Select all

--> the action take a long time (25 seconds).

If we delete the ID selector
for exemple

Code: Select all

--> the action is practically immediate.

Are you aware of this problem or an idea where the problem comes?

Thank you

The CSS attribute selectors should be very fast. So we do not know of such a problem.
If you can put together a small project XML + CSS + steps to reproduce the problem, please send them to "" and we can look into it further. Please also include information about the version of Oxygen you are using.
