How to display and disable all grid instructions in CSS script?

[pstein]

Assume I have web page which uses a CSS script with lots of rules.

Some of them have properties like

.foobar {
display: grid;
grid-template-columns: 1fr 300px;
grid-column-gap: 70px;
}

I want to get rid of all these grid-related instructions in all CSS rules.

How can I disable all grid layout stuff completely for all CSS rules of the current webpage?

I have no access to the original web server (and the original CSS) but want to overwrite the CSS script in my browser after loading.

Change display property, it only works if display: grid is used.
