How to set height and change css overflow

I would ideally like to increase the height of the that have the attribute "data-hook=“restaurants.menu.item-view.description”. looking at the css the overflow is hidden and the height is only 40px so I would like height of at least 100px or a way to turn the overflow off.

I have added this custom code to the page and it works when I open the page in a new window or refresh manually. But it does not run when I navigate to the online orders in the same window is there any way to get the whole page to refresh when opening a page from the menu or a link?

Finally sorted if you set to all pages and set “Load code on each page” it magically starts working enjoy.
