Tabs Gallery moves around

I need the gallery in my Portfolio section to stop moving around when you press on one of the buttons.

Here a link to my site

Here is my public share link: LINK
(how to access public share link)

Your entire tab element is vertically centered, and its height is often defined by the height of the tab content element. So everytime you open a tab that has content that’s taller than the menu, then it recenters itself.

Give a minimum height to the tab content element, of the height of the taller content.

Thank you so much works great.
