Hello Mihai
Go to dashboard > appearance > customize > additional css
paste the given code below in the additional css tab
main#innerpage-box div#content-box .galleryinnerbox img {
max-height: 150px;
}
change the max height element value if you want to decrease or increase the height of the images in the gallery.
then click on publish to save the changes.
Thank you for contacting us
Thank you for the answer! If there are any others who want 4:3 aspect ratio max-height: 218px works better than 150px.
Working at Gallery I discovered an issue. When a gallery item is opened on mobile, the image larger than the screen. On a computer screen it looks ok. Can it be fixed for mobile screens?
