Layoutgrid vs. Flexgrid

[Erik88]

I made a website using WB14. A break point is set at 480.
I notice that a Photogallery placed in a Layoutgrid nicely reduces all content in size when less than 480 is available. It seems that a Photogallery with same width placed in a Flexgrid does not have that behavior. The size of the photos is not adequately reduced.

Are settings for Flexgrid available to get the same result as with the Layoutgrid?

Thank you.

A flex grid uses 'flexbox' so if you want the object to be flexible then you will need to set the flex box properties (flexgrid/shrink) otherwise the object will have a fixed size.

Note in that version 15, the flexgrid has an 'easy mode' where most of the flexbox properties will be set automatically.
