Hello,
The row height depends on the content height. Rows have the option to set full-screen height. Besides rows have the option to make columns of equal height.
You can add a class to a row or a column and set min-height by means of custom CSS.
As for the attributes:
Please navigate to Dashboard -> Products -> Attributes -> Color -> Configure items, enable swatch as shown http://prntscr.com/jskm29
Navigate to Theme Settings > Shop > Attribute swatches > choose pa_color (your color attribute). Enable “Use images from product variations” if you want images to be taken from the product variations.
Make sure each variation in a variable product has an image: http://prntscr.com/kk870w
Best Regards
