I did a fresh install of WP, GP to rebuild our website. I have been using GP for many years and like the theme and plugins.
I have been using the sections option in the previous site to design and want stay a much as close to the defaults.
It was sometime difficult to construct and the column plugins you recommend seem not to be compatible.
That is why i started with default gutenberg design.
1) Below the header i created two columns for text and three columns for pictures with text.
The right alignment is 0 in all cases and as soon as the mobile menu drops in there is no margin left and right.
please note i am still configuring the options in the customisation area of GP but will hold horses until you help me to solve this small problem.
2) Can you advise me the best multi language (selector) plugin (free if possible that you recommend)
