Hi, I’m still experiencing problems getting my ‘mosaic’ tiled jetpack galleries to fill the available column width. see https://www.thediychronicles.co.uk
I tried the solutions already mentioned but;
if ( ! isset( $content_width ) )
$content_width = 640;
was already present in functions.php and adding the recommended css has had no impact.
This is driving me mad so any help would be massively welcome.
Cheers
Chris
