What I was after was a plugin that would let me put columns into wordpress blogs. I didn’t want to be tied to a particular theme. I just wanted a plugin that would work with any theme at all. I also wanted the columns to collapse down into one column for mobile sizes.
My previous solution was to use Justin Tadlock’s Grid Columns plugin. This is a great columns plugin in almost every way. The one downside was it didn’t collapse down to single column at smaller widths. To solve this I went into his plugin’s CSS and wrapped the whole lot in a media query.
It worked like a charm.
I knew that this probably wasn’t the way to go after Justin updated the plugin and I realised I would have to go and re-edit the code again. Also I received some excellent constructive criticism in the comments!
The settings are in the Plugins dropdown in your wp-admin.
The width that the Collapse plugin kicks in is at 650px but you can change that in the plugin settings. Hope it helps!
