Does anyone know if there is a way to adjust the height of a module? I am working from one of the starter templates, and want to adjust the header module to a smaller height. I've tried getting in the code and changing it there, as well as adding in code for height, but still no luck. Is this possible, or am I going to need to start from scratch? It seemed to adjust the width without problem.
Yes, it is possible.
You should clone the starter template and create your own, then edit the code. But the height might be set in various places, because the template will support different email clients... So my guess is that you are forgetting one of these settings.
