Hi guys -- apologies if this was already answered, I searched quite a bit to do some due diligence but haven't found a similar question, so here it goes.
We have found the Marketo landing page builder to be very clunky/not user-friendly for building sophisticated landing pages and because of this, I would like the flexibility to purchase custom landing page templates via something like
Themeforest's Marketing Landing Pages and import them, then tweak whatever html/css as necessary. I haven't found any documentation to tell me the proper way to do this, and having a few difficulties with calling an external css sheet--Marketo's platform doesn't seem to support this for LP...however, most of the pre-built templates for sale are built to call external css sheet.
What are the steps for proper importing of an html-based template for landing pages? How can I vet a template's specs before I buy it to make sure it will work?
