I recently joined a company working on Marketo, it's pretty new for me. I dono bootstrap and very well versed with hard coding the responsive landing page and email templates, but when I look into my design studio they've LP templates created using bootstrap. Now I got a new request where am done with coding the LP but not sure how to create Template in Marketo using that. Email templates are easy but LP is making me crazy. Kindly help me with any docs or training videos on LP landing page build and adding the page elements to it.
