laTex cv currvita - templates

Question

I found this template and I would like to modify two things but all I tried does not work:
I would like to have more white vertical space before it displays my name since it's too close to the top as it is now
I would like the text of experience (blablablablabla..) to be more wide and therefore to reduce left and right margins
Any ideas on how to modify this template?
Thx

Answer 1

Here is how I addressed your two requirements:
Insert an invisible, vertical strut as part of the \cvheadingfont. I used \rule{0pt}{100pt}, but you can adjust (increase/decrease) the value of 100pt to move the content up/down.
Switched the document class to use the default article class, since there seems to be no need for using KOMA-script. This also allows for ease-of-use when changing the page layout/geometry using geometry. You can adjust the left and right margins to suit your needs.
