STUCCO template set up

Hello does some one know how to change marging size of template.

If someone know this template enouth please give me advice (help)

To change size of margin in first image. Try going to css/build/front-page.less, line 309 (.home-middle) change ‘padding-bottom’ to suit. Not sure where your second image comes from.

Thanks I tried but it doesn’t seems to work.

about your first screenshot, check the class .area-content-accent in your css file, you have a margin-top of 80px + a padding top of 65px.
About the second i do not see this issue on your website.
