How to remove the page titile / edit style of page?

is there a way to remove the page title from one of my pages? I am using a page called "Welcome" for a static front page as i don't want the one that came with the theme.

As well as removing the title i would like to change the template of the page, currently it is set to full page: although it is not really full page, it is centered and maintains the same size on all screens sizes is there a way to increase it while keeping it responsive. currently if the page shrinks it also proportionally shrinks which is good.

So in summary i want to Edit the style of the page: removing the title name and spacing. While also editing the size of the page so that the maximum size increases to fit the page while still keeping the responsive feature so when the screen sizes are smaller it is still the maximum available of the screen. is that possible?
