I'm very new to wordpress and I'm still getting my head around this. So, I'm using twentyseventeen theme but I want my front page to be just a landing page with my logo and a button to press 'Go', I dont need neither header or footer.
My idea is to copy front-page.php to my child theme folder and, being there, I change the code at my will, like removing the footer caller and the navigation menu, add the background color that I want, etc. Will I have problems with updates and is that a good practice? Because by doing this I'm basically changing all front-page code. Should I, instead, try to apply filters in the functions.php and use the style.css to, for example, hide the navigation menu?
