Home page settings

Hi, I have a few questions regarding the settings on the home page: 1. Is it possible to change the 'sequence'/order of the elements that are on the home page? Now, on my website you have the page slider, projects and then a text (from top to bottom). I would like to change these elements, in the following order: page slider - text - projects. 2. Is it possible to have a separate image for featured pages for responsive use (mobile devices)? Currently, the website looks properly on a laptop or desktop computer, yet on mobile devices the 'featured images' do not make sense at all. See attachment. You do not see any useful image. The settings for customizer --> theme options --> featured slider --> 'mobile display' does not give me the right result. I would like to have a different image for mobile devices. Is this possible with a simple custom CSS code? 3. How can I remove the 'search icon' at the upper right corner of my screen? For my website it doesn't make sense to have a 'search icon'. I found several topics for this question, but the custom CSS code doesn't work: #search-toggle { display: none; } 4. I would like to delete the 'dates' when you hover over the project images. I just want to see the title. Is that possible? My website is: http://studiovandriessche.nl/ Many thanks in advance.
