Showing up as Not Mobile friendly on Google’s Test

Hi I am getting errors trying to get google to recognize my site www. mattiasd.be searching for Keywords like 'mattiasd' or 'ligconcert' I just did the Google search console test and it says my site www.mattiasd.be is not mobile friendly. The following problems were found on your site: Content larger than the screen Selectable elements too close together (Portfolio Section) Text too small to read We recommend that you resolve these issues as soon as possible to allow for optimal experience and reach in Google Search. My site looks fine on mobile so I don't know why i get this result.... Please can you help me out? Mattias
