Why I can't access my website properly on phone?

Hello I have hosted my website on 000webhost free server. Most of the functions are working properly there. But when I access it on my phone, it's not working. If I tap on something keyboard keeps popping up. It's hard for me to find the error. Please someone help me here by accessing my site through a mobile device. Thank you.
