Responsive theme doesn't fully adapt mobile screen

Hello,

I use a responsive directory theme v4.6. I resized browser and also tested it with online iPhone simulator. As you can see on the screenshot, for example on the home page, text in listings nor images don’t adapt to the size of the screen. Same goes for logo and such. They just go out (text always and images when mobile is vertically positioned) and additional scrolling to the side is needed. I use several other responsive themes (other then premiumpress) and they all fully adjust to the size of the screen…text wraps as needed, images resize etc. For example the ones that use bootstrap framework. Is there any way I can achieve that here?

Thank you.
