Mobile view of the contact page bug - html

Question

just such a problem – my contact page has a view bug when in the mobile view – the footer is aroused almost all over the screen and the contact form is on itsee screenshot, I marked the div that obviously causes problems . Checked all the HTML tags – they're OK, tried position of the objects in the CSS – nothing helps. In the desktop view everything looks OKsee screenshot. Here is the HTML document and a CSS file linked there. They are better to copy to an editor to run in a browser.
