How to make content in my Web App to not resize when keyboard on the phone shows up?

  Kiến thức lập trình

guys! I am building web app using Vue. I have an input in my app. When I’m testing it on mobile device (Android) and my keyboard appears, the whole content of the app goes above appeared keyboard and app becomes small (in my css I am using responsive metrics to make design be great looking on all devices). So how can I make content of my app totally ignore appearing keyboard? Just do nothing, keep its sizes same and ignore keyboard/viewport changes?
