问题

I am having trouble with my footer. I want the footer to stay at the bottom of the screen, but there is a slight problem. When using mobile browser, some fields get blocked by the footer when opening the keyboard. The footer rises over the keyboard and blocks the field you are typing in. How can I keep my footer at the bottom and prevent it from rising over the keyboard? I want it to stay hidden under the keyboard.

I am using bootstrap, but I have set the following stuff in my own CSS:

footer {
 width: 100%;
 position:absolute;
 left:0px;
 bottom:0px;
 height: 40px;
 margin: auto;
 overflow: hidden;
 background:#2E2E2E;
 text-align:center;
 line-height: 15px;
 color: #fff;

}

<html>
 <body>
  <div class="container">
  </div>
  <footer class="bs-footer" role="contentinfo">
 </body>
</html>

As you can see here. When I am activating the field "Salasana", the footer rises and blocks the text field.

Solved the problem with avinash help. I ended up changing the following in my CSS. Since I have all the content inside the container div I made container height 100% - footer. I also removed bottom:0px from footer.

footer{
 position: relative;
}
html,body {
    height: 100%; /* Needed for container's min-height  */  
}

.container{
    min-height:100%;
    margin-bottom: -40px; /* Put negative height of the footer here */
    padding-bottom: 40px; /* Put height of the footer here. Needed for higher than screen height pages */
}

I found the solution posted here on StackOverflow to be pretty helpful. It includes a javascript snippet that solved the issue for me, pasting below;

if(/Android [4-6]/.test(navigator.appVersion)) {
   window.addEventListener("resize", function() {
      if(document.activeElement.tagName=="INPUT" || document.activeElement.tagName=="TEXTAREA") {
         window.setTimeout(function() {
            document.activeElement.scrollIntoViewIfNeeded();
         },0);
      }
   })
}

Try to use position:relative or fixed

If you want your footer at bottom you should add min-height to body

In case you don't want to change html code, you can try fix this with JS.

We are getting current position from top, setting the top style value, and resetting bottom value.

var fixed = document.querySelector(".fixed"),
    distanceFromTop = fixed.getBoundingClientRect().top;
fixed.style.top = distanceFromTop + 'px';
fixed.style.bottom = 'auto';
