        </div>
    </div>

    <div class="footer">Footer div</div>
</body>

</html>

When I run page, it displayed like this

Untitled.png

Footer is invisible.

When Page runs then header and footer must be displayed and content div must have a scroll to see complete data from A to Z.

Please help

Take:

overflow: hidden;

off the html/body rules.

@diafol - he will get then 2 scrollbars.

OP - I asume you want a header at the top and a footer at the bottom and the space inbetween is for the content which gets a scrollbar when it overflows.
The reason why your footer is invisble (off-screen) is because you set a heaight on the container of 100vh which pushes the footer down off-screen (or below the fold) and because you have overflow hidden on the html and body it's invisble.

An easy fix for this would be to set a height with calc on that container:
height: calc(100vh - 200px );
That 200px is the height of the header and the footer together.

There's also a way to do this without calc so that you have better browser support (old IE), but it uses fixed positioned header and footer which might give you issues on older touch screen devices. Fixed positioned elements gave disastrous scrolling behaviors on them :)
