Answer 1

At the top of your css styles add this:

html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
b, u, i, center,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td,
article, aside, canvas, details, embed, 
figure, figcaption, footer, header, hgroup, 
menu, nav, output, ruby, section, summary,
time, mark, audio, video {
    margin: 0;
    padding: 0;
}

You should always do a reset at the top of your styles

Answer 2

I've answered on another question with same issue.

But I'll answer it here also:

body {
  min-height: 100vh;
  min-height: -webkit-fill-available;
}
html {
  height: -webkit-fill-available;
}

-webkit-fill-available;

makes the "magic"

Answer 3

That looks like iPhones input zoom feature causing that padding...

Check the answers here: Disable Auto Zoom in Input "Text" tag - Safari on iPhone

It seems setting the input field font to 16px disables this feature.

Answer 4

I don't think this is solvable with CSS, it seems to be Safari chrome.

When I test it on an actual device (6+) the space at the bottom is white. I played with some :focus styles with positioning, and found I was only cutting off the container.

#textarea:focus {
  border-bottom: 14px solid red;
  bottom: -6px; //shows 1px of border
  //bottom: -7px; //shows no border
}

As far as a solution goes this is a design problem, I wonder if there's a way that you can use this white space to your advantage. Users will be focussed on what they're entering, you can make this look good :)
