I'm trying to make a calculator and am currently working on HTML and CSS. I'm trying to make the calculator larger both vertically and horizontally. I can easily increase the width to fit the container using width: 100% or flex: 1 1 100%; however, whenever I try to increase the height with height: 100%; it goes outside the bounds of the container and the input button becomes huge. I've tried using flex-basis and flex-grow to make it grow vertically as well, but I can't.

<div class="container">
<form>
<div class="display">
<input type="text" name="display">

<div class="column1">
<input type="button" value="AC">
<input type="button" value="+/-">
<input type="button" value="%">
<input type="button" value="/">

<div class="column2">
<input type="button" value="7">
<input type="button" value="8">

<input type="button" value="*">

<div class="column3">

The following is the specific operation method:
.container{ /* height: 50%; */ width: 100%; } .column1, .column2, .column3, .column4, .column5, .display{ height: calc(100vh/6); /* Distributing the viewport height within 6 columns */ }
