为没有滚动条的100%高度网格设置边距或填充

我有一个网格布局。我想在它周围添加一个5倍的边距，但这样做会添加一个滚动条。

是否可以在不添加滚动条的情况下设置边距？

function toggle() {
document.querySelector(".container").classList.toggle("withMargin");
}

html,
body,
.container {
height: 100%;
margin: 0;
}
.container {
display: grid;
grid-template-rows: 50px 1fr 1fr;
grid-template-columns: 300px 1fr 1fr;
gap: 5px 5px;
grid-auto-flow: row;
grid-template-areas: "logo header header" "nav-one main main" "nav-two main main";
background-color: black;
}
.main {
grid-area: main;
background-color: lightcoral;
}
.logo {
grid-area: logo;
background-color: lightcyan;
}
.header {
grid-area: header;
background-color: lightgoldenrodyellow;
}
.nav-one {
grid-area: nav-one;
background-color: lightgray;
}
.nav-two {
grid-area: nav-two;
background-color: lightgreen;
}
.container.withMargin {
margin: 5px;
}

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<div class="container">
<div class="main">
<br /><button onclick="toggle()">toggle .container margin</button>
</div>
<div class="logo">logo</div>
<div class="header">header</div>
<div class="nav-one">nav one</div>
<div class="nav-two">nav two</div>
</div>
</body>
</html>

选择器.container.withMargin:使用padding而不是margin

.container.withMargin {
padding: 5px;
}

并为.container选择器添加box-sizing: border-box。

function toggle() {
document.querySelector(".container").classList.toggle("withMargin");
}

html,
body,
.container {
height: 100%;
margin: 0;
}
.container {
display: grid;
grid-template-rows: 50px 1fr 1fr;
grid-template-columns: 300px 1fr 1fr;
gap: 5px 5px;
grid-auto-flow: row;
grid-template-areas: "logo header header" "nav-one main main" "nav-two main main";
background-color: black;
box-sizing: border-box;
}
.main {
grid-area: main;
background-color: lightcoral;
}
.logo {
grid-area: logo;
background-color: lightcyan;
}
.header {
grid-area: header;
background-color: lightgoldenrodyellow;
}
.nav-one {
grid-area: nav-one;
background-color: lightgray;
}
.nav-two {
grid-area: nav-two;
background-color: lightgreen;
}
.container.withMargin {
padding: 5px;
}

<!DOCTYPE html>

<div class="main">
<br />
<button onclick="toggle()">toggle .container margin</button>
</div>

<div class="nav-one">nav one</div>
<div class="nav-two">nav two</div>
