I want a checkbox to be checked by default when the page loads, so that a menu bar is initially collapsed (hidden). How can I achieve this using HTML and CSS?
Here is my current HTML and CSS code:
header #toggler:checked ~ .navbar{
clip-path:polygon(0 0, 100% 0, 100% 0, 0 0);
}

header .navbar a{
display: block;
}
!DOCTYPE html

html lang="en"

head
meta charset="UTF-8"
meta name="viewport" content="width=device-width, initial-scale=1.0"
title The CheeseCake Shop /title
link rel="stylesheet" href="style.css"
/head

body

header
input type="checkbox" name="" id="toggler"
label for="toggler" class="fas fa-bars" /label
nav class="navbar"
a href="#home" Home /a
a href="#about" About /a
a href="#products" Products /a
a href="#contact" Contact /a
/nav
/header

/body

/html
header #toggler:checked ~ .navbar{
clip-path:polygon(0 0, 100% 0, 100% 0, 0 0);
}

header .navbar a{
display: block;
}
!DOCTYPE html
