I'm doing the leaflet step by step for webmap with javascript, html and css. The internet page is blank when I run the code, but the script doesn't show an error. Please, help

        #map{
            width: 100%;
            height: 100%;
        }

<script>

//inicialização do mapa
var map = L.map('map').setView([-14.23,-51.92], 4);

var osm = L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {

osm.addTo(map);

You need to set a non-zero height on the map div.
height: 100% results in a 0px height for your map div.

One of these rules will work.

  • height: 100vh;
  • height: 400px;
  • height: 50rem;
