While it looks not much happened, this just simply because we haven’t added a tile layer yet. Var knightMap = L.map('mapid').setView(, 5) Finally, to set the view to be centered on the Knight Lab, (or Fisk Hall) we will give the function the longitude and latitude 42.0507, -87.6742, as well as how close we want to be, 13. It requires the id of the div we want it to render in, so we pass it mapid. The first thing we will do is create a variable, knightMap and call the L.map function that is built into Leaflet. Navigate to the Javascript pane of your CodePen. Remember to use the # sign before the name since we are calling the div by its id. Inside it, create another div, with the id “mapid”.įinally, let’s make sure we will be able to see our map! Navigate to the CSS window on CodePen and beneath the for Google Fonts set the height of the map to be 35vh. Navigate to your Html window pane and find the div, which has the id “map-holder”. Hit “Save and Close” to leave the window. Underneath “Add External Stylesheets/Pens” you should see the link This link is telling CodePen to load in an external javascript file called leaflet.js which contains the javascript that Leaflet’s developers have already created. Hit “Save and Close” to leave the window.Ĭlick on the gear wheel of the Javascript window pane. Underneath “Add External Stylesheets/Pens” you should see the link This link is telling CodePen to load in an external css file called leaflet.css which contains the CSS that Leaflet’s developers have already created. ![]() To use it, we need to import the code its developers have already created.Ĭlick on the gear wheel of the CSS window pane. Leaflet is a javascript library which is focused on interactive maps. ![]() To start, fork the Knight Lab Leaflet Template. In this tutorial, we will create a small interactive map to display information about the Knight Lab as well as its location. This tutorial is an adaption of the Leaflet Quick Start Tutorial for CodePen.
