Create Content

You can create a div element an set the content.

We use the document method createElement and the DOM node method append

let e = document.getElementById('countries');
e.style.background = 'pink';
let e = document.getElementById('countries');
e.style.background = 'gray';

Create img

You can create a img element an set the src. In this example you must set the src and the style of the new element a.

a.style = 'width:100px;border:solid;';

These are CSS properties.

let a = document.createElement('img');
a.src = '/flags/fr.png';
document.body.append(a);
let a = document.createElement('img');
a.src = '/flags/fr.png';
a.style = 'width:100px;border:solid;';
document.body.append(a);
