Font Awesome is a convenient library of icons. These icons can be webfonts or vector graphics. These icons are treated just like fonts. You can specify their size using pixels, and they will assume the font size of their parent HTML elements.
You can include Font Awesome in any app by adding the following code to the top of your HTML:
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.1/css/all.css" integrity="sha384-50oBUHEmvpQ+1lW4y57PTFmhCaXp0ML5d60M1M7uH2+nqUivzIebhndOJK28anvf" crossorigin="anonymous">
In this case, we've already added it for you to this page behind the scenes.
The i element was originally used to make other elements italic, but is now commonly used for icons. You can add the Font Awesome classes to the i element to turn it into an icon, for example:
<i class="fas fa-info-circle"></i>
Note that the span element is also acceptable for use with icons.
Use Font Awesome to add a thumbs-up icon to your like button by giving it an i element with the classes fas and fa-thumbs-up. Make sure to keep the text Like next to the icon.
You should add an i element with the classes fas and fa-thumbs-up.
assert.isTrue(document.querySelector('i')?.classList?.value === 'fas fa-thumbs-up' || document.querySelector('span')?.classList?.value === 'fas fa-thumbs-up');
Your fa-thumbs-up icon should be located within the Like button.
const iconTextContent = document.querySelector('i.fa-thumbs-up')?.parentNode?.textContent;
const spanTextContent = document.querySelector('span.fa-thumbs-up')?.parentNode?.textContent;
assert.isTrue(
(iconTextContent?.match(/Like/gi) &&
document.querySelector('.btn-primary > i') === document.querySelector('.fas.fa-thumbs-up')) ||
(spanTextContent?.match(/Like/gi) &&
document.querySelector('.btn-primary > span') === document.querySelector('.fas.fa-thumbs-up')));
Your i element should be nested within your button element.
const button = document.querySelector('button');
const i = button?.querySelectorAll("i");
const span = button?.querySelectorAll("span");
assert(i.length > 0 ||span.length > 0);
Your icon element should have a closing tag.
assert.match(code, /(<\/i>|<\/span>)\s*Like\s*<\/button>/g);
