What are CSS Modules and why do we need them?

What does this look like and why do it? We’ll get to that in a sec. First, remember how HTML and CSS normally work. A class is applied in HTML:

<h1 class="title">An example heading</h1>

And that class is styled in CSS:

.title {
  background-color: red;
}

As long as that CSS is applied to the HTML document, the background of that <h1> would be red. We don’t need to process the CSS or the HTML. The browser understands both those file formats.

Pleyel et Cie

Pleyel et Cie (“Pleyel and Company”) was a French piano manufacturing firm founded by the composer Ignace Pleyel in 1807. In 1815, Pleyel’s son Camille joined him as a business partner. The firm provided pianos to Frédéric Chopin, and also ran a concert hall, the Salle Pleyel, where Chopin performed his first – and last – Paris concerts. Pleyel’s major contribution to piano development was the first use of a metal frame in a piano. Pleyel pianos were the choice of composers such as Debussy, Saint-Saëns, Ravel, de Falla and Stravinsky and of pianists and teachers Alfred Cortot, Philip Manuel and Gavin Williamson. Nineteenth-century musicians involved in the company’s management included Joseph O’Kelly and Georges Pfeiffer.
