What is CSS?
CSS, in plain English.
CSS, short for Cascading Style Sheets, is what makes a website look like your brand. It controls colors, fonts, spacing, layout and the small animations that make a page feel polished. Without it, every site would look like a plain text document.
It also does the heavy lifting on different screen sizes. One set of CSS rules can arrange a page in three columns on a laptop and stack it neatly on a phone, so you do not need a separate mobile site. Because the rules live in one place, changing a brand color or a font can update the whole site at once.
CSS is an open web standard developed by the W3C and free for everyone to use. Well-written CSS also affects speed and search. Lean styles load faster, and a page that works well on mobile is something Google looks for.

Why we use CSS.
CSS is where a design becomes a real site, so we write it carefully. We build styles from shared rules and brand variables instead of one-off fixes. That keeps pages consistent, quick to load, and simple to adjust when your brand changes.
Consistent Branding
One set of rules keeps colors and fonts the same on every page.
Looks Right Everywhere
Layouts adapt to phones, tablets and desktops without a separate site.
Quick Brand Updates
Change a color or font in one place and the whole site follows.
