CSS stands for Cascading Style Sheets. It controls how a web page is presented: spacing, color, typography, layout, and many visual effects. HTML supplies the structure and content; CSS gives that structure its visual treatment.
What that means for a business website
The same service information can feel crowded or easy to browse depending on its styling. A readable line length, a clear button, and enough space between sections are small decisions that shape the experience. CSS also helps layouts adapt to different screen sizes.
A shared design system lets repeated elements follow consistent rules. If the brand color changes, a well-organized theme can reuse a central value instead of requiring a separate edit to every button. That is one reason we care about the structure behind a design as well as its appearance.
Custom does not have to mean complicated
For Carrier Lynx, custom icons and hover animations added character to a deliberately simple website. The effect had a specific visual purpose. An animation is less helpful when it distracts from reading or makes a control hard to use.
When reviewing a design, test the quiet states too: the page on a phone, navigation with a keyboard, and the experience for someone who prefers reduced motion. Useful styling supports those situations.
