Frequently Asked Questions

Common questions about how we use CSS3 and what it can bring to your project. Have a specific requirement?

We use CSS3 to style responsive websites, web applications, and email templates, using Flexbox, Grid, and modern layout features to build clean, consistent interfaces across devices.

What types of projects do you style with CSS3?

We style marketing sites, web applications, dashboards, and email templates, from early-stage MVPs to interfaces supporting established products with complex design systems.

Can CSS3 work alongside our existing HTML and JavaScript?

Yes. CSS3 works alongside HTML and JavaScript as one of the three core web technologies, and can be introduced into an existing codebase without requiring a rewrite.

Do you use Sass or other preprocessors with CSS3?

Yes, we commonly pair CSS3 with preprocessors such as Sass, and with utility or component frameworks such as Tailwind CSS or Bootstrap, depending on the project.

We use media queries, Flexbox, and Grid to build layouts that adapt cleanly across phones, tablets, and desktop screens, without relying on extra JavaScript.

Can you modernize an existing stylesheet with CSS3?

Yes. We can refactor a legacy stylesheet into modern CSS3 gradually, section by section, or rebuild it from scratch, depending on your timeline and current codebase.

How do you decide whether CSS3 fits a project?

We look at your design requirements, target devices, existing codebase, and team skillset, then confirm the right combination of CSS3 and supporting tools before starting development.
