NexusLabs CSS Toolkit — 5 Design Tools од Akash Kumar Singh

Stop switching between websites for everyday design tasks. NexusLabs CSS Toolkit puts 5 powerful, privacy-first styling utilities into a single beautiful popup — right in your browser toolbar.

Whether you need to quickly translate a color between different formats, create a harmonious set of tones, design a smooth background transition, convert between sizing units, or fine-tune a depth effect — CSS Toolkit handles it in one click without leaving your current tab.

✅ What You Can Do

Pick any color and instantly see its value in every common format — hex, RGB, and HSL. Adjust individual channels with sliders, preview the result in real time, and copy the output with one click.

Need a coordinated set of tones? Enter a base color and generate complementary, analogous, triadic, tetradic, shade, and tint variations automatically. Each swatch shows its value and can be copied individually.

Build smooth background transitions by choosing a direction, picking your starting and ending colors, and optionally adding a third stop. Preview the result live and copy the ready-to-use style rule.

Convert between common sizing units — pixels, rems, ems, points, and percentages — with a configurable base size. Type a value in one field and see all conversions update instantly.

Fine-tune depth effects with intuitive sliders for offset, blur, spread, and opacity. Toggle the inset option, pick a shadow color, and preview the result against a live element — then copy the finished style rule.
