Frequently Asked Questions
Are the generated CSS values cross-browser compatible?
Yes. All generated CSS uses standard properties supported by all modern browsers (Chrome, Firefox, Safari, Edge). Vendor prefixes are included where still needed, such as -webkit-linear-gradient for older Safari.
Can I use the colour palette tool with my own brand colours?
Yes. Enter your brand's hex colour code in the Color Palette tool and it will generate complementary shades, tints, and harmonious accent colours based on colour theory.
What meta tags does the Meta Tag Generator produce?
It generates standard Open Graph (og:title, og:description, og:image), Twitter Card, and core HTML meta tags. Paste the output into your <head> section to improve social sharing previews and SEO.
