Frequently asked questions
- Can I paste the result straight into my stylesheet?
- Yes. The gradient, box-shadow and cubic-bezier pages write the CSS declaration itself, ready to copy, and the colour converter gives the same colour in each CSS notation.
- Which contrast standard does the checker use?
- WCAG 2: it shows the contrast ratio and whether a pair passes AA and AAA for body text, large text and interface elements.
- Why do some cards lead to another site?
- The palette generator, the colour picker and the favicon maker work on images, so they are on Nouplo’s image site; SVG conversion is on the converter site and lorem ipsum on the text site. The cards say where they lead.
- Are my images uploaded?
- No. Images opened to pick colours or make a favicon are read in your browser and never leave your device.
