Frequently Asked Questions
What's the difference between border and outline?
Border is part of the box model and affects layout, while outline is drawn outside the element without affecting layout. Outlines are ideal for focus indicators.
Can I use multiple box shadows?
Yes! Multiple box shadows are comma-separated. They're rendered from top to bottom (first shadow on top). This is useful for complex effects like neumorphism.
How does border-image work?
Border-image slices an image into 9 sections (like a tic-tac-toe grid) and applies them to the border. The 'slice' property defines where to cut, and 'repeat' controls how middle sections are displayed.
What's the best way to style focus states?
Use outline with positive offset for external focus rings, or combine border changes with box-shadow for custom focus styles. Always ensure sufficient contrast for accessibility.
Can I use different border-radius for each corner?
Yes! Switch to 'Individual Corners' mode to control each corner separately. This is useful for creating asymmetric designs or directional elements.
