Filters apply to the element itself, but backdrop-filter applies to whatever is *behind* it.
- →Glassmorphism: Combine a semi-transparent background with a
blur()backdrop-filter to create the 'frosted glass' look popular in modern OS design. - →drop-shadow() vs box-shadow: Use
drop-shadow()as a filter when you want the shadow to conform to a transparent image's non-rectangular edges.
?Frequently Asked Questions
What is CSS Grid?
CSS Grid is a powerful two-dimensional layout system that allows you to design complex web pages using rows and columns, offering more control than Flexbox for full-page layouts.
What does 'fr' mean in CSS Grid?
The 'fr' (fractional) unit represents a fraction of the available space in the grid container. For example, '1fr 1fr' creates two columns of exactly equal width.
Can I use Flexbox and Grid together?
Absolutely. A common practice is using CSS Grid for the overall page layout (macro-layout) and Flexbox for aligning elements inside specific components (micro-layout).
