Question 1

What does CSS filter do?

Accepted Answer

filter applies graphic effects to the element itself (and its contents): blur, brightness, contrast, grayscale, hue-rotate, invert, opacity, saturate, sepia, and drop-shadow. Default is none.

Question 2

How is filter different from backdrop-filter?

Accepted Answer

filter changes the element. backdrop-filter blurs or tints what’s behind a translucent element. Use this tool for the element; use Backdrop Filter for frosted glass.

Question 3

Can I stack multiple effects?

Accepted Answer

Yes. Non-default values are combined in order. Add one or more drop-shadow layers separately. Only active functions appear in the copied CSS.

Question 4

Do I need -webkit-filter?

Accepted Answer

Modern browsers support filter. Enable -webkit-filter in the panel if you still need broader Safari / legacy WebKit coverage — both declarations are included in the output.

Question 5

What is an HTML color code?

Accepted Answer

An HTML color code is a way to specify colors in web pages using HEX (#RRGGBB), RGB, HSL, or named CSS colors. HEX is the most common format in CSS and HTML.

Question 6

How do I convert HEX to RGB?

Accepted Answer

Use our HEX to RGB converter. Paste a HEX value like #FF5733 and get rgb(255, 87, 51). You can also convert RGB back to HEX with the RGB to HEX tool.
