Question 1

What are CSS filters?

Accepted Answer

CSS filters are visual effects applied to images, videos, or elements using the filter property in CSS. They let you modify brightness, contrast, blur, colors, and more without using image editing software. Common filters include blur(), brightness(), contrast(), grayscale(), sepia(), hue-rotate(), invert(), saturate(), and opacity(). Multiple filters can be combined for complex effects.

Question 2

How do I apply a CSS filter to an image?

Accepted Answer

Add the filter property to your CSS selector. Example: img { filter: blur(5px) brightness(1.2); } This applies a 5-pixel blur and increases brightness by 20%. You can combine multiple filters separated by spaces. This generator creates the exact CSS you need - just copy and paste it into your stylesheet.

Question 3

What is the difference between brightness and contrast?

Accepted Answer

Brightness changes the overall lightness or darkness of the image uniformly (0% = black, 100% = original, 200% = very bright). Contrast increases the difference between light and dark areas (0% = gray, 100% = original, 200% = high contrast). Use brightness to lighten/darken the entire image, and contrast to make details pop.

Question 4

What does the blur filter do?

Accepted Answer

The blur(Xpx) filter applies a Gaussian blur to the element. Higher pixel values create a stronger blur effect. For example, blur(0px) is no blur, blur(5px) is moderate blur, and blur(20px) is heavy blur. Blur is useful for creating frosted glass effects, hiding detail, or creating visual hierarchy.

Question 5

Can I use multiple filters together?

Accepted Answer

Yes! You can chain multiple filters together: filter: blur(2px) brightness(1.1) contrast(1.2) saturate(1.3);. They apply left to right in the order written. This generator lets you adjust multiple sliders and combines them automatically into a single efficient filter string.

Question 6

What is the hue-rotate filter?

Accepted Answer

The hue-rotate(Xdeg) filter rotates colors around the color wheel by X degrees. 0deg is the original color, 180deg inverts colors, 360deg returns to the original. For example, hue-rotate(90deg) shifts green to blue. This is useful for creating color variations or stylized image effects.
