โปรแกรมแก้ไข Box Shadow ขั้นสูง

คำถามที่พบบ่อย

Quick answers.

›How do I create a realistic shadow?

Layering multiple shadows is key. Start with a tight, dark shadow for the base and stack a second, softer shadow with a larger blur and lower opacity for the ambient glow.

›What is the difference between blur and spread?

Blur softens the edges of the shadow using a Gaussian algorithm. Spread increases or decreases the physical size of the shadow source before the blur is applied.

›Does this support inset shadows?

Yes. Each layer can be toggled to `inset`, which places the shadow inside the element's frame to create a sunken or pressed effect.

›Is the CSS compatible with all browsers?

The generated `box-shadow` property is supported by all modern browsers. For very old versions of Safari or Firefox, you may need to add `-webkit-` or `-moz-` prefixes manually.
