When using the padding property; are you allowed to use negative values?

The padding property in CSS is used to create space between an element's content and its border, effectively controlling the internal spacing. Importantly, padding values cannot be negative. This is a fundamental rule of CSS design. When you try to apply negative values to padding, they will be ignored, meaning that the layout of the element will not change as a result of trying to reduce the padding into negative space.

Using negative padding could lead to unexpected behaviors, such as overlapping elements, but since negative padding is not valid, the browser simply reverts to a zero value instead. This behavior ensures that designers can rely on padding to always create the intended spacing without the complications that negative values would introduce.

Other options suggesting that negative values might be accepted are incorrect because they do not align with the defined behavior of the CSS specification. Padding should only have positive values or zero, ensuring proper spacing and layout consistency across different browsers.
