Resets the CSS padding to zero on all sides.

Returns ​

this

This component, for method chaining.

Remarks ​

Companion to setPadding. Writes "0px 0px 0px 0px" rather than removing the property — preserves the legacy setPadding(null) behaviour as a reset, not a CSS-level clear.

Returns ​

null | number

The baseline offset in pixels, or null when this component has no intrinsic baseline (e.g. graphical or non-text components).

Remarks ​

The default implementation returns null. Subclasses with a meaningful baseline override this method, typically composing an inner baseline with the component's own chrome via wrapInnerBaseline. Used by horizontal layouts to align children of mixed heights so their text baselines coincide. Components that return null are treated as if their bottom edge were the baseline (CSS replaced-element behaviour).

Parameters ​

value ​

string

A CSS white-space value (e.g. "nowrap", "normal", "pre").

Returns ​

null | string

Returns ​

this
