Enhancement: reduce the inline style

[mortalYoung]

Intro

I wanna change the background of thumb, but this style is an inline style so that I can't rewrite it.

virtual-list/src/ScrollBar.tsx

Lines 209 to 227 in 00915b4

	<div
	ref={this.thumbRef}
	className={classNames(`${prefixCls}-scrollbar-thumb`, {
	[`${prefixCls}-scrollbar-thumb-moving`]: dragging,
	})}
	style={{
	width: '100%',
	height: spinHeight,
	top,
	left: 0,
	position: 'absolute',
	background: 'rgba(0, 0, 0, 0.5)',
	borderRadius: 99,
	cursor: 'pointer',
	userSelect: 'none',
	}}
	onMouseDown={this.onMouseDown}
	/>
	</div>

Maybe you could use !important
