const rainbowBackground = RainbowBackground.init(colors, className = 'rainbow-background');

其中，colors是一个包含所有颜色的数组，至少传入2个色值，例如：['#0000ff', '#0080ff', '#00ffff', '#80ff80', '#ffff00', '#ff8000', '#ff0000', '#800000']

如果调用多次init()方法，且className相同，那么样式将被覆盖

rainbowBackground.addTo(element);

rainbowBackground.removeFrom(element);

rainbowBackground.getCSSCode();

rainbowBackground.getCSSText();

在直播时需要吸引眼球的背景效果

在录制视频时需要特殊风格的文字，和普通的字幕区分开

根据主题，不同的网站往往需要不同的文字风格
