It is recommended that you not define a width on this at all, since it will be as wide as the text that fills the button, no matter what browser-defined font size the user picks.
建议你不要定义这个的宽度，因为这个会与填充按钮的文本宽度相同，不管用户选择的浏览器定义的字体大小是多少。
You can preview the font in different font styles and colors, or even anti-aliasing, the use of user-defined sample text.
您可以预览字体不同的字体样式和颜色，甚至反走样，使用用户定义的示例文本。
