Leaflet.js：使用CSS将自定义文本添加到图层控件？

I am building an interactive map using Leaflet.js. The out-of-the-box layers panel that comes with Leaflet is difficult to hack. My users have large resolution monitors and they easily miss this little collapsed layers icon. So, what I want to do is add the text "View Overlays" to the right of the icon. Apparently, the icon is also larger than what is shown in the map. It looks like CSS is shrinking it down a little, but I am not sure how to revert the icon size back to its default larger size.I am building an interactive map using Leaflet.
