Horizontal sidebar on mobile page version

Hey! I'd like to point out that the _"Get coordinates using button.getBoundingClientRect() for this button"_ button is making this page have a horizontal sidebar on mobile devices.

This isn't ideal since this is the only element that overflows the maximum width of mobile devices display.

What I'd suggest is resizing this button for mobile users, such that the button would fit the page. This can be achieved through CSS, setting up a maximum width of the button on mobile screens, the text will overflow to the next line.

定位包含“Get coordinates using button.getBoundingClientRect() for this button”按钮的页面，并检查其在移动端宽度下的 CSS。在窄 viewport 中检查该页面；当按钮适合屏幕、其文本可以换行且不再存在水平溢出时，即表示完成。
