我正在寻找一种在选择答案后在问答游戏中禁用按钮（答案）的方法。 我也在寻找一种方法来禁用计数器在选择答案后递增。 还有一个问题是我尝试将 fontawesome.com 和其他网站链接起来使用一个简单的图标，但由于某种原因我只得到空方块。
我不知道为什么我无法使用禁用属性！！帮助你

Hue is a degree on the color wheel from 0 to 360. 0 is red, 120 is green, 240 is blue.
Saturation is a percentage value; 0% means a shade of gray and 100% is the full color.
Lightness is also a percentage; 0% is black, 100% is white.
correct syntax hsl(h, s%, l%)

we use hue to have more control over all color attributes separately

所有设置禁用属性的行都用“//”注释掉。
所有设置禁用属性的行都尝试加载元素“btn”，但 ID 字符串需要匹配您要禁用的实际元素，例如“开始-btn”。
要更改诸如禁用计数器之类的行为，请将增加计数器的代码包装在 if (ShouldCount) { [此处增加的代码] } 条件中。当发生需要停止计数器的事情时，将 ShouldCount 设置为 true 并将其设置为 false；当发生需要重新启动计数器的事情时，将其设置为 true。
我不知道您想用 FontAwesome 做什么，但您应该提出个别问题，而不是在一个问题中提出所有问题。
