字体 颜色 行距与网页易读性
对字体和颜色的正确利用可以使你的网站更具备可读性。
留意对比色黑字白底，或者是白字黑底，对于有视觉障碍的人或者是显示设备不是太好的人来说是最佳的颜色组合方案。
灰字亮色底的对比效果非常差：
| Grey text on a white background (#EEEEEE) |
| Grey text on a white background (#CCCCCC) |
| Grey text on a white background (#AAAAAA) |
| Grey text on a white background (#888888) |
| Grey text on a white background (#666666) |
| Grey text on a white background (#444444) |
| Grey text on a white background (#222222) |
| Grey text on a white background (#111111) |
Grey text on a dark background can also give a very poor contrast:
灰字深色底的对比效果同样也很差：
| Grey text on a black background (#222222) |
| Grey text on a black background (#444444) |
| Grey text on a black background (#666666) |
| Grey text on a black background (#888888) |
| Grey text on a black background (#AAAAAA) |
| Grey text on a black background (#CCCCCC) |
| Grey text on a black background (#DDDDDD) |
| Grey text on a black background (#EEEEEE) |
Some combinations - like black and red, black and blue, yellow and green - always strain the eye:
一些颜色组合 - 如：黑红组合、黑蓝组合、黄绿组合 - 通常会让人产生视觉疲劳
| Black text on a red background |
| Black text on a blue background |
| Yellow text on a green background |
And some combinations are not so bad:
然而，有些颜色组合就不错：
| Black text on a grey background |
| Black text on a light blue |
| Black text on antique white |
| White text on dark blue |
