我想出了以下 css,它创建了一个 100% x 1 高线 - 基本上是一个带有样式的复制 hr。末端逐渐变为中心的灰色。在最新的 chrome、ff、opera、ie10 和 ie9 上完美运行。对于 ie7 和 ie8,它根本没有显示任何内容。我到底做错了什么?
<!DOCTYPE html>
<!--[if lte IE 8 ]> <html class="ie8" lang="en-US"> <![endif]-->
<!--[if IE 9 ]> <html class="ie9" lang="en-US"> <![endif]-->
<!--[if (gt IE 9)|!(IE)]><!--> <html lang="en-US"> <!--<![endif]-->
并仅使用“”来显示该行。
