需求：
客户想要打印网页内容，而打印的数据都是黑白现实的的，不需要其他颜色，需要给客户设置打印样式
那，如何满足需求？
设置一个打印媒体查询
/* 打印样式 ??========================================================================== *//** */@media print { ???*, ???*:before, ???*:after { ???????background: transparent !important; ???????color: #000 !important; ???????box-shadow: none !important; ???????text-shadow: none !important; ???} ???a, ???a:visited { ???????text-decoration: underline; ???} ???a[href]:after { ???????content: " (" attr(href) ")"; ???} ???abbr[title]:after { ???????content: " (" attr(title) ")"; ???} ???/*使用JavaScript的超链接不打印href*/ ???a[href^=‘#‘]:after, ???a[href^=‘javascript:‘]:after { ???????content: ‘‘; ???} ???pre, ???blockquote { ???????border: 1px solid #999; ???????page-break-inside: avoid; ???} ???thead { ???????display: table-header-group; ???} ???tr, ???img { ???????page-break-inside: avoid; ???} ???img { ???????max-width: 100% !important; ???} ???p, ???h2, ???h3 { ???????/*当标题和文字不分离，3行文字以上带走标题进入下一页*/ ???????orphans: 3; ???????widows: 3; ???} ???h2, ???h3 { ???????page-break-inside: avoid; ???}}
