移动端开发问题整理

1.微信端header标签中的文字默认显示变模糊，点击文字后变清晰

<header class="header-1 clearfix">
    <h1>校园招聘</h1>
    <input class="header-1-input" type="text" placeholder="关键字" />
    <a class="header-1-search" href="javascript:void(0);"></a>
    <a class="header-1-r-home" href="index.html"></a>
</header>

css代码：

.header {  position: fixed; left: 0; top: 0; z-index: 400;  100%;height: 51px; background-color: $sq_blue; color: $sq_white; text-align: center; line-height: 51px;
  h1 { font-size: 18px; white-space: nowrap;}
}
.header-l-back { display: block; position: absolute; left: 0; top: 0;  51px; height: 51px; overflow: hidden; text-indent: -999px; }
.header-l-back:after { content: ''; display: block; position: absolute; left: 18px; top: 50%; margin-top: -8px; z-index: 10;  14px; height: 14px; border-top: 1px solid #fff; border-right: 1px solid #fff; transform: rotate(-135deg); -ms-transform: rotate(-135deg); -moz-transform: rotate(-135deg); -webkit-transform: rotate(-135deg); -o-transform: rotate(-135deg); }
.header-r-home { display: block; position: absolute; right: 0; top:0;  70px; height: 51px; overflow: hidden; background: url("../stylesheets/images/home-icon.png") no-repeat center;}
.header-my { margin-right: 60px; height: 51px; line-height: 51px; margin-left: 4.9%;
  a {  49.9%; height: 36px;margin-top: 7px; line-height: 36px; font-size: 18px; }
}
