我想包括 owencm 对遇到这个问题的人的评论，因为我觉得它很优雅:

CSS

input.holo[type='text'] {
    /* You can set width to whatever you like */
    width: 200px;
    font-family: "Roboto", "Droid Sans", sans-serif;
    font-size: 16px;
    margin: 0;
    padding: 8px 8px 6px 8px;
    position: relative;
    display: block;
    outline: none;
    border: none;
    background: bottom left linear-gradient(#a9a9a9, #a9a9a9) no-repeat, bottom center linear-gradient(#a9a9a9, #a9a9a9) repeat-x, bottom right linear-gradient(#a9a9a9, #a9a9a9) no-repeat;
    background-size: 1px 6px, 1px 1px, 1px 6px;
}
input.holo[type='text']:hover, input.holo[type='text']:focus {
    background: bottom left linear-gradient(#0099cc, #0099cc) no-repeat, bottom center linear-gradient(#0099cc, #0099cc) repeat-x, bottom right linear-gradient(#0099cc, #0099cc) no-repeat;
    background-size: 1px 6px, 1px 1px, 1px 6px; 
} 

HTML

<input type='text' class='holo'/>
