Question

我有一个JavaScript视频播放器控件，我需要在用户放大视频时保持播放时间和时间总计，或者使屏幕大于1500px宽。不确定我是否应该使用媒体查询或将CSS附加到文本类的jQuery，以确保文本不会超出范围并在窗口放大或缩小时覆盖控件。

jQuery用于控制播放器图标/文字

    $('document').ready(function () {
    // resize on dom ready
    resizePlayer();

    // add window resize binding
    $(window).resize(resizePlayer);
});

function resizePlayer() {
    var newWidth = $('.timeline').outerHeight() * 0.25;

    var containerSize = $('.timeline').width();
    var textPercentage = 0.57391304347826086956521739130435; /* 40/230 */
    var textRatio = containerSize * textPercentage;
    var textEms = textRatio / 244;

    $('.play, .pause, .mute, .fullscreen').width(newWidth);
    $('.time-played, .timeline, .time-total').css('fontSize', textEms+"em");
}

CSS

    body {
    background-color: #000;
}
 .video-controls {
    position: absolute;
    background: #fff;
    z-index: 2147483647;/*has to be here for full screen*/
    /* default min-height */
    height: 12%;
    bottom: 0;
    left: 0;
    right: 0;
    margin: auto;
    min-width:500px;
  }

  .video-controls .container-fluid {
    position: relative;
    left: auto;
    top: 50%;
    margin-top: -14px;
    height: 28px;
    line-height: 28px;
    width: inherit;
  }

  /* button & button alignments */

    top: 39%;
    right: -47px;
    font-size:14px;
    color: #000;

.timeline .time-played {
    position: absolute;
    top: 39%;
    left: -37px;
    font-size:14px;
    color: #000;

.timeline-progress, .timeline-total {
    height: 1px;
    position: absolute;
    top: 50%;
    left: 0;
}
.timeline-total {
    width: 100%;
    /*background: rgba(255,255,255,.22);*/
    z-index: 1;
}
.timeline-progress {
    width: 24%;
    background: #fff;
    z-index: 2;
}

您正在使用此js：

按比例更改字体大小

$('.time-played, .timeline, .time-total').css('fontSize', textEms+"em");

但包含不会改变其大小或位置。如果删除此行代码，您将看到时间保持不变但不会更改大小。如果使用此脚本更改字体大小非常重要，则还需要调整div的位置。

保持视频播放器控制文本的位置
