我有以下具有内部跨度的div：

<!-- Debug info -->
        <div class="helperInfo" ng-if="learningModeState == true">
            <span ng-if="activeCandle != null">Active candle : {{activeCandle}} |</span>
            <span ng-if="activeCandle == null">Active candle : 0 |</span>
            <span ng-if="selectedCandle != null">Selected candle: {{selectedCandle}} |</span>
            <span ng-if="selectedCandle == null">Selected candle: None |</span>
            <span>Volume: {{micVolume}} |</span>
            <span>Treshold: {{micTreshold}} |</span>
        </div>

和相关CSS：

.helperInfo {
    position: absolute;
    width: 100%;
    bottom: 0%;
    height: 8%;
    text-align: center;
}

.helperInfo span {
    font-size: 150%;
    color: #fff;
    text-align: center;
}

问题是字体大小是良好的分辨率约640 x 320在横向，但如果我试图设置的分辨率设备，例如1920 x 1080，我总是得到的字体小于640 px分辨率（见下图）。

我应该设置什么以得到相同的尺寸和比例的不同的尺寸？

视口设置为：

<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">

车身：

body {
    background-color: #000000 !important;
    font-size: 16px;
}

整个模板为：

<ion-view class="gameBgImage" >
    <ion-content ng-init="animateGameScreen()" scroll="false" >

        <!-- Debug info -->
        <div class="helperInfo" ng-if="learningModeState == true">
            <span ng-if="activeCandle != null">Active candle : {{activeCandle}} |</span>
            <span ng-if="activeCandle == null">Active candle : 0 |</span>
            <span ng-if="selectedCandle != null">Selected candle: {{selectedCandle}} |</span>
            <span ng-if="selectedCandle == null">Selected candle: None |</span>
            <span>Volume: {{micVolume}} |</span>
            <span>Treshold: {{micTreshold}} |</span>
        </div>
