我有一个酒吧的页脚:

<div class="crop modal">
    <div class="crop-center-container">
        <div class="crop-img" ng-style="{width: width + 'px', height: height + 'px'}"></div>
    </div>
    <div class="crop-center-container">
        <div class="crop-select" ng-style="{width: width + 'px', height: height + 'px'}"></div>
    </div>
    <div class="bar bar-footer bar-dark">
        <div class="button-bar">
            <button class="button button-clear crop-button icon ion-ios-close" ng-click="cancel()"></button>
            <button class="button button-clear crop-button icon ion-ios-undo"></button>
            <button class="button button-clear crop-button icon ion-arrow-left-a"></button>
            <button class="button button-clear crop-button icon ion-ios-redo"></button>
            <button class="button button-clear crop-button icon ion-ios-checkmark" ng-click="crop()"></button>
        </div>
    </div>
</div>

我将字体大小设置为50px,但没有任何更改。我无法更改图标的大小。如何更改它们?

这是因为中间没有文本,所以无法设置字体大小


这里有文本我们看不到你的图标,添加更多的cssWorks好吧,你可能还缺少其他东西。我发布了完整的html和css。在爱奥尼亚,按钮可以用作图标,中间没有文本。给字体大小设置样式可以改变图标的大小。
