在CSS中响应移动

Question

我试图让我的底部表格响应移动和桌面。你可以在笔记本电脑看到下片当你点击新主题它工作一切正常：

但随后让我们看看它的移动版本（定期iPhone 5）：

你可以看到它的超越可怕的......我的HTML对于视图（最小化）：

<div class="toolbar_new_topic" ng-if="authDataDesc!=null"> 
    <md-button id="NEW_TOPIC_BUTTON" ng-click="showNewTopic($event)"> 
    <ng-md-icon icon="add_box" style="fill: white" size="20" id="add_icon"></ng-md-icon> 
    <span id="text_new_topic" color="white">Create a New Topic</span> 
    </md-button> 
</div>

您需要在CSS中使用媒体查询来定位移动设备大小。例如：

@media (max-width: 420px) { 
    /* your styles here */ 
}
