用CSS实现音乐播放进度条的问题

求教：想用css实现一个显示音乐播放进度条的效果，这里为什么连个矩形都画不出来？

<div id="bottom">
        <img class="icon" id="rewind" src="./assets/icons/rewind.png"></img>
        <img class="icon" id="play" src="./assets/icons/play.png"></img>
        <img class="icon" id="pause" src="./assets/icons/pause.png"></img>
        <img class="icon" id="forward" src="./assets/icons/forward.png"></img>
        
        <span id="currentTime">00:00</span>
        <div id="time_move"></div>
        <img src="./assets/icons/dot.png" id="process_img"></img>
        <span id="totalTime">00:00</span>
            
    </div>

inline元素是不能设宽高的，改成inline-block
