Thank you for t-p for your answer, but this article does not describe what I’m looking for.
The “old” media player can be split roughly like this, making customization possible:
<div id="" class="mejs-container mejs-container-keyboard-inactive mejs-android mejs-audio" tabindex="0" role="application" aria-label="">
<div class="mejs-inner">
<div class="mejs-mediaelement">
<mediaelementwrapper id="">
<audio preload="" width="" src="" id="" style="">
</audio>
</mediaelementwrapper>
</div>
<div class="mejs-layers">
<div class="mejs-poster mejs-layer" style="">
</div>
</div>
<div class="mejs-controls">
<div class="mejs-button mejs-playpause-button mejs-play">
<button type="button" aria-controls="mep_0" title="" aria-label="" tabindex="0">
</button>
</div>
<div class="mejs-time mejs-currenttime-container" role="timer" aria-live="off">
<span class="mejs-currenttime">00:00</span>
</div>
<div class="mejs-time-rail">
<span class="mejs-time-total mejs-time-slider" role="slider" tabindex="0" aria-label="Curseur de temps" aria-valuemin="0" aria-valuemax="0" aria-valuenow="0" aria-valuetext="00:00">
<span class="mejs-time-buffering" style=""></span>
<span class="mejs-time-loaded"></span>
<span class="mejs-time-current"></span>
<span class="mejs-time-hovered no-hover"></span>
<span class="mejs-time-handle">
<span class="mejs-time-handle-content"></span>
</span>
<span class="mejs-time-float">
<span class="mejs-time-float-current">00:00</span>
<span class="mejs-time-float-corner"></span>
</span>
</span>
</div>
<div class="mejs-time mejs-duration-container">
<span class="mejs-duration">00:00</span>
</div>
</div>
</div>
</div>
I wonder how to express the Audio Block in divs to allow customization? Or is there another way?
