我已经读过几件关于它的事情,但我找不到我需要的东西.我想保留灰色箭头,但我想从默认样式中删除水平条并具有白色背景.你知道我怎么做吗?
这是我现在拥有的(默认微调器样式):

这就是我想要的:

I'm using Firefox and I have this HTML code:
<div contenteditable="true">
This is an empty tag : <b></b> and this is this is <b>not</b>
</div>
Run Code Online (Sandbox Code Playgroud)
When I try to delete a character by pressing the "SUPPR" or "BACKSPACE" key, it removes the <b></b> for no reason.
It works on Chrome.
