How do I make a sideways L look in html/css? : <p><a href="https://i.stack.imgur.com/PXZnP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/PXZnP.png" alt="enter image description here"></a></p>

<p>I know the title wasn't the best way to describe it.  But I am trying to recreate the symbols shown in the image on both sides of the word interval.  I have no idea how to do this.  Is it a symbol?  Or some kind of graphic using svg?</p>
