Looking through the available HTML entities, I found a flattened DOWN arrow that uses the code ▾
For example:
However, I could not find a similar flattened UP arrow amongst the defined HTML entities, so I found this CSS technique that will turn a regular unflattened UP arrow ▴
;
into a flattened UP arrow. The trick is to place the HTML entity inside an HTML span element with a CSS class name, then in the CSS for that class name, use these two settings:
transform: scaleX(2); /* Stretch it x 2 on the x axis */ position: absolute;
Here is what the HTML looks like for the skewed entity:
<span class="skewed-up-arrow">▴</span>
Here is the complete example and code on codepen:
