TEXTAREAS WITH AUTO-INCREASING HEIGHT USING CSS

Summary from the TLDR Design newsletter

Textareas are great when it comes to accepting a large amount of text from the user. However, the problem with them is that they have a fixed height, which has a detrimental impact on accessibility and usability. Thankfully, an experimental CSS rule with a form-sizing property is coming that will allow the increase of the height of textareas automatically based on the amount of text the user enters.
