auto height grow

you can set autoHeight to true so when user type something and text overflow a textarea height component will grow by itself in boundary of --jb-textarea-min-height and --jb-textarea-max-height that you set by css variable

document.querySelector("jb-textarea").autoHeight = true;

the good point of set boundary with css variable is you can set different min or max base on device by CSS media queries.

set custome style

in some cases in your project you need to change defualt style of web-component for example you need zero margin or different border-radius and etc.
