I have a textarea called #input
CSS:
#input
{
font-size: 1rem;
color: white;
border: 0px solid black;
padding-right: 1rem;
margin-right: 1rem;
outline: none;
font-family: inherit;
flex-grow: 1;
background-color: transparent;
color: inherit;
resize: none;
overflow-y: auto;
overflow-x: hidden;
position: relative;
/* height: calc(100% - 0.6rem); */
overflow-wrap: break-word;
word-break: break-word;
min-height: 1em;
max-height: 50vh;
height: var(--expand);
}
After load I call:
computedVariables
(
'--expand',
(value, event, tag) => {
console.log(value)
console.log(event)
console.log(tag)
tag.style.height = 'inherit'
const height = tag.scrollHeight
tag.style.height = ''
return height + 'px'
},
"#input",
['input', 'paste', 'blur', 'reprocess']
)
I would expect the function where the console.logs are to be called on an input event. No resizing happens, no console.logs are triggered.
As we get closer to Houdini implementation, it would be great if this could include an addition for CSS.registerProperty
. Great work on this, love the idea.
