I wrapper textarea in a component Wrapper.js which will dynamically add html element around the children.

However, the children(textarea) loses it's focus as the wrapper re-renders? How to fix this issue?

• autoFocus={true} won't work. it will set the cursor to the first character in the input.

I am trying to use the intersection observer API to conditionally display items in a CSS grid when the user starts scrolling, but it seems to go into an infinite rendering loop. Here is my code.

Here is the link to my live code on StackBlitz

Also what I'm trying to achieve is not render too many items on the screen when I can avoid it. I'm not sure if display: none actually makes the browser work less. If this is not the correct way, please let me know.

Thanks for reading my question. Any help is highly appreciated.

I created a new react-ts app using yarn create @vitejs/app my-app --template react-ts.

I installed tailwind using yarn add --dev tailwindcss@latest postcss@latest autoprefixer@latest.

I initialized tailwind: npx tailwindcss init -p.

I set from and to in postcss.config.js:

I am trying to change the position of my slip element via animation transition whenever a user scrolls to the bottom of the page. The problem that I'm having is that I don't know how to switch the positioning from flex to relative. The slip element needs to be positioned above the footer.

I've managed to achieve this with only switching classes but I don't like the jerking animation so I wanted to add some transition but now I don't know how to make it stick above the footer.

How do I make the slip element stick on top of the footer and not be fixed when a user scrolls to the bottom of the page? The goal is to achieve this with a smooth transition/animation.

Here is my stackblitz example of the problem.

I have StackBlitz Demo here

Simple question is it possible to show the first item in a map based on a conditional.

So in my example how could I just output the first item '1' if 'first' is true

I'm working on a React form. The web component part works fine, but as shown in the example, I'm having issues updating properties in the App component, when attributes are updated async later.

code example: https://stackblitz.com/edit/react-ts-nypnbz?file=index.tsx

What am I missing to get the token value sent to when its updated async as demonstrated by the setTimeout on the host page?

There are few questions very similar to this but I couldn't find my answer. I want to give style to a styled component which is inside of a normal react component without using extra wrapper.

I have a problem understanding why in some cases componentWillUnmount method is not called even if the component I would expect is unmounted.

To be more concrete, this is the example. Let's consider a Parent component with a button and 2 children: Child_Odd and Child_Even. Child_Odd is "shown" if the number of clicks of the button is odd, otherwise Child_Even is "shown".

I would expect to see the the componentWillUnmount method to be called when the component "disappears", but on the contrary this does not happen. Here a stackblitz reproducing the case (this stackblitz includes also a similar case where the componentWillUnmount method is actually called).

This is the relevant code

I'm trying to achieve the following layout without using absolute positioning

The reason is that I would like to use css grid or flexbox as much as possible and try to avoid taking thins out of the flow if at all possible. In this case the surrounding div has a padding which should be respected, if it comes to that, and instead it should increase it's height if necessary. Usually I use max-content with css grid to achieve this.

If it was only the text it would have been as easy as align-items: center; however, because of the images/badges, the text will not properly align in the center if I do this.
