I've been using this method to render multiple custom elements from an array but this is my first time doing it using a map data structure. It compiles fine but renders nothing. I've set up a codesandbox here.

I am trying to create a transition that moves a white div on top of an image. I can do that with ONE image currently, however, I would like to be able to do this with two or more images…

I think the issue has something to do with the position property here, but I am not sure what the actual solution would be.

Here is a codepen: https://codepen.io/jon424/pen/XWzGNLe When you click “toggle”, you will see the transition happen over the first image, but I would like the same thing to happen over the second image at the same time. Any idea how to do this?

In this example, if you select the toggle button, the image will be covered by another div. The white square will gradually cover the image from the top of the image to the bottom.

I simply want to reverse this effect. I want the white square to cover the image, moving from the bottom of the image to the top.

I’ve tried using a negative value for max-height in the .covered class, but that wasn’t working. Any idea on how I can go about doing this?

I have a block which becomes pinned and scrolls horizontally.

Within this block, I have a vector which has a width of 3573px.

When a user scrolls horizontally, I want the vector to scroll also, alongside the images in my demo.

Have tried moving my vector under .horizontalScroller__scroll, so that it scrolls alongside the images, but that didn't work.

See demo:

I have read a similar question's answer here, but it only says about an URL that contains an image file extension (e.g. https://i.imgur.com/ExdKOOz.png) and this method does not work for an URL without any image file extension (e.g. https://picsum.photos/id/128/100/100).

I used the code below to save and show an image when the URL does not contain an extension. But it did not work.

I'm wanting to show a new image in an existing tag. To accomplish this, I'm updating the src attribute via Javascript. However, after changing the src, the screen doesn't change to show the new image loading. Instead, it waits until the new image is fully downloaded, then swaps it in.

In reality, I'm setting the background-image of the tag to the URL of the thumbnail of the image being loaded. The goal being to have a poor quality image in place that gets gradually replaced with the good quality version. However, since the new image doesn't appear while loading, all I get is the old photo sitting there until the new one suddenly appears.

A simplified example is below. To really see the effect, open your DevTools > Network and set throttling to something slow. Click on the image, then wait until it suddenly changes. This is happening in Firefox and Chrome, so I'm guessing it's by design.

Any ideas how to bypass this behaviour?

I'm trying to create a progress bar that shows how much of a certain element the user still has left to view. Here are some details:

• .postProgressBar appears by default under .postHeroImage
• When the user scrolls, I want the .postProgressBar to slowly fill up based on how much of the .spacer element there is left to scroll to.
• When the .postProgressBar hits the bottom of my header, I want it to become fixed to the bottom of the header (and to unfix when .postHeroImage is in view again).

See my current approach:

I'm working on a React project and I'm trying to use this library(https://www.npmjs.com/package/react-image-gallery)

from npm And from the Documentation, they say we must add these instructions to import the CSS

On my page, I can have several identical sliders with different images, each has a preview image and the main image that changes. when you click on the preview image, it has a blue border. This is how it looks
