Greeting | Greeting Text & Greeting Image | REST library

I'm trying to make custom valueboxes in R Shiny. I've discovered how to change the color of the background, but something is making my value boxes stubby and leaving large gaps in between them. I'd like to display 3 on a line ideally, but even with a width of 4, they appear squished. How can I get them to have more of the red with just a small gap of white in between.

Below is a reproducible example as well as a screenshot.

I am currently trying to write some ECS in C++. Inside my ECS (Entity component system), I have a set of entities which all have a set of components. Like a position, rotation, etc..

I'm trying to iterate over a List of objects, for each of the object I want to display a composable card. The problem is that you cant call Composable functions from inside the list.forEach{} brackets.

I've built a small web-app. This is how my home page looks like:

And this is a code that is responsible for handling this:

I have multiple sliders that are reactive upon other data that I want to change the color of. I'm trying to avoid long bouts of CSS code, so I'd like to use shinyWidget's setSliderColor() function is possible. This answer worked when I just had one slider, but now that I have two sliders, it won't work. Here's a reproducible example:

For one time messages, the sender send a message, the receiver receives a response via a callback.
