I'm trying to recreate this background image

I have tried using clip-art on this image but I'm not able to get that shape.

I am working on an HTML site and I am using the bootstrap 5 frameworks.

MY GOAL is to add bootstrap 5 Carousel in my section next to an image, like show in this image.

I have directly copied Carousel code from bootstrap docs here is the link

https://getbootstrap.com/docs/5.1/components/carousel/#slides-only

But for some reason, the Carousel is not showing any content it is only showing controls and slider buttons like this

what m i doing wrong?

Desired outcome: I have three columns. I need them to be all the same width, as well as text and buttons to be on the same level in all three of them.

Problem: Depending on the number of words, columns become wider and buttons start to jump when text is resizing, and all three texts are resizing on a different points. I need to prevent that. How can I achieve this?

HTML:

So I'm trying to make this button animation while learning about pseudo-elements and I'm really close to achieving what I want but there's something that really bugs me.

This is what I have currently: https://codepen.io/saifeldeenadel/pen/xxPwvdj?editors=1100

I want to underline my element finitely while keeping it in center of the page using text-align: center. However, using border-bottom(for underline) and text-align: center at the same time, the underline goes on till the end of the page. Is there any other way I can achieve this? Hope you understand my issue. Thanks in advance.

I'm stuck at the dropdown menus. Not sure how to lay it out 2 columns 3 rows

Forgot to mention, I want to make it single column when I shrink browser, like when we're viewing it on phones. I'd like it to look like this - https://imgur.com/a/zmn3DZo

I'm not sure how I'm suposed neatly line inputs in a row. I tried using flex and position: relative (for the label) but that didn't work for me. I'm trying to make it look like this for example for both my checkboxes and radios:

But this is what I got instead:

Please explain how I can find a solution to this problem.

I´m trying to plot a heart beat for 24 hours, I have data for every second. The problem I´m running through is that when I plot the data and assign to each beat the "intensity zone", I get a straight line in the graph (check the blue line between 4:00 and 10:00) instead of just the color for that data. Also, I´m getting a line for NA values, and although I have added na.rm=TRUE it still shows in the graph.

Here's the code and the data:
