v-title | Auxiliary text display（like el-tooltip ）

I'm trying to use Material UI to create a reusable navigation tab, however, I am having trouble passing the object over to my functional component and mapping it out. Nothing displays when mapping.

I am fairly new to react hooks. Thanks in advance.

Class Component (passing state over to Navigation)

I have been searching for fixes for hours. I'm quite sure I am not using them correctly. I have tried using wrappers, negative margin, and even a flex-grow fix. I cannot find anything to fix my problem so I am turning to Stack. In desktop width the footer stays at the bottom presumably because the content isn't growing below the footers position. However, when I change the viewport to a smaller mobile size the content grows and it causes the footer to rise.

I am currently in the process of coding my navbar for the mobile viewport. I did some searching and I thought I had a solution, but it turns out the solution isn't working at all. I'm trying to make it so that when the nav burger in the navbar is clicked/ tapped, the navigation options slide in to the screen from right to left. I'm not sure where the logical error is, or why the nav burger being clicked isn't responding to the event.

Here is the HTML corresponding to the nav burger:

I am using a button to control a collapsible sidebar menu. On initial load, the button works fine. After following the link and inspecting the element, I can tell the event listener is not being added and the button stops working until I refresh the page. I am new to rails so I am not sure as to why this is the case. Any help is much appreciated!

HTML:

Answer: I needed to give the other elements time to load. So I added a setTimeout method around the code below.

When I try to add a class or style to streams, the top 4 elements in the list get the change, but the other do not. I don't know if this is a problem to do with the querySelectorAll or CSS.

Also, the class node is added to item, but doesn't add to the stream which leads me to believe that it has to do with querySelectorAll.

This maybe even be the fault of other classes from the site I am making this extention for.

The problem code is below:

I'm studying SCSS and I want to use justify-content: space-between or make space between li without using margin, but it doesn't work and nothing changed on browser. Did I miss something? or Did I do some stupid thing?

React component

I am working with an Angular mat-sidenav. On the left I have a navigation and on the right simple comtent.

The place where we see Navigation should have a seperate background-color like the quickly painted image here. So to be 100% clear: I need the div with class nav-title-container to fill the parents width.

Yet when I try to do this, only the few pixels around the text are colored in. Probably because I am doing it wrong. I am also not that familiar with css (it has been quite some years). What simple stuff am I seeing over my head? I pressume the solution is quite simple yet I cannot find it on my own.

HTML

I have this next issue in which I am having quite a significant problem. First of all, I am trying to integrate three div into my slider and all of them retain a Bootstrap 4 skeleton. The code would be like this and furthermore it is being generated from another Jquery function in which I am inserting info from a Database. Therefore, I am putting this info into one of each card.

Basically, my bootstrap vertical navbar has a margin that stretches from its right side, all the way to the right side of the page.

This is what my Vertical Navbar looks like, with only it on the page, without any other content. However, when I add another element on the page, it pushes it down, as shown in the image below, the black box is being pushed down. Highlighted in red is the margin being created by the navbar.
