Getting Rid of Bullet Points from <Ul>

Remove bullet points in UL in CSS

#menu-bar ul will only target the ul which is a direct child of #menu-bar, the style wont propagate to nested ul's within.

To target the nested ul you can either target it directly by it's class:

.noJS {
    list-style:outside none none;
}

or by drilling into the nested structure:

#menu-bar ul li ul {
    list-style:outside none none;
}

I need an unordered list without any bullets

You can remove bullets by setting the list-style-type to none on the CSS for the parent element (typically a <ul>), for example:

ul {
  list-style-type: none;
}

You might also want to add padding: 0 and margin: 0 to that if you want to remove indentation as well.

See Listutorial for a great walkthrough of list formatting techniques.

How can I remove bullets from html list without losing other formatting?

As Thomas L. mentioned in the comments, you can add a CSS style component to your code to hide the bullet points that are being created for the li tags.

So in each of your li tags you would change them like so:

<li style="list-style: none">

Here is your modified code:

.link-container {
    background-color: #4e4e4e91;
    border-color:rgba(129, 191, 235, 0.978);
    border-width: 1px;
    border-style: solid;
    height: 50%;
    border: 2px solid rgba(129, 191, 235, 0.978) ;
    border-radius: 30px;

    }

        .links {
            display: flex;
            justify-content: space-between;
            align-items: center;
            margin-left: 100px;
            margin-right: 100px;
        }

        a {
            color: rgb(245, 245, 245);
            text-decoration: none;
            font-weight: bold; 
            border: 1px solid ;
            background: 0;
            font-weight: 600;
            border-radius: 40px;
          
    
    padding: 0 10px;   
        }
        
        a:hover{
            
            color: rgb(129, 191, 235)
            
            
        }

        .input-box {
            background-color: white;
            color: gb(129, 191, 235);
        }

<div>
    <div class= "link-container">
      <h6 class="links">

Remove bullets from <ul>?

#menu ul is trying to target a ul that is a descendant of #menu. This is incorrect, since in your case they are the same element. ul#menu would be correct.

Removing bullets from unordered list <ul>

ul.menu li a:before, ul.menu li .item:before, ul.menu li .separator:before {
  content: "\2022";
  font-family: FontAwesome;
  margin-right: 10px;
  display: inline;
  vertical-align: middle;
  font-size: 1.6em;
  font-weight: normal;
}

Is present in your site's CSS, looks like it's coming from a compiled CSS file from within your application. Perhaps from a plugin. Changing the name of the "menu" class you are using should resolve the issue.

Removing black dots from li and ul

Relatable post

Those black dots you are referencing to are called bullets.

They are pretty simple to remove, just add this line to your css:

ul {
    list-style-type: none;
}
