Tri-state icon convention?

I have to design a report with validations about data introduced. In some fields I have a typical triple state. Let me give an example:

Documents

  • A good file added -> ✓
  • A bad file added -> x
  • It doesn’t require file -> ?????

That third state “don’t required” … have some standardized icon or similar? I don’t see any good examples in web and I can’t think something recognizable.

Edit: The file which is not required needs an icon because is the final step of the validation and the user can’t upload anything after the report is created

What is the best location on a form for an information icon?

I am trying to create a form for my web app, which requires information elements to be added. In general I would refer to the documentation of the framework that I would be using (which in my case would be Bootstrap if this would be any helpful information).

Whenever reading through the documentation, I cannot seem to find any information regarding my need for given element. (The only thing that might be useful is that I could be using an icon from the Bootstrap framework called: glyphicon-info-sign).

I could be using something similar the answer given on this question I found on SE.

Option 1:

Option 1 form

Option 2:

Option 2 form

Option 3:

Option 3 form

What is considered best practice or what might be the best solution concerning the placement location of an information icon? Should I place the icon directly after the label, should I make sure there is enough space between the label and the icon? Should the icon be after an input field?

How to remove duplicate icon on dock?

after using jar xvf <filename> command to unzip a file I suddenly got a second duplicate of the files icon on my dock as you can see on the picture below.

https://ibb.co/fFyBQvc

Clicking the “duplicate” icon at the bottom opens a new files window as normal but only accessible by the “real” icon as you can see from the dots aside the “real” icon. I do not have an option to remove the duplicate icon from the favorites but I do have “add to favorites” option which is quite strange. To give you more details, these duplicate icons do not appear on the dash if I search for “files”.

Thanks in advance for any help to get rid of this duplicate icon.

Checkbox con apariencia de boton con CSS + icon

Estoy creando un checkbox que tenga apariencia de un boton con CSS. Está cogiendo bien las clases la label pero tengo un icono dentro de la label que no me cambia el color cuando el input esta checked. Alguna idea de cómo cambiar el color del icono?

<div class="checkBtn">  <input id="checkCarrito" type="checkbox">  <label for="checkCarrito"><i class="icon-carrito"</i></label> </div>  .checkBtn label{   display: flex;   max-width: 150px;   min-width: 150px;   height: 150px;    justify-content: center;   align-items: center;   cursor: pointer;   background-color: #f8f8f8;   color: #82838c;   margin: 0.5%;   border-radius: 5px;   font-size: 3em; }  .checkBtn label:hover {       background: #dbdcde; }  .checkBtn input[type=checkbox]:checked + label{   background-color: #17a2b8;       color: #fff !important;  }  .checkBtn input[type=checkbox]:checked + label +i{   background-color: #17a2b8;       color: #fff !important;  } .checkBtn input[type=checkbox] {     visibility: hidden; } 

El icono se encuentra en otro fichero .css en una carpeta con las fuentes de los iconos.

.icon-carrito:before {     content: "\e903";     color: #8b8b8b; }
