[icons] Add tooltip to font awesome icon

Has anyone here added tooltips to font-awesome icons?

I have the following jsfiddle, but cannot seem to find a guide to add tooltips to the icons.

<header>
  <!-- icons for settings, change pwd and list of active sessions -->
  <div id="menuIcons">
    <i class="fa fa-cog"></i>
    <i class="fa fa-user"></i>
    <i class="fa fa-lock"></i>
  </div>

  <!-- display welcome text -->
  <div id="welcomeText">
    <p>Welcome Harriet</p>
  </div>

</header>

In regards to this question, this can be easily achieved using a few lines of SASS;

HTML:

<a href="https://www.urbandictionary.com/define.php?term=techninja" data-tool-tip="What's a tech ninja?" target="_blank"><i class="fas fa-2x fa-user-ninja" id="tech--ninja"></i></a>

CSS output would be:

a[data-tool-tip]{
    position: relative;
    text-decoration: none;
    color: rgba(255,255,255,0.75);
}

a[data-tool-tip]::after{
    content: attr(data-tool-tip);
    display: block;
    position: absolute;
    background-color: dimgrey;
    padding: 1em 3em;
    color: white;
    border-radius: 5px;
    font-size: .5em;
    bottom: 0;
    left: -180%;
    white-space: nowrap;
    transform: scale(0);
    transition: 
    transform ease-out 150ms,
    bottom ease-out 150ms;
}

a[data-tool-tip]:hover::after{
    transform: scale(1);
    bottom: 200%;
}

Basically the attribute selector [data-tool-tip] selects the content of whatever's inside and allows you to animate it however you want.

codepen Is perhaps a helpful example.

<div class="social-icons">
  <a class="social-icon social-icon--codepen">
    <i class="fa fa-codepen"></i>
    <div class="tooltip">Codepen</div>
</div>

body {  
  display: flex;
  align-items: center;
  justify-content: center;
  min-height: 100vh;
}

/* Color Variables */
$color-codepen: #000;

/* Social Icon Mixin */
@mixin social-icon($color) {
  background: $color;
  background: linear-gradient(tint($color, 5%), shade($color, 5%));
  border-bottom: 1px solid shade($color, 20%);
  color: tint($color, 50%);

  &:hover {
    color: tint($color, 80%);
    text-shadow: 0px 1px 0px shade($color, 20%);
  }

  .tooltip {
    background: $color;
    background: linear-gradient(tint($color, 15%), $color);
    color: tint($color, 80%);

    &:after {
      border-top-color: $color;
    }
  }
}

/* Social Icons */
.social-icons {
  display: flex;
}

.social-icon {
  display: flex;
  align-items: center;
  justify-content: center;
  position: relative;
  width: 80px;
  height: 80px;
  margin: 0 0.5rem;
  border-radius: 50%;
  cursor: pointer;
  font-family: "Helvetica Neue", "Helvetica", "Arial", sans-serif;
  font-size: 2.5rem;
  text-decoration: none;
  text-shadow: 0 1px 0 rgba(0,0,0,0.2);
  transition: all 0.15s ease;

  &:hover {
    color: #fff;

    .tooltip {
      visibility: visible;
      opacity: 1;
      transform: translate(-50%, -150%);
    }
  }

  &:active {
    box-shadow: 0px 1px 3px rgba(0, 0, 0, 0.5) inset;
  }

  &--codepen { @include social-icon($color-codepen); }

  i {
    position: relative;
    top: 1px;
  }
}

/* Tooltips */
.tooltip {
  display: block;
  position: absolute;
  top: 0;
  left: 50%;
  padding: 0.8rem 1rem;
  border-radius: 3px;
  font-size: 0.8rem;
  font-weight: bold;
  opacity: 0;
  pointer-events: none;
  text-transform: uppercase;
  transform: translate(-50%, -100%);
  transition: all 0.3s ease;
  z-index: 1;

  &:after {
    display: block;
    position: absolute;
    bottom: 0;
    left: 50%;
    width: 0;
    height: 0;
    content: "";
    border: solid;
    border-width: 10px 10px 0 10px;
    border-color: transparent;
    transform: translate(-50%, 100%);
  }
}

You should use 'title' attribute along with 'data-toogle' (bootstrap).

For example

<i class="fa fa-info" data-toggle="tooltip" title="Hooray!"></i>Hover over me

and do not forget to add the javascript to display the tooltip

<script>
    $(document).ready(function(){
        $('[data-toggle="tooltip"]').tooltip();   
    });
</script>

The simplest solution I have found is to wrap your Font Awesome Icon in an <a></a> tag:

   <Tooltip title="Node.js" >
     <a>
        <FontAwesomeIcon icon={faNode} size="2x" />
     </a>
   </Tooltip>

Simply use title in tag like

<i class="fa fa-edit" title="Edit Mode"></i>

This will show 'Edit Mode' when hover that icon.

Simply with native html & css :

<div class="tooltip">Hover over me
  <span class="tooltiptext">Tooltip text</span>
</div>

/* Tooltip container */
.tooltip {
  position: relative;
  display: inline-block;
  border-bottom: 1px dotted black; /* If you want dots under the hoverable text */
}

/* Tooltip text */
.tooltip .tooltiptext {
  visibility: hidden;
  width: 120px;
  background-color: #555;
  color: #fff;
  text-align: center;
  padding: 5px 0;
  border-radius: 6px;

  /* Position the tooltip text */
  position: absolute;
  z-index: 1;
  bottom: 125%;
  left: 50%;
  margin-left: -60px;

  /* Fade in tooltip */
  opacity: 0;
  transition: opacity 0.3s;
}

/* Tooltip arrow */
.tooltip .tooltiptext::after {
  content: "";
  position: absolute;
  top: 100%;
  left: 50%;
  margin-left: -5px;
  border-width: 5px;
  border-style: solid;
  border-color: #555 transparent transparent transparent;
}

/* Show the tooltip text when you mouse over the tooltip container */
.tooltip:hover .tooltiptext {
  visibility: visible;
  opacity: 1;
}
