How to implement progress tracking bar using css? (code example)

This article shares with you how to use css to implement a progress tracking bar? (Code sample), friends in need can refer to it.

This is a small tutorial on how to create a very simple UI widget to tell the user which step of the process they are at.

We will start with a small snippet of HTML:

<ol class="track-progress">
  <li>
    Site Information 
    </li>
  <li>
    Data Source  
    </li>
  <li>
    Final Details  
    </li>
    </ol>

Now, we will reset the ordered list style and make the list elements appear on a single line. We use the following CSS code:

.track-progress {
  margin: 0;
  padding: 0;
  overflow: hidden;
  }
.track-progress li {
  list-style-type: none;
  display: inline-block;
  position: relative;
  margin: 0;
  padding: 0;
  text-align: center;
  line-height: 30px;
  height: 30px;
  background-color: #f0f0f0;
  }

You will get the following effect:

Make this tracker take up all available width. For flexibility, we'll add an HTML attribute to the tracker

tag to declare the number of steps in the process. This way we can add some default width by changing the property value.

HTML:


<ol class="track-progress" data-steps="3">
  <li>
    Site Information  
    </li>
  <li>
    Data Source  
    </li>
  <li>
    Final Details  
   </li>
</ol>

CSS:

.track-progress[data-steps="3"] li { width: 33%; }
.track-progress[data-steps="4"] li { width: 25%; }
.track-progress[data-steps="5"] li { width: 20%; }

becomes the following effect:




To remove this annoying white space, we must delete the white space between the

1. tags. We can do this with HTML comments:

    <ol class="track-progress" data-steps="3">
      <li>
        Site Information   </li><!--
   --><li>
        Data Source   </li><!--
   --><li>
        Final Details   </li>
    </ol>

   The effect is as follows:
   

   

   I want to add some kind of arrow to indicate the steps in the sequence The actual direction, so I needed additional markup to isolate the step content from other decoration materials:

    <ol class="track-progress" data-steps="3">
      <li class="done">
        <span>Site Information</span>
      </li><!--
   --><li class="done">
        <span>Data Source</span>
      </li><!--
   --><li>
        <span>Final Details</span>
      </li>
    </ol>

   I added a completed class to represent the different styles of progress. Here is the CSS:

   .track-progress li > span {
     display: block;
     color: #999;
     font-weight: bold;
     text-transform: uppercase;
     }
   .track-progress li.done > span {
     color: #666;
     background-color: #ccc;
     }

   The result is:
   

   

   To add the arrow we will use the :before and :after pseudo-elements as well as giving the border a huge Tips for sizing to create corners:

   .track-progress li > span:after,.track-progress li > span:before {
     content: "";
     display: block;
     width: 0px;
     height: 0px;
     position: absolute;
     top: 0;
     left: 0;
     border: solid transparent;
     border-left-color: #f0f0f0;
     border-width: 15px;
     }
   .track-progress li > span:after {
     top: -5px;
     z-index: 1;
     border-left-color: white;
     border-width: 20px;
     }
   .track-progress li > span:before {
     z-index: 2;
     }

   The effect is as follows:

   

   Now we correctly apply the style so that the arrow color matches the state from the previous step, and remove Arrows in the first element:

   .track-progress li.done + li > span:before {
     border-left-color: #ccc;
   }
   .track-progress li:first-child > span:after,.track-progress li:first-child > span:before {
     display: none;
     }

   will look like this:

   

   Now we are going to add an arrow appearance at the beginning and end of the tracker so that we can add More tags:

   <ol class="track-progress" data-steps="3">
      <li class="done">
        <span>Site Information</span>
        <i></i>
      </li><!--
   --><li class="done">
        <span>Data Source</span>
      </li><!--
   --><li>
        <span>Final Details</span>
        <i></i>
      </li>
    </ol>

   .track-progress li:first-child i,.track-progress li:last-child i {
     display: block;
     height: 0;
     width: 0;
   
     position: absolute;
     top: 0;
     left: 0;
   
     border: solid transparent;
     border-left-color: white;
     border-width: 15px;}.track-progress li:last-child i {
     left: auto;
     right: -15px;
   
     border-left-color: transparent;
     border-top-color: white;
     border-bottom-color: white;}

   The final effect is as follows:
