I have searched for a solution that will visualize process steps in my web application. I have found the following excellent write-up by Stephen A Thomas:
Tracking Progress in Pure CSS (Original Link now dead)
In his approach Thomas even gets away with just using CSS - no Javascript! In an essence the following CSS code from his article does the trick for me:
<style>
<!-- Progress with steps -->
ol.progtrckr {
margin: 0;
padding: 0;
list-style-type: none;
}
ol.progtrckr li {
display: inline-block;
text-align: center;
line-height: 3em;
}
ol.progtrckr[data-progtrckr-steps="2"] li { width: 49%; }
ol.progtrckr[data-progtrckr-steps="3"] li { width: 33%; }
ol.progtrckr[data-progtrckr-steps="4"] li { width: 24%; }
ol.progtrckr[data-progtrckr-steps="5"] li { width: 19%; }
ol.progtrckr[data-progtrckr-steps="6"] li { width: 16%; }
ol.progtrckr[data-progtrckr-steps="7"] li { width: 14%; }
ol.progtrckr[data-progtrckr-steps="8"] li { width: 12%; }
ol.progtrckr[data-progtrckr-steps="9"] li { width: 11%; }
ol.progtrckr li.progtrckr-done {
color: black;
border-bottom: 4px solid yellowgreen;
}
ol.progtrckr li.progtrckr-todo {
color: silver;
border-bottom: 4px solid silver;
}
ol.progtrckr li:after {
content: "\00a0\00a0";
}
ol.progtrckr li:before {
position: relative;
bottom: -2.5em;
float: left;
left: 50%;
line-height: 1em;
}
ol.progtrckr li.progtrckr-done:before {
content: "\2713";
color: white;
background-color: yellowgreen;
height: 1.2em;
width: 1.2em;
line-height: 1.2em;
border: none;
border-radius: 1.2em;
}
ol.progtrckr li.progtrckr-todo:before {
content: "\039F";
color: silver;
background-color: white;
font-size: 1.5em;
bottom: -1.6em;
}
</style>
As well as HTML tags from his example (I use Grails GSP pages to generate tags and 'done/todo' class dynamically):
<ol class="progtrckr" data-progtrckr-steps="5">
<li class="progtrckr-done">Order Processing</li>
<li class="progtrckr-done">Pre-Production</li>
<li class="progtrckr-done">In Production</li>
<li class="progtrckr-done">Shipped</li>
<li class="progtrckr-todo">Delivered</li>
</ol>
Hope it helps. Works pretty well for me.
UPDATE: The following (shortened) version also works well.
ol.progtrckr {
display: table;
list-style-type: none;
margin: 0;
padding: 0;
table-layout: fixed;
width: 100%;
}
ol.progtrckr li {
display: table-cell;
text-align: center;
line-height: 3em;
}
... and the rest of the CSS ...
<ol class="progtrckr">
...
</ol>
display: table; table-layout: fixed; width: 100%
ensure that the list items are automatically sized equally as long as the content does not overflow. There is no need to use data-progtrckr-steps
and its associated CSS.
