Creating Reusable and Scalable Calendar Icon in HTML5 and CSS3

This article explains how tro create a calendar icon for your blog or website, and yes, it is scalable, so you can resize it to any ratio and it will not be blurred just by changing a font-size. 

You’re free to change the color/size of the text or an icon or anything as you prefer. I’m going to show you how:

Figure 1: Template Div

The following is the template that I will be modifying to get the desired output. It contains a main wrapper Div and three elements inside for Day, Month and Date respectively. I had the option to put all the three in a span but just to reduce the complexity of the CSS I put them in separate tags.

And here’s the style for this icon wrapper, you can change the size of the icon in just one go by changing the wrapper’s font-size attribute.

Figure 2: Icon Wrapper style


Here’s the complete HTML and CSS:




Reusable Calendar Icon

body
 {
  font-family: “Segoe UI”, Frutiger, “Frutiger Linotype”, “Dejavu Sans”, 
  “Helvetica Neue”, Arial, sans-serif;
  font-size: 100%;

  margin: 10px
  color: #333;
  background-color: #cecece;
 }
  div.calendarDate{
  font-size:1em; /*change calendarIcon size */
  display: block;
  position: relative;
  width: 7em;
  height: 7em;
  background-color: #fff; 
  border-radius: 0.7em;
  -moz-border-radius: 0.7em; 
  box-shadow: 0 1px 0 #bdbdbd, 0 2px 0 #fff, 0 3px 0 #bdbdbd,
  0 4px 0 #fff, 0 5px 0 #bdbdbd, 0 0 0 1px #bdbdbd;
  overflow: hidden;
  }
 div.calendarDate *
 {

  width: 100%;
  font-size: 1em;
  font-weight: bold;
  font-style: normal;
  text-align: center;
 }
div.calendarDate strong
 {

Template Tag in HTML5

W3C has introduced a new “template” tag that provides a mechanism to define HTML markup fragments as prototypes. In practice, a template can be used to insert fragments of HTML code into your page, for example:
<template id=”rowTemplate”>
<tr>
<td class=”record”></td>
<td></td>
<td></td>
</tr>
</template>
Features
The following are the features of the template tag:
  • The template code can be defined nearly anywhere; the head, body or even a frameset.
  • Templates will not be displayed
  • Templates are not considered to be part of the document, in other words using document.getElementById(“mytablerow”) will not return child nodes.
  • Templates are inactive until used, in other words enclosed images will not download, media will not play, scripts will not run, and so on.
Using templates
To use a template, it must be cloned and inserted into the DOM. For example, assuming the following HTML:
<table id=”testTable”>
    <thead>
        <tr>
            <td>
                ID
            </td>
            <td>
                name
            </td>
            <td>
                twitter
            </td>
        </tr>
    </thead>
    <tbody>
        
    </tbody>
</table>
<template id=”rowTemplate”>
<tr>
<td class=”record”></td>
<td></td>
<td></td>
</tr>
</template>

Use the following to clone the new row and append it to the table in JavaScript:

// get tbody and row template
var t = document.querySelector(“#testTable tbody”),
row = document.getElementById(“rowTemplate”);
// modify row data
var td = row.getElementsByTagName(“td”);
td[0].textContent = “1”;
td[1].textContent = “Sunny”;
td[2].textContent = “@sunny_delhi”;
// clone row and insert into table
t.appendChild(row.content.cloneNode(true));

Q: Can we use templates?
A: Not yet. For now, it’s supported in the latest version of Chrome and Firefox nightly builds but yes, there’s a shim demonstrated that you can use as a workaround until it is implemented by all prominent browsers. It probably works in IE also.

Separation of HTML code and JavaScript is a good idea!
