Tabs can be really useful especially for content-crowded web sites. You can save plenty of space just by placing your block of content in tabs and displaying one block at a time in the same place.
The content that you break-up in tabs, though, should be somehow relevant. For example, you can separate in tabs content about Weather Forecasting; tabs could be cities in your country, or forecast days.
If you are in the web hosting business, you might want to "tabularize" the different type of web hosting plans you offer, like Shared Web Hosting, VPS Hosting, Cloud Hosting, Dedicated Servers etc.
However, grouping content in tabs can be a “double-edged sword”. As the content is being compact in one tab, other tabs’ content is hidden. If, for example, you are running an e-commerce website that offers technology products like laptops, groupin the various laptop models will forbid potential customers from comparing the laptop features!
Now that we have discussed the importance and value of tabs in a website, lets proceed to the technical side of things: How to create tabs using HTML and CSS. The following example is for a horizontal tab area. We will create the tabs without any images; pure css and html and a small bit of javascript.
In the css file create the following classes:
That’s all you need to do in the css file. Let’s go to the HTML file now.
Wherever you want to place your horizontal tabs, place the following code:
<div id=”Tabs”>
<ul>
<li id=”li_tab1″ onclick=”tab(‘tab1′)” ><a>Tab 1</a></li>
<li id=”li_tab2″ onclick=”tab(‘tab2′)”><a>Tab 2</a></li>
</ul>
<div id=”Content_Area”>
<div id=”tab1″>
<p>This is the text for tab 1</p>
</div>
<div id=”tab2″ style=”display: none;”> <!– We set its display as none because we don’t want to make this
tab visible by default. The only visible/active tab should be Tab 1 until the visitor clicks on Tab 2. –>
<p>This is the text for tab 2.</p>
</div>
</div> <!– End of Content_Area Div –>
</div> <!– End of Tabs Div –>
At the end of your HTML file place the following javascript code. It is necessary for the tabs switching:

Wherever you want to place your horizontal tabs, place the following code:
<div id=”Tabs”>
<ul>
<li id=”li_tab1″ onclick=”tab(‘tab1′)” ><a>Tab 1</a></li>
<li id=”li_tab2″ onclick=”tab(‘tab2′)”><a>Tab 2</a></li>
</ul>
<div id=”Content_Area”>
<div id=”tab1″>
<p>This is the text for tab 1</p>
</div>
<div id=”tab2″ style=”display: none;”> <!– We set its display as none because we don’t want to make this
tab visible by default. The only visible/active tab should be Tab 1 until the visitor clicks on Tab 2. –>
<p>This is the text for tab 2.</p>
</div>
</div> <!– End of Content_Area Div –>
</div> <!– End of Tabs Div –>
At the end of your HTML file place the following javascript code. It is necessary for the tabs switching:
Code:
<script type=”text/javascript”>
function tab(tab) {
document.getElementById(‘tab1′).style.display = ‘none’;
document.getElementById(‘tab2′).style.display = ‘none’;
document.getElementById(‘li_tab1′).setAttribute(“class”, “”);
document.getElementById(‘li_tab2′).setAttribute(“class”, “”);
document.getElementById(tab).style.display = ‘block’;
document.getElementById(‘li_’+tab).setAttribute(“class”, “active”);
}
</script>
