Blogger Conditional Tags for different page types

 Conditional template tags in Blogger template allows you to specify a part of your template code on specific types of pages or specific URLs.

One practical application could be to display a widget on specific pages. You can hide sidebar on some pages, apply a meta tag to certain page or whatsoever. Complex Blogger templates make large use of these conditional tags. In this post, I'll show you the possible conditional tags and their example usage.

A conditional template tag in Blogger looks like following

<b:if cond='condition_expression'>
    <!-- content when condition is satisfied -->
</b:if>

How to Use conditional tags

To apply a conditional tag to some content, simply put the content inside the opening <b:if cond…> and the closing </b:if> like:

<b:if cond='data:blog.pageType == "item"'>
    # THIS CONTENT WILL BE EXECUTED IF CONDITION IS TRUE
</b:if>

In the example above, the content will only appear on post pages.

The content can be a div, a section, a style tag or another conditional tag etc.

If you want to specify a alternate content (when the condition is false), you need to insert a <b:else/> tag followed by the content, like this:

<b:if cond='data:blog.pageType == "item"'>
    # THIS CONTENT WILL BE EXECUTED IF CONDITION IS TRUE
    # i.e. if current page is post (item) page
<b:else/>
    # THIS CONTENT WILL BE EXECUTED IF CONDITION IS FALSE
    # i.e. if not post page
</b:if>

The <b:else/> also works like an OR operator as explained above.

Example Applications

• Display widgets on specific pages
• Applying different styling to static pages
• Adding FB meta tags and Twitter Card tags
• Load JS on specific pages
• Optimize Blog Title for SEO
