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>

Example

<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:

Example

<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.
