Use of Conditional Tags
For the use of the latest version of the conditional tag above, you can easily use it in HTML or widgets in the blogger theme. Examples like this below:
<b:if cond='data:view.isMobile'>
// html or widget here
</b:if>
To hide a page from certain conditional tags, put "exclamation mark" or "not" before data:view
<b:if cond='!data:view.isMobile'>
// html or widget here
</b:if>
Or
<b:if cond='not data:view.isMobile'>
// html or widget here
</b:if>
Thanks! So much from Droidnur, thank you, and best of luck.
