How do I make this CSS appear in every blog tag, but I don't want it to appear in specific tags
This code does the opposite, it specifies which tag should appear in the css, I would like a code that could show the css everywhere except in certain tags
<b:if cond='data:blog.searchLabel in ["car", "Identity", "Brand"]'>
<style>
body { background: #e2ad44 }
</style>
</b:if>
Use the logical operator not to reverse condition:
<b:if cond='data:blog.searchLabel not in ["car", "Identity", "Brand"]'>
<style>
body { background: #e2ad44 }
</style>
</b:if>
