There is no attribute "excerpt" – Help to solve this validation error

There is no excerpt attribute. I think you have it confused with the title attribute.

<h2>
    <a style="font-size:12px" href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a>
</h2>

Thank you,
Your code isn’t ok for me beacause make to disappear my post excerpt, when you are with the mouse over the photos – https://www.liviufratila.ro/

simply remove it;

example:

<h2><a style="font-size:12px" href="<?php the_permalink(); ?>"><?php the_excerpt(); ?></a></h2>

alchymyth Thank you! It worked!

Now, in this new line that solve the topic problem, I have a secondary and last error:

“document type does not allow element “p” here; missing one of “button”, “map”, “object”, “ins”, “del”, “noscript” start-tag” (W3C Validator)

But I don’t see “p” in php code…

<h2><a style="font-size:12px" href="<?php the_permalink(); ?>"><?php the_excerpt(); ?></a></h2>

the_excerpt() automatically wraps the text into a <p> tag;

try and use this instead:

<h2><a style="font-size:12px" href="<?php the_permalink(); ?>"><?php echo get_the_excerpt(); ?></a></h2>

Thank you again! You help me a lot to validate the html.
