[Resolved] Wrong title tag

Hi,
I’m using a list showing the next 3 months injected after the 1st paragraph of each post/page. I found that the titles are <h2>. I had set in “content” the title element to <h4>, now changed to <p>, but no change.
I’m limiting the title lenght to 3 lines with the code

<style>
	.wp-show-posts-entry-title {
    line-height: 1.2em;
		min-height: 3.6em;
    max-height: 3.6em;
		overflow: hidden;
}
</style>
