First of all apologies for the late response.
I use the plugin The Grid (from Codecanyon) to place posts with featured images in a certain layout on a page.
In the section below the image where information can be included, there is a section available for the summary (the excerpt) of the post. HTML code that I include in there is not executed (except for the <br> element)
