I need to include a complex historical timeline into about page (I use the Palo Alto theme). I have created a new page template with HTML code only, then created a new page based on this template and added a CSS code to the theme.css file. In preview. The page looks fine. However, I need to include this HTML timeline into a standard page that offers several sections, product feature, rich text, and text with image.
I tried to insert the HTML code directly to the page editor, however, the custom HTML always appears at the bottom, just above the footer. I need it to appear between standard sections.
