In the "Pages" section we can enter each page and see the "Body", which is the visual part of the page.

There we can drag-n-drop visual elements. In this case, we will add an H3 and insert the text. Like this can nest the tags, sections, and insert inside images, texts, and so on. You can see that building the body of content, interactive and dynamic elements, according to our design's interface, is intuitive and easy.
