# Heading

The main headline. Its visual size is set independently from the semantic HTML tag, so you can keep correct heading order for SEO while styling freely.

| Setting                                              | Description                                                                                                          |

| Text                                                 | The heading content.                                                                                                 |

| HTML tag                                             | Semantic tag rendered (Paragraph, H1–H6). Use headings in order (H1 → H2 → H3) for SEO. If unsure, choose Paragraph. |
| Text style                                           | Font family: Heading, Body, or Accent (Custom size only).                                                            |
| Font size / Line height / Letter spacing / Text case | Fine typography controls, available when Size is Custom.                                                             |
| Custom for mobile                                    | Separate font size and line height on mobile.                                                                        |
| Highlight style                                      | Emphasize part of the text: color, underline (soft / double / wavy), circle outline, or highlight bar / solid.       |
| Rotation                                             | Slight tilt applied to the highlight.                                                                                |
| Gradient                                             | Gradient fill for the highlight — overrides solid highlight colors.                                                  |
| Highlight text color                                 | Text color inside the highlight.                                                                                     |
| Width                                                | **Fit** (content width), **Fill** (container width), or **Custom** — set independently for desktop and mobile.       |
| Limit width                                          | Cap the block to a **Max width**.                                                                                    |
| Animation                                            | Entrance effect (Fade, Scale, Slide, Rotate words) played on scroll, with an optional **Delay**.                     |
| Padding                                              | Outer spacing: top / bottom, with independent mobile values via **Custom for mobile**.                               |

The **Rotate words** animation cycles through multiple words in place — wrap each word on its own line in the text field.
