# Visual and logo rules

> Use Chevron, header underline, icon, icon conditional, and logo rules in Grunt

This page covers the legacy rules that turn cell content into more visual slide elements.

## Chevron rule

Use Chevron to show sequence, direction, process steps, or timeline flow.

The legacy support article documents these property groups:

* **Style** for fill and outline
* **Appearance** for skew, direction, and flat starting edge
* **Size**
* **Margin**

Chevron direction can flow:

* Left to right
* Right to left
* Top to bottom
* Bottom to top

## Header, underline rule

Use Header, underline when header cells need a stronger visual separation from the rows below.

The legacy support article highlights:

* **Line style** for color, width, and thickness
* **Label style** for text styling
* **Alignment**
* **Margin**

This rule is useful when a simple underline plus controlled header typography is enough, without turning the header into a full shape.

## Icon rule

Use Icon when every targeted cell should get the same icon.

The legacy support article describes these property groups:

* **Style** for icon choice and color
* **Layout** for placement in or around the cell
* **Size**
* **Margin**

Use Icon when the visual marker is static across the whole target area.

## Icon conditional rule

Use Icon conditional when the icon should depend on the cell value or another value source.

The legacy support article highlights:

* A **Conditions** section with logical operators
* **Layout**
* **Size**
* **Margin**

Useful examples include:

* Status indicators
* Up/down trend arrows
* Category-specific symbols

If you select a range before adding the rule, Grunt can create starter conditions from the selected data automatically.

## Logo rule

Use Logo when company names or other identifiers should be replaced with real logos.

The legacy support article documents two sourcing models:

* Cloud search through Google and Bing
* Local folder sources configured in Grunt settings

Important behaviors:

* Logos can take a few extra seconds to resolve
* You can choose alternative search results
* You can refine the search term when the first result is wrong
* Local sources are preferred based on their order in settings

The same article also notes a privacy tradeoff: cloud logo search shares the search term with the external search providers.

## Choosing between these rules

* Use **Chevron** for process flow
* Use **Header, underline** for structured table headers
* Use **Icon** for static repeated markers
* Use **Icon conditional** for value-driven symbols
* Use **Logo** for company or brand identity
