# Custom Layer Legends

The legend for a layer can be customized to match your custom style, (or the style of your website).

Legends use standard HTML notation. [Quick Intro to HTML](https://developer.mozilla.org/en-US/docs/Learn/HTML/Introduction_to_HTML/Getting_started)

Default Legend Code

Here is an example of the default legend for a point layer colored red:

```
div class="omh-legend">
 <div class="point" style="background-color: red">
 </div>
 <h3>{NAME}</h3>
 </div>
```

In this example we are using the grid design from [http://materializecss.com/grid.html ](http://materializecss.com/grid.html)which is the UI design library used by MapHubs and is automatically available.

```
<div class="omh-legend">
 <h3>{NAME}</h3>
 <style scoped>
     .icon-col {
        width: 24px !important; 
        height: 100%;
     }
 </style>
  <div class="row no-margin" style="height: 14px;">
    <div class="col icon-col s2 no-padding valign-wrapper">
         <div class="col s4 no-padding circle valign" 
            style="background-color: red; width:4px; height: 4px">

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.maphubs.com/advanced/custom-layer-legends.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
