This example shows how to customize markers in the following ways:
add title text, scale the marker, change the background color, change the
border color, change the glyph color, hide the glyph.

### TypeScript

```typescript
const mapElement = document.querySelector('gmp-map')!;

async function init() {
    // Request needed libraries.
    const [{ AdvancedMarkerElement, PinElement }] = await Promise.all([
        google.maps.importLibrary('marker'),
        google.maps.importLibrary('maps'),
    ]);

    // Each PinElement is paired with a marker to demonstrate setting each parameter.

    // Default marker with title text (no PinElement).
    const markerWithText = new AdvancedMarkerElement({
        position: { lat: 37.419, lng: -122.03 },
        title: 'Title text for the marker at lat: 37.419, lng: -122.03',
    });
    mapElement.append(markerWithText);

    // Adjust the scale.
    const pinScaled = new PinElement({
        scale: 1.5,
    });
    const markerScaled = new AdvancedMarkerElement({
        position: { lat: 37.419, lng: -122.02 },
    });
    markerScaled.append(pinScaled);
    mapElement.append(markerScaled);

    // Change the background color.
    const pinBackground = new PinElement({
        background: '#FBBC04',
    });
    const markerBackground = new AdvancedMarkerElement({
        position: { lat: 37.419, lng: -122.01 },
    });
    markerBackground.append(pinBackground);
    mapElement.append(markerBackground);

    // Change the border color.
    const pinBorder = new PinElement({
        borderColor: '#137333',
    });
    const markerBorder = new AdvancedMarkerElement({
        position: { lat: 37.415, lng: -122.035 },
    });
    markerBorder.append(pinBorder);
    mapElement.append(markerBorder);

    // Change the glyph color.
    const pinGlyph = new PinElement({
        glyphColor: 'white',
    });
    const markerGlyph = new AdvancedMarkerElement({
        position: { lat: 37.415, lng: -122.025 },
    });
    markerGlyph.append(pinGlyph);
    mapElement.append(markerGlyph);

    const pinTextGlyph = new PinElement({
        glyphText: 'T',
        glyphColor: 'white',
    });
    const markerGlyphText = new AdvancedMarkerElement({
        position: { lat: 37.415, lng: -122.015 },
    });
    markerGlyphText.append(pinTextGlyph);
    mapElement.append(markerGlyphText);

    // Hide the glyph.
    const pinNoGlyph = new PinElement({
        glyphText: '',
    });
    const markerNoGlyph = new AdvancedMarkerElement({
        position: { lat: 37.415, lng: -122.005 },
    });
    markerNoGlyph.append(pinNoGlyph);
    mapElement.append(markerNoGlyph);
}

![The parts of an Advanced Marker.](https://developers.google.com/static/maps/documentation/javascript/advanced-markers/images/marker_parts.png) **Figure 1**: The parts of an Advanced Marker.

Advanced markers uses two classes to define markers: the
`AdvancedMarkerElement` class provides the basic parameters (`position`,
`title`, and `map`), and the `PinElement` class contains options for further
customization.

In order to add markers to a map, you must first
[load the `marker` library](https://developers.google.com/maps/documentation/javascript/advanced-markers/add-marker.md.txt#load_the_advanced_marker_library)
which provides the [`AdvancedMarkerElement`](https://developers.google.com/maps/documentation/javascript/reference/advanced-markers.md.txt#AdvancedMarkerElement)
and [`PinElement`](https://developers.google.com/maps/documentation/javascript/reference/advanced-markers.md.txt#PinElement)
classes.

The following snippet shows code to create a new `PinElement`, then apply it to
a marker.

```javascript
// Create a pin element.
const myPin = new PinElement({
    scale: 1.5,
});
// Create a marker.
const myMarker = new AdvancedMarkerElement({
    position: { lat: 37.4239163, lng: -122.0947209 },
});
// Append the pin to the marker.
myMarker.append(myPin);
// Append the marker to the map.
mapElement.append(myMarker);
```

In maps created using custom HTML elements, the basic parameters for a
marker are declared using the `gmp-advanced-marker` HTML element; any
customization that uses the `PinElement` class must be applied
programmatically. To do this, your code must retrieve the `gmp-advanced-marker`
elements from the HTML page. The following snippet shows code to query for a
collection of `gmp-advanced-marker` elements, then iterate through the results
to apply customization that was declared in the `PinElement`.

```javascript
// Return an array of markers.
const advancedMarkers = [...document.querySelectorAll('gmp-advanced-marker')];

// Loop through the markers
for (let i = 0; i < advancedMarkers.length; i++) {
  const pin = new PinElement({
      scale: 2.0,
  });

  marker.append(pin);
}
```

## Add title text

Title text appears when the cursor hovers over a marker. Title text is readable
by screen readers.

To add title text programmatically, use the `AdvancedMarkerElement.title`
option:


```javascript
// Default marker with title text (no PinElement).
const markerWithText = new AdvancedMarkerElement({
    position: { lat: 37.419, lng: -122.03 },
    title: 'Title text for the marker at lat: 37.419, lng: -122.03',
});
mapElement.append(markerWithText);
```

<br />

To add title text to a marker created using custom HTML elements, use
the `title` attribute:


```html
<gmp-map
    center="41.027748173921374, -92.41852445367961"
    zoom="13"
    map-id="DEMO_MAP_ID">
    <gmp-advanced-marker
        position="41.027748173921374, -92.41852445367961"
        title="Ottumwa, IA"></gmp-advanced-marker>
</gmp-map>
```

<br />

## Scale the marker

To scale a marker, use the `scale` option.


### TypeScript

```typescript
// Adjust the scale.
const pinScaled = new PinElement({
    scale: 1.5,
});
const markerScaled = new AdvancedMarkerElement({
    position: { lat: 37.419, lng: -122.02 },
});
markerScaled.append(pinScaled);
mapElement.append(markerScaled);
```

### JavaScript

```javascript
// Adjust the scale.
const pinScaled = new PinElement({
    scale: 1.5,
});
const markerScaled = new AdvancedMarkerElement({
    position: { lat: 37.419, lng: -122.02 },
});
markerScaled.append(pinScaled);
mapElement.append(markerScaled);
```

<br />

## Change the background color

Use the `PinElement.background` option to change the background color of a marker:


### TypeScript

```typescript
// Change the background color.
const pinBackground = new PinElement({
    background: '#FBBC04',
});
const markerBackground = new AdvancedMarkerElement({
    position: { lat: 37.419, lng: -122.01 },
});
markerBackground.append(pinBackground);
mapElement.append(markerBackground);
```

### JavaScript

```javascript
// Change the background color.
const pinBackground = new PinElement({
    background: '#FBBC04',
});
const markerBackground = new AdvancedMarkerElement({
    position: { lat: 37.419, lng: -122.01 },
});
markerBackground.append(pinBackground);
mapElement.append(markerBackground);
```

<br />

## Change the border color

Use the `PinElement.borderColor` option to change the border color of a marker:


### TypeScript

```typescript
// Change the border color.
const pinBorder = new PinElement({
    borderColor: '#137333',
});
const markerBorder = new AdvancedMarkerElement({
    position: { lat: 37.415, lng: -122.035 },
});
markerBorder.append(pinBorder);
mapElement.append(markerBorder);
```

### JavaScript

```javascript
// Change the border color.
const pinBorder = new PinElement({
    borderColor: '#137333',
});
const markerBorder = new AdvancedMarkerElement({
    position: { lat: 37.415, lng: -122.035 },
});
markerBorder.append(pinBorder);
mapElement.append(markerBorder);
```

<br />

## Change the glyph color

Use the `PinElement.glyphColor` option to change the glyph color of a marker:


### TypeScript

```typescript
// Change the glyph color.
const pinGlyph = new PinElement({
    glyphColor: 'white',
});
const markerGlyph = new AdvancedMarkerElement({
    position: { lat: 37.415, lng: -122.025 },
});
markerGlyph.append(pinGlyph);
mapElement.append(markerGlyph);
```

### JavaScript

```javascript
// Change the glyph color.
const pinGlyph = new PinElement({
    glyphColor: 'white',
});
const markerGlyph = new AdvancedMarkerElement({
    position: { lat: 37.415, lng: -122.025 },
});
markerGlyph.append(pinGlyph);
mapElement.append(markerGlyph);
```

<br />

## Use text in a glyph

Use the `PinElement.glyphText` option to replace the default glyph with a text
character. The text glyph of the `PinElement` scales with the `PinElement` and
its default color matches the default `glyphColor` of the `PinElement`.


### TypeScript

```typescript
const pinTextGlyph = new PinElement({
    glyphText: 'T',
    glyphColor: 'white',
});
const markerGlyphText = new AdvancedMarkerElement({
    position: { lat: 37.415, lng: -122.015 },
});
markerGlyphText.append(pinTextGlyph);
mapElement.append(markerGlyphText);
```

### JavaScript

```javascript
const pinTextGlyph = new PinElement({
    glyphText: 'T',
    glyphColor: 'white',
});
const markerGlyphText = new AdvancedMarkerElement({
    position: { lat: 37.415, lng: -122.015 },
});
markerGlyphText.append(pinTextGlyph);
mapElement.append(markerGlyphText);
```

<br />

## Hide the glyph

Set the `PinElement.glyphText` option to an empty string to hide a marker's
glyph:


### TypeScript

```typescript
// Hide the glyph.
const pinNoGlyph = new PinElement({
    glyphText: '',
});
const markerNoGlyph = new AdvancedMarkerElement({
    position: { lat: 37.415, lng: -122.005 },
});
markerNoGlyph.append(pinNoGlyph);
mapElement.append(markerNoGlyph);
```

### JavaScript

```javascript
// Hide the glyph.
const pinNoGlyph = new PinElement({
    glyphText: '',
});
const markerNoGlyph = new AdvancedMarkerElement({
    position: { lat: 37.415, lng: -122.005 },
});
markerNoGlyph.append(pinNoGlyph);
mapElement.append(markerNoGlyph);
```

<br />

Alternatively, set `PinElement.glyphColor` to the same value as
`PinElement.background`. This has the effect of visually hiding the glyph.
