The `coords` value contains a space where the validator expects the start of a number.

An `<area>` element defines a region in an image map. Its `coords` attribute describes that region using coordinates in CSS pixels. For `shape="poly"`, provide at least three pairs of x and y coordinates, with an even number of values.

In the example below, Rocket's HTML validator rejects the space immediately after the second comma. Write the coordinates as comma-separated numbers without spaces to avoid this parsing error. Keep the values appropriate for the selected shape.

## Invalid example

```html
<map name="floor-plan">
  <area shape="poly" coords="0,0, 100,0,100,50" href="/reception" alt="Reception">
</map>
```

## Valid example

```html
<map name="floor-plan">
  <area shape="poly" coords="0,0,100,0,100,50" href="/reception" alt="Reception">
</map>
```
