# Flat Polygons
To add a polygon to your Polygon post, press "Replace Drawing" and start to click on the map, clicking twice on a point to finish the polygon area. You can also upload a geoJSON if you prefer.
Flat polygons are standard polygons that just cover an area on the map. There are other types of polygons available as well (3D and image).
### Color
Set the color of the polygon.
### Opacity
Set the transparency of the polygon.
### Outline Color
The outline color is a 1 pixel border around polygons. Unfortunately the width *cannot* be adjusted. To make an adjustable border around your polygon, the best strategy is to make a line that has the same geography as your polygon.
### Hover Color *\[Pro]*
Color of polygon when hovered.
### Hover Opacity *\[Pro]*
Transparency of polygon when hovered.
### Hover Outline Color *\[Pro]*
Color of outer border when hovered.
