+=== Gallery layout
+
+A **gallery layout** consists of two things: position and arrangement.
+
+* **Position** is about how the gallery is placed in the document. There are three possible positions, listed below. Note that they matter only on big screens. There is no difference on a phone.
+** `end` places the gallery at the end of line. By default, it is the right of the line. The text is wrapped around it.
+** `start` does the same thing, but places the gallery at the start, i/e left side.
+** `stretch` is the default position: the gallery is stretched to fit the document horizontally.
+* **Arrangement** is about how the images are placed in the gallery. There are two possible arrangements:
+** `grid` places the images in a grid.
+** `column` is the default arrangement: the images are in a vertical column.
+
+Specify the layout after `img` and before `{`. Just write the position and arrangement you need. If you do not write any of them, the default value will be used.
