+### 6. Layouts
+
+* Always to keep 4 spaces of indentation between levels.
+* Prevent double indentation between element name and first property
+(which is a default behaviour of android studio)
+* Place `android:id` at the first position.
+* Place `style` after `android:id`.
+* Place `android:layout_width` and `android:layout_height` after `style`.
+* Try to keep similar order of properties in different layout's element.
+* Always use resources for values such as dimens, strings or colors.
