+# generic COstum (templates)
+Imagine having created a costum (templateSlug)
+and you want to reuse exactly the same in a different context
+This is possible with *generic costums* with a parent element(elementSlug) 
+we can then use specific things from the parent element 
+
+The process means reusing a costum json file by many elements(organization, project, event ...) while using a costum attribute in the element's data map.
+on any element data, minimum : 
+```
+_id : "xxxxxelementID",
+slug : "elementSlug",
+costum : { 
+	//this is the parent costum , that can be overloaded
+	slug : "templateSlug" 
+}
+```
+all attributes inside this costum attribute will be identical to the parent
+```
+_id : "xxxxxelementID",
+slug : "elementSlug",
+costum : { 
+	slug : "templateSlug",
+	css : {
+		"font" : {
+            "url" : "/font/mayenneDemain/yourChosenfont.ttf"
+        },
+	}
+
+}
+```
+To see the costum we use the slug of the element 
+http://127.0.0.1/ph/costum/co/index/slug/xxxxSlugOfElement
+This loads the costum based on the parent costum slug 
+and in this process overloads any existing identical attributes
