# Using Style in Xml

If the document is associated to a DTD that Amaya does not understand, the content of the document will be formatted and displayed in a way that reflects the structure of the document. If there is no style indication, the content of each element will be shown as a block. However, for clarity, the elements that have at least one child of type "texte" are considered to be of type inline and displayed accordingly. Amaya can use associate a CSS style sheet. You can also modify the presentation of the document if you associate a CSS style sheet to it by means of a xml-stylesheet PI (processing instruction) statement.
