The application discloses a method and an apparatus for typesetting in a manner of making a webpage adapt to a screen. The method provided by an embodiment of the application comprises: calculating the width of each node of a typesetting tree, limiting the width of the node with the width greater than that of a screen of an intelligent terminal, modifying the style of the node, and performing typesetting according to a rule of adapting to the screen; and not performing style processing on the node with the width less than or equal to that of the screen of the intelligent terminal, performing typesetting according to a standard flow, and reserving an original style of the node. Therefore, the original style of the page is more reserved on the basis of ensuring that the webpage adapts to the screen, and the page display has better effect and visual experience; and only the node with the width greater than that of the screen is typeset by adopting the rule of adapting to the screen, so that the conflict with the standard flow is not easily caused as a whole and the problems caused by difficult compatibility among various styles of writing in the page are reduced.
