A template can be understood as a model, which can be used to easily create many pages, and on this basis, each page can be modified to add personalized content. In order to unify the style, many pages of a website need to use the same page elements and layout methods. Using templates can avoid repeatedly entering or modifying the same parts in each page. When the website is revised, as long as the design of the template file is changed, all pages based on this template can be automatically changed. It can be said that one of the most powerful uses of templates is to update multiple pages at once. The document created from the template remains connected to the template Dreamweaver, Photoshop, Flash web page production and website construction essence (video intensive version) (unless the user separates the document later). You can modify the template and immediately update the design in all documents based on the template. Library files are used to convert objects commonly used in web pages into library files, and then insert them into other web pages as an object. In this way, you can create page content through simple insert operation. The template uses the entire web page, and the library file is only a part of the web page.
