The document discusses HTML frames and how to structure a webpage using multiple frames. Frames allow dividing a browser window into sections to display different HTML documents. A common use is to have a menu frame on the left and content frame on the right. The document provides code examples for creating a basic frameset with two columns, adding a title banner frame above, and naming frames so links in one frame load the target page in another frame. Attributes like scrolling, border, and noresize customize frame properties.

- 1. WEBPROG1 – HTML Midterm Period Handout #6 HTML Frames Frames allow for multiple ".html" documents to be displayed inside of one browser window at a time. This means that one page has no content on it, but rather tells the browser which web pages you would like to open. Frames - A Generic Frame Page Frames are most typically used to have a menu in one frame, and content in another frame. When someone clicks a link on the menu that web page is then opened on the content page. Here is a classic example of a basic "index" frameset with a menu on the left and content on the right. Code: <html> <head> </head> <frameset cols="30%,*"> <frame src="menu.html"> <frame src="content.html"> </frameset> </html> o frameset - The parent tag that defines the characteristics of this frames page. Individual frames are defined inside it. o frameset cols="#%, *"- Cols(columns) defines the width that each frame will have. In the above example we chose the menu (the 1st column) to be 30% of the total page and used a "*", which means the content (the 2nd column) will use the remaining width for itself. o frame src="" -The location of the web page to load into the frame. A good rule of thumb is to call the page which contains this frame information "index.html" because that is typically a site's main page. Prepared By: RICHARD F. ORPIANO Page 1 of 4
- 2. WEBPROG1 – HTML Midterm Period Handout #6 Adding a Banner or Title Frame Add a row to the top for a title and graphics with the code as follows: <html> <head></head> <frameset rows="20%,*"> <frame src="title.html"> <frameset cols="30%,*"> <frame src="menu.html"> <frame src="content.html"> </frameset> </html> o frameset rows="#%, *"- rows defines the height that each frame will have. In the above example we chose the new title (the 1st row) to be 20% of the total page height and used a "*", which means that menu and content (which are the 2nd row) will use the remaining height. FrameBorder and FrameSpacing You probably noticed those ugly gray lines that appear between the frames. It is possible to remove these and manipulate the spacing between frames with frameborder and framespacing. These attributes appear within the frameset tag. Note: Framespacing and border are the same attribute, but some browsers only recognize one or the other, so use both, with the same value, to be safe. o frameborder="#" - A zero value shows no "window" border. o border="#"- Modifies the border width, used by Netscape. o framespacing="#" -Modifies the border width, used by Internet Explorer.

- 3. WEBPROG1 – HTML Midterm Period Handout #6 Code: <html> <head></head> <frameset border="0" frameborder="0" framespacing="0" rows="20%,*"> <frame src="title.html"> <frameset border="0" frameborder="0" framespacing="0" cols="30%,*"> <frame src="menu.html"> <frame src="content.html"> </frameset> </html> Frame Name and Frame Target How nice would it be to make each menu link load into the content page? We do this by naming each frame and setting the correct base target inside menu.html. Frame Code: <html> <head></head> <frameset rows="20%,*"> <frame name="title" src="title.html"> <frameset cols="30%,*"> <frame name="menu" src="menu.html"> <name="content" src="content.html"> </frameset> </html> menu.html Code: <html> <head> <base target="content"> </head> ... </html> We first named the content frame "content" on our frame page and then we set the base target inside menu.html to point to that frame. Our frame page is now a perfectly functional menu & content layout! Prepared By: RICHARD F. ORPIANO Page 3 of 4
- 4. WEBPROG1 – HTML Midterm Period Handout #6 Noresize and Scrolling It's possible to further customize the <frame> tag using the noresize and scrolling="" attributes. Code: <html> <head></head> <frameset border="2" frameborder="1" framespacing="2" rows="20%,*"> <frame src="title.html" noresize scrolling="no"> <frameset border="4" frameborder="1" framespacing="4" cols="30%,*"> <frame src="menu.html" scrolling="auto" noresize> <frame src="content.html" scrolling="yes" noresize> </frameset> </html> o noresize - Do not let the frames be resized by the visitor. o scrolling="(yes/no)"- Allow scrolling or not inside a frame. We set the scrolling for our content frame to yes to ensure our visitors will be able to scroll if the content goes off the screen. We also set the scrolling for our title banner to no, because it does not make sense to have a scrollbar appear in the title frame. Prepared By: RICHARD F. ORPIANO Page 4 of 4
