Frames in HTML

Frame is a technique in which you can device you HTML browser into multiple sections (each section is called a frame) and display (load) separate web pages in each of them. So you can view multiple pages in a single browser.

To start with frames, one thing you must understand is there needs to be a container page that in itself does not load any webpage, but rather provides a template of frames.

Tags you will need:
<FRAMESET> </FRAMESET>

Attributes:


Cols:
This divides the browser into columns. That is split vertically. The value for this is the percentage division of the browser. For example "50%,50%" specifies that we need two columns each occupying 50% of the page.

Rows:
This divides the browser into rows. That is split horizontally. The value for this is the percentage division of the browser. For example "50%,50%" specifies that we need two rows each occupying 50% of the page.

Border:
Provides the thickness for frames borders.

Example:
<HTML>
 <FRAMESET rows="50%,50%" border="0">
 </FRAMESET>
</HTML>

But only this is not enough, as we have not told the browser which pages to load in the two frames that we just created. For this we need tag:

<FRAME> </FRAME>

Attributes:


Name:
The name of the frame. Very useful when we want a web page to target this particular frame. More on this is coming later.

Src:
The address of the page we will load.

MarginHeight:
The padding (margin) between the border of the frame and the page.

MarginWidth:
The padding (margin) between the border of the frame and the page.

Scrolling:
The scrolling effect for the frame.


Lets look at an example:

<HTML>
 <FRAMESET Rows="50%,50%" border="1">
  <FRAME Name="menu" Src="page1.html" MarginHeight="0" MarginWidth="0" Scrolling="auto">
  <FRAME Name="menu" Src="page2.html" MarginHeight="0" MarginWidth="0" Scrolling="auto">
 </FRAMESET>
</HTML>

WebPage:

As you can see the page is divided into two rows and the two frame tags occupy each of the frame in a sequential manner. So page 1 loads in frame 1 whereas page 2 loads in frame 2.

Lets divide the page into columns.

<HTML>
 <FRAMESET Cols="50%,50%" border="1">
  <FRAME Name="menu" Src="page1.html" MarginHeight="0" MarginWidth="0" Scrolling="auto">
  <FRAME Name="menu" Src="page2.html" MarginHeight="0" MarginWidth="0" Scrolling="auto">
 </FRAMESET>
</HTML>

WebPage:

Having both Rows and Columns in a browser:
Frames can be nested so that we can have a hybrid combination.

<HTML>
 <FRAMESET Cols="40%,*" border="1">
  <FRAME Name="menu" Src="page1.html" MarginHeight="0" MarginWidth="0" Scrolling="auto">
  <FRAMESET Rows="50,50" border="1">
   <FRAME Name="menu" Src="page2.html" MarginHeight="0" MarginWidth="0" Scrolling="auto">
   <FRAME Name="menu" Src="page3.html" MarginHeight="0" MarginWidth="0" Scrolling="auto">
  </FRAMESET>
 </FRAMESET>
</HTML>
