This item is a key component in the <frame> tag. You need to have this in the frame portion in order for you to have frames. You can set them in cols and rows as well to determine the height and width of the frame itself. While I won't be able to show you physically, I can however give you the code on how it looks but keep in mind, you need the <frame> tag.

<frameset cols="70, *>

Required attributes


Frameset - most important aspect in the tag, this tells you where it begins and the address.
Cols - the purpose is to use it as a measurement in width. Don’t use pixels and go with percentages. You should have at least one *.
Rows - the values are still the same but it goes in a vertical sense. Think of it as the height of the frame. Can’t be on the same <frameset> tag as cols and vice versa.

Optional attributes


Аналог параметра border, задает ширину границы.

border - determines the depth of the border, it refers to the tables portion as that is where it is used most commonly.
bordercolor - if you have a border and want to change the color, this is the item to use. Like the border, this can be used in tables and the value has to be either a color or using hex value.
framespacing - it is analog of "border" parameter.
frameborder - show/hide a border between frame.

Example

<frameset rows="100, *" rows="150, *" frameborder=no border="10" bordercolor="#00FFFF"></frameset>
