HTML frameset tag

1. When the rows and cols value methods in frameset have only one row or one column, their corresponding values are 100%. A definite value (in pixels), for example, 50 defines the uplink, the row, and the downlink, and each of them occupies 50px? [Html] <frameset rows = "50, 50, 50"> <frameset rows = "50, 50, 50"> the above explanation is incorrect, the following example shows that the browser is divided by three (average) points. Therefore, we need to define that each of the three rows occupies 50 pixels. <frameset rows = "50, 50, 50, * "> This is defined. A value relative to the browser window percentage, for example, 50% defines the uplink and downlink, and each of them occupies 50% of the page [html] <frameset rows = "50%, 50% "> <frameset rows =" 50%, 50% "> use an asterisk (remaining form). For example, * defines the behavior of 50 pixels, the remaining form that occupies 50 pixels in the downstream [html] view plaincopyprint? <Frameset rows = "50, *"> <frameset rows = "50, *"> use relative percentages. For example, 1 * defines 25% of the height of the behavior form, 75% [html] <frameset rows = "1 *, 3 *"> <frameset rows = "1 *, 3 * "> the more complex example defines the first, middle, and rear columns of the level, and the column in the column is PX, the first and last columns account for 25% and 75% of the remaining [html] <frameset cols = "1 *, *"> <frameset cols = "1 *, 30% * "> defines a framework with two rows and three columns [html] www.2cto.com <frameset rows =" 70%, 33% "cols =" 34%, 33% "> <frameset rows =" 30%, 70% "cols =" 33%, 34%, 33% "> In the following example, we assume that the page height is 30% PX, and the first row's is PX, the upper-right behavior is 400px, and the remaining 300px is allocated by the following two instances. "2 *" means twice. "*" is equivalent to "1 *", so the lower-right behavior is 100px, behavior: 200px www.2cto.com [html] <CODE class = tag> </CODE> <CODE class = tag> frameset </CODE> <CODE class = attr> rows </CODE> <CODE class = tag >=</CODE> <CODE class = attrvalue> "</CODE> <CODE class = attrvalue> 30%, 400, *, 2 * </CODE> <CODE class = attrvalue> "</CODE> <CODE class = tag> </CODE> <frameset rows =" 30%, 400, *, 2 * ">
