Horizontal Rules

Horizontal Rules


	Horizontal rules appear as visible lines on a web browser. They're used to logically separate documents into separate sections to make them visually more appealing and easier to read. The htmlHorizontalRule class encapsulates the HTML <HR> tag.

	htmlHorizontalRule inherits from htmlObject. Therefore, it's intended to be added to other objects and does not accept objects on it's own.

	You can control the thickness of a horizontal rule using the Size() method. By default, horizontal rules are rendered across the entire width of the display area. If you do not want to use the entire width, the Width() method lets you specify the width as a percentage of the display, or as a fixed number of pixels.

Example Use

#include <stdio.h>

#include <stdlib.h>

#include <dcmicro/htmlpp/htmlpp.h>

int main( void )

{

   htmlCgi   server ;

   htmlPage  page( "html++ example application" ) ;

   page << "Default rule" << htmlHorizontalRule() ;

   htmlHorizontalRule   hr1 ;

   hr1.Width( "50%" ).Size( 10 ) ;

   page << "50% wide, 10 pixels thick" << hr1 ;

   htmlHorizontalRule   hr2 ;

   hr2.Width( 200 ).Shade( shade_shaded ) ;

   page << "200 pixels wide, shaded" << hr2 ;

   htmlHorizontalRule   hr3 ;

   hr3.Shade( shade_solid ).Align( align_right ) ;

   page << "Default width, solid, right-align" << hr3 ;

   server << page ;

   return 0 ;

}
