This page shows what  CG Parallax module can do.

"Parallax effect" is used to call different layers moving at different speeds.You'll find templates calling this "OnePage effect".

CG Parallax module has 2 layers: (almost) fixed background image and scrolling articles. Background image + article = one section.

Every section may be directly accessed through module's menu. In this example, your menu is on the rightside of the screen, due to some CSS tricks : #cg_navbar, .cg_sticky{top:30%!important;width:10em;right:0;position:fixed;z-index: 9999;}

On the french demo page (showing component CG Parallax), our menu is under the main menu.

Please note:  this page has been created just for testing purpose, so I took 2 existing articles and added a small explanation.

Explanation of this page's behaviour.

This page uses CG Parallax module to display one page which contains multiple articles, each of them having a distinct background image.

Image+article) one section une section.

Each section may be easily customized through CSS code.

To create this page, I used 3 different images and I customized CG Parallax module using the following CSS code:

  • Menu on rightside, fixed
  • Images have been lightened using following values: sections 2 and 4 => image lighten : 5, section 3 => image lighten 4

module's CSS:

#cg_navbar, .cg_sticky{top:30%!important;width:10em;right:0;position:fixed;z-index: 9999;}
#cg_navbar ul, .cg_sticky ul {width:95%}
.cg_parallax h2 {color:white;background-color:lightslategray} 
.cg_parallax p{font-size:1.2em;background-color:lightgrey} 
.cg_parallax li {background-color: aliceblue} 

.cg_sticky : module's menu on rightside of the website, when scrolling page.
.cg_parallax h2 : section title with white characters on a grey background.


Explanation sections CSS: 

.cg_bg_img_3 p{font-size:1.1em;background-color: inherit}

.cg_bg_img_4 p{background-color:rgba(0, 0, 0, 0);}
.cg_bg_img_4 h3 {text-align:center;font-size:1.5em} 
.cg_bg_img_4 .phpcode {font-size:1em;line-height:1.1em}

.cg_bg_img_3 p and
.cg_bg_img_4 p
: no background in this section
.cg_bg_img_4 h3 : title with big character
.cg_bg_img_4 .phpcode : CSS code with bigger characters.
