The fluid grid style will display each row of your view within a fluid grid based on an HTML list element. You may customize the width and height of the items. You may also customize advanced layout options such as vertical and horizontal margins, several alignment options and a couple of CSS3 style properties (box-shadow and border-radius) for the items in the grid. A fluid grid looks like this:

Note however that the CSS3 style properties do not work on all browsers.

Stylesheets

The following stylesheets are provided:

You may want to use a different set of values for a few style plugin options. To do so, you need to add the proper entries to your settings.php file.
// Custom options for Views Fluid Grid style plugin.
$conf['views_fluid_grid_plugin_style_widths']  = array(
  100, 150, 180, 200, 250, 300, 350, 400, 450, 500,
);
$conf['views_fluid_grid_plugin_style_heights'] = array(
  100, 150, 200, 250, 300, 350, 400, 450, 500,
);
$conf['views_fluid_grid_plugin_style_margins'] = array(
  '0', '2px', '4px', '6px', '8px', '10px',
  '0.2em', '0.5em', '0.8em', '1em', '1.2em', '1.5em', '1.8em', '2em'
);
You can add more items to any of these variables to suit your needs. Then, you also need to provide the proper CSS classes. See the stylesheets shipped with this module to find out how these values match CSS classes. See examples for classes used for width and height in css/views_fluid_grid.size.css. Note that dots in $conf['views_fluid_grid_plugin_style_margins'] will be converted to dashes. See examples in css/views_fluid_grid.advanced.css. Examples:
/* This class is used for width 120. */
ul.views-fluid-grid-items-width-120 li.views-fluid-grid-item {
  width: 120px;
}

/* This class is used for horizontal margin 0.6em. */
ul.views-fluid-grid-items-h-margin-0-6em li.views-fluid-grid-item {
  margin-left: 0.6em;
  margin-right: 0.6em;
}
