// STRUCTURAL LAYOUT
// -----------------

body {
  margin: 0;
  font-family: @baseFontFamily;
  font-size: @baseFontSize;
  line-height: @baseLineHeight;
  color: @gray;
  background-color: @white;
}

// Container (centered, fixed-width layouts)
.container {
  .container-fixed();
}

// Fluid layouts (left aligned, with sidebar, min- & max-width content)
.fluid-container {
  position: relative;
  min-width: @siteWidth;
  padding-left: @gridGutterWidth;
  padding-right: @gridGutterWidth;
  .clearfix();
}

// Sidebars (left and right options)
.fluid-sidebar {
  width: @fluidSidebarWidth;
  margin: 0 20px 18px;
}
.sidebar-left   { padding-left: @fluidSidebarWidth + @gridGutterWidth * 2; }
.sidebar-right  { padding-right: @fluidSidebarWidth + @gridGutterWidth * 2; }

// Float the sidebars accordingly
.sidebar-left .fluid-sidebar {
  float: left;
  margin-left: (@fluidSidebarWidth + @gridGutterWidth) * -1;
}
.sidebar-right .fluid-sidebar {
  float: right;
  margin-right: (@fluidSidebarWidth + @gridGutterWidth) * -1;
}

// The main content area
.fluid-content {
  float: left;
  width: 100%;
}


// BASE STYLES
// -----------

// Links
a {
  color: @linkColor;
  text-decoration: none;
  &:hover {
    color: @linkColorHover;
    text-decoration: underline;
  }
}


// GRID SYSTEM
// -----------
// To customize the grid system, bring up the variables.less file and change the column count, size, and gutter there
.row {
  margin-left: @gridGutterWidth * -1;
  .clearfix();
}

// Find all .span# classes within .row and give them the necessary properties for grid columns 
// (supported by all browsers back to IE7)
// Credit to @dhg for the idea
[class*="span"] {
  .gridColumn();
}

// Default columns
.span1     { .columns(1); }
.span2     { .columns(2); }
.span3     { .columns(3); }
.span4     { .columns(4); }
.span5     { .columns(5); }
.span6     { .columns(6); }
.span7     { .columns(7); }
.span8     { .columns(8); }
.span9     { .columns(9); }
.span10    { .columns(10); }
.span11    { .columns(11); }
.span12    { .columns(12); }

// Offset column options
.offset1   { .offset(1); }
.offset2   { .offset(2); }
.offset3   { .offset(3); }
.offset4   { .offset(4); }
.offset5   { .offset(5); }
.offset6   { .offset(6); }
.offset7   { .offset(7); }
.offset8   { .offset(8); }
.offset9   { .offset(9); }
.offset10  { .offset(10); }
.offset11  { .offset(11); }
