Responsive Layouts

The Viewing Client interface was designed to adapt to any size viewport. Rather than targeting specific devices, the Viewing Client will fit to the maximum screen size on any device whether it is a desktop, tablet, or phone.

Media Queries

The Viewing Client utilizes CSS3 Media Queries (http://www.w3.org/TR/css3-mediaqueries/) with expressions using min-width and max-width to adjust the layout of navigation and dialogs.

Breakpoints

The Media Query Breakpoints, defined in viewer.css, are set according to the Viewing Client layout. On smaller viewports the tab navigation collapses into a menu and some tools are hidden. On larger viewports the dialogs transform from horizontal to a vertical layout to utilize screen real estate. The breakpoints are as follows:

Example
Copy Code
/* Target modern browsers that support media queries */
@media (min-width: 0) {}

/* Mobile & Tablet Sizes, collapse navigation tabs into menu */
@media (max-width: 767px) {}

/* Desktop Sizes */
@media (min-width: 768px) {}

Changing the Breakpoint

To change the breakpoint from the default 768px you will need to change this in two places:

1. In viewer.css, under the comment "viewport breakpoints", look for the following expressions:

Example
Copy Code
@media (max-width: 767px) {}
@media (min-width: 768px) {}

2. In viewer.js look for the variable tabBreakPoint; this is used in viewer.js to collapse the tab navigation on smaller viewports:

Example
Copy Code
this.tabBreakPoint = 767;

Legacy Support

Media Queries are not supported in Internet Explorer 8 and no Media Query polyfills are used in this regard. All Internet Explorer 8 specific styles are in legacy.css. Since Media Queries are not supported, if you add styles within a Media Query block in viewer.css you will also need to add this to legacy.css.

Grid System

The Viewing Client uses a basic grid system to assist with the UI layout. Through a series of rows and columns the layout can scale dynamically. Rows are used to create horizontal groups of columns. Columns are created by defining the number of twelve columns you will span. For example, three columns would use three divs with a class of .pcc-col-4:

Example
Copy Code
<div class="pcc-row">
    <div class="pcc-col-4">Left</div>
    <div class="pcc-col-4">Center</div>
    <div class="pcc-col-4">Right</div>
</div>

.pcc-col-* classes are active in small viewports and .pcc-lg-col-* classes only take effect in larger viewports:

Example
Copy Code
<div class="pcc-row">
    <!--
    These two divs will span one column on small viewports but
    split to two columns on larger viewports
    -->
    <div class="pcc-col-12 pcc-lg-col-6">Left</div>
    <div class="pcc-col-12 pcc-lg-col-6">Center</div>
</div>

There are also .pcc-hide and .pcc-show classes which can be used to toggle content across breakpoints:

Example
Copy Code
<div class="pcc-row">
    <!-- This button will only appear on larger viewports -->
    <button class="pcc-hide pcc-show-lg">Left</button>
    <!-- This button will only appear on smaller viewports -->
    <button class="pcc-show pcc-hide-lg">Center</button>
</div>
