       <p>The <code>.css()</code> method is a convenient way to get a style property from the first matched element, especially in light of the different ways browsers access most of those properties (the <code>getComputedStyle()</code> method in standards-based browsers versus the <code>currentStyle</code> and <code>runtimeStyle</code> properties in Internet Explorer) and the different terms browsers use for certain properties. For example, Internet Explorer's DOM implementation refers to the <code>float</code> property as <code>styleFloat</code>, while W3C standards-compliant browsers refer to it as <code>cssFloat</code>. For consistency, you can simply use <code>"float"</code>, and jQuery will translate it to the correct value for each browser.</p>
       <p>Also, jQuery can equally interpret the CSS and DOM formatting of multiple-word properties. For example, jQuery understands and returns the correct value for both <code>.css('background-color')</code> and <code>.css('backgroundColor')</code>. Different browsers may return CSS color values that are logically but not textually equal, e.g., #FFF, #ffffff, and rgb(255,255,255).</p>
-      <p>Shorthand CSS properties (e.g. margin, background, border) are not supported. For example, if you want to retrieve the rendered margin, use: <code>$(elem).css('marginTop')</code> and <code>$(elem).css('marginRight')</code>, and so on.</p>
+      <p>Retrieval of shorthand CSS properties (e.g., <code>margin</code>, <code>background</code>, <code>border</code>), although functional with some browsers, is not guaranteed. For example, if you want to retrieve the rendered <code>border-width</code>, use: <code>$(elem).css('borderTopWidth')</code>, <code>$(elem).css('borderBottomWidth')</code>, and so on.</p>
       <p><strong>As of jQuery 1.9</strong>, passing an array of style properties to <code>.css()</code> will result in an object of property-value pairs.</p>

       <p>As with the <code>.prop()</code> method, the <code>.css()</code> method makes setting properties of elements quick and easy. This method can take either a property name and value as separate parameters, or a single object of key-value pairs.</p>
       <p>Also, jQuery can equally interpret the CSS and DOM formatting of multiple-word properties. For example, jQuery understands and returns the correct value for both <code>.css({'background-color': '#ffe', 'border-left': '5px solid #ccc'})</code> and <code>.css({backgroundColor: '#ffe', borderLeft: '5px solid #ccc'})</code>. Notice that with the DOM notation, quotation marks around the property names are optional, but with CSS notation they're required due to the hyphen in the name.</p>
-      <p>When using <code>.css()</code> as a setter, jQuery modifies the element's <code>style</code> property. For example,  <code>$('#mydiv').css('color', 'green')</code> is equivalent to <code>document.getElementById('mydiv').style.color = 'green'</code>. Setting the value of a style property to an empty string &#x2014; e.g. <code>$('#mydiv').css('color', '')</code> &#x2014; removes that property from an element if it has already been directly applied, whether in the HTML style attribute, through jQuery's <code>.css()</code> method, or through direct DOM manipulation of the <code>style</code> property. It does not, however, remove a style that has been applied with a CSS rule in a stylesheet or <code>&lt;style&gt;</code> element. <strong>Warning:</strong> one notable exception is that, for IE 8 and below, removing a shorthand property such as <code>border</code> or <code>background></code> will remove that style entirely from the element, regardless of what is set in a stylesheet or <code>&lt;style&gt;</code> element.</p>

       <p>As of jQuery 1.6, <code>.css()</code> accepts relative values similar to <code>.animate()</code>. Relative values are a string starting with <code>+=</code> or <code>-=</code> to increment or decrement the current value. For example, if an element's padding-left was 10px, <code>.css( "padding-left", "+=15" )</code> would result in a total padding-left of 25px.</p>
       <p>As of jQuery 1.4, <code>.css()</code> allows us to pass a function as the property value:</p>
       <pre><code>$('div.example').css('width', function(index) {
