    <p>I think I've found a real solution. I've made it into a new function:</p> <p><code>jQuery.style(name, value, priority);</code></p> <p>You can use it to get values with <code>.style('name')</code> just like <code>.css('name')</code>, get the CSSStyleDeclaration with <code>.style()</code>, and also set values - with the ability to specify the priority as 'important'. See <a href="https://developer.mozilla.org/en/DOM/CSSStyleDeclaration" rel="noreferrer">this</a>.</p> <h2>Demo</h2> <pre><code>var div = $('someDiv'); console.log(div.style('color')); div.style('color', 'red'); console.log(div.style('color')); div.style('color', 'blue', 'important'); console.log(div.style('color')); console.log(div.style().getPropertyPriority('color')); </code></pre> <p>Here's the output:</p> <pre><code>null red blue important </code></pre> <h2>The Function</h2> <pre><code>(function($) { if ($.fn.style) { return; } // Escape regex chars with \ var escape = function(text) { return text.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, "\\$&amp;"); }; // For those who need them (&lt; IE 9), add support for CSS functions var isStyleFuncSupported = !!CSSStyleDeclaration.prototype.getPropertyValue; if (!isStyleFuncSupported) { CSSStyleDeclaration.prototype.getPropertyValue = function(a) { return this.getAttribute(a); }; CSSStyleDeclaration.prototype.setProperty = function(styleName, value, priority) { this.setAttribute(styleName, value); var priority = typeof priority != 'undefined' ? priority : ''; if (priority != '') { // Add priority manually var rule = new RegExp(escape(styleName) + '\\s*:\\s*' + escape(value) + '(\\s*;)?', 'gmi'); this.cssText = this.cssText.replace(rule, styleName + ': ' + value + ' !' + priority + ';'); } }; CSSStyleDeclaration.prototype.removeProperty = function(a) { return this.removeAttribute(a); }; CSSStyleDeclaration.prototype.getPropertyPriority = function(styleName) { var rule = new RegExp(escape(styleName) + '\\s*:\\s*[^\\s]*\\s*!important(\\s*;)?', 'gmi'); return rule.test(this.cssText) ? 'important' : ''; } } // The style function $.fn.style = function(styleName, value, priority) { // DOM node var node = this.get(0); // Ensure we have a DOM node if (typeof node == 'undefined') { return this; } // CSSStyleDeclaration var style = this.get(0).style; // Getter/Setter if (typeof styleName != 'undefined') { if (typeof value != 'undefined') { // Set style property priority = typeof priority != 'undefined' ? priority : ''; style.setProperty(styleName, value, priority); return this; } else { // Get style property return style.getPropertyValue(styleName); } } else { // Get CSSStyleDeclaration return style; } }; })(jQuery); </code></pre> <p>See <a href="https://developer.mozilla.org/en/DOM/CSSStyleDeclaration" rel="noreferrer">this</a> for examples of how to read and set the CSS values. My issue was that I had already set <code>!important</code> for the width in my CSS to avoid conflicts with other theme CSS, but any changes I made to the width in jQuery would be unaffected since they would be added to the style attribute.</p> <h2>Compatibility</h2> <p>For setting with the priority using the <code>setProperty</code> function, <a href="http://help.dottoro.com/ljdpsdnb.php" rel="noreferrer">This Article</a> says there is support for IE 9+ and all other browsers. I have tried with IE 8 and it has failed, which is why I built support for it in my functions (see above). It will work on all other browsers using setProperty, but it will need my custom code to work in &lt; IE 9.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
