Per https://api.jquery.com/category/selectors/
Child Selector (“parent > child”) Selects all direct child elements specified by “child” of elements specified by “parent”. Double check how you are referencing the parent and the children I grabbed this code from https://api.jquery.com/child-selector/, modified it and it works. Just remember that multiple elements can have the same css class, but each element must have a distinct css id. <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>child demo</title> <style> body { font-size: 14px; } </style> <script src="https://code.jquery.com/jquery-1.10.2.js";></script> </head> <body> <ul class="topnav"> <li>Item 1</li> <li>Item 2 <ul> <li>Nested item 1</li> <li>Nested item 2</li> <li>Nested item 3</li> </ul> </li> <li>Item 3</li> </ul> <ul id="topnav_id"> <li>Item 1</li> <li>Item 2 <ul> <li>Nested item 1</li> <li>Nested item 2</li> <li>Nested item 3</li> </ul> </li> <li>Item 3</li> </ul> <script> myChildren = $( "ul#topnav_id > li" ); myChildren.css( "border", "3px double blue" ); alert("With id " + myChildren.length); myChildren = $( "ul.topnav > li" ); myChildren.css( "border", "3px double purple" ); alert("With class " + myChildren.length); </script> </body> </html> Hope this helps.
