Question

Is there a way to change the CSS border of a div, when an input field gets focus (e.g. when it loses focus, remove the border).

HTML:

<input type="text" name="title" id="title"></input>
<div id="mainTitle">The Main Title</div>

CSS:

#mainTitle {
    border: 1px solid #ccc; 
}

Answer 1

$(function() {      //aka document.ready
    $("input#title").focus( function() {
        $("div#mainTitle").css("border","1px solid #ccc");
    });

    $("input#title").blur( function() {
        $("div#mainTitle").css("border","");
    });
});
