Issue with element alignment using CSS increments

Question

Issue with element alignment using CSS increments

I'm confident that this code should be functioning properly, but for some reason it's not. I feel like there must be a small detail that I'm overlooking:

Markup:

<section id="content"></section>

Styling:

#content {
    position: relative;
    background: green;
    width: 300px;
    height: 150px;
    margin-top: 20px;
}

JavaScript:

$('#content').click(function(e) {
    if (e.ctrlKey)
        $(this).css('top', '50px');
    else
        $(this).css('top', '+=25');
});

If you ctrl+click, the content section moves correctly. However, clicking without holding ctrl does not increase the top position of the section by 25px. What could be causing this unexpected behavior?

$('#_testList').css('left', (parseFloat($('#_testList').css('left')) + 10) + 'px');

This script extracts the numerical value from a string - in this instance, it retrieves the 10 from 10px - adds 10 to it, and then appends 'px'. Remember, in CSS, the unit of measurement must follow the value.

I trust that clarifies things for you!

One potential solution is as follows:

$('#box').click(function(e) {
    if (e.shiftKey)
        $(this).css('left', '70px');
    else {
       var left = parseInt($(this).css('left'));
        left+=50;
        $(this).css('left',left)}
});

The method $(this).css('left') returns a string, so you need to parse it as an integer before adding 50px.
