Stop CSS transition from firing on page load

I'm experiencing an issue with the CSS transition property beeing fired on page load.

The problem is that when I apply a color transition to an element, (ex: transition: color .2s) then when the page first loads my elements flashes from black to it's own assigned color.

Supposing I have the following code:

CSS

p.green {
   color: green;
   transition: color .2s;
   -moz-transition: color .2s;
   -webkit-transition: color .2s;
   -o-transition: color .2s;
}

p.green:hover {
   color: yellow;
}

HTML

<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN'
'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'>
<html xmlns="http://www.w3.org/1999/xhtml" dir="ltr" lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
    <script src="js/main.js"></script>
    <link href="css/main.css" rel="stylesheet" />
</head>
<body>
    <p class="green">The Flashing Text</p>
</body>
</html>

On page load, my p.green will fade from black to green.

I don't want to apply the color transition to the :hover pseudo class as that would not apply the transition onMouseLeave.

I'ts really annoying having the text flashing across the webpage. Up to this moment I have been avoiding using transitions unless I really need them and even so I use with care. It would be great if there is some really obvious solution to this that I'm not seeing!

This happens on Google Chrome. I haven't tested in other browsers.

Solution 1:

There is a bug in Chrome that causes CSS transitions to fire if the page includes a <form> element.

One simple fix is to add a script tag containing a single space to the footer of the page.

<script> </script>

@Shmiddty comments on this question left me thinking, so I have been playing around with the code and found a solution.

The problem lies on the header declarations. By inverting the order of the CSS and JS external file calls - i.e. putting the CSS before the JS - the color transitions stop firing on page load:

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <link href="css/main.css" rel="stylesheet" />
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
    <script src="js/main.js"></script>
</head>

My guess is that the JS load was delaying the load of the CSS to after the DOM was ready. By that time (as @Shmiddty suggested) the text had already been assigned the default browser color and was then using my CSS transition declaration to fade into its styled color.

** I'm still not sure this is the most appropriate way to do it, but it works. If anyone has a better solution please feel free to add or edit.

Add to your CSS:

.css-transitions-only-after-page-load * {
  -webkit-transition: none !important;
  -moz-transition: none !important;
  -ms-transition: none !important;
  -o-transition: none !important;
  transition: none !important;
}

And add some code to your global JavaScript file:

$(document).ready(function () {
    $(".css-transitions-only-after-page-load").each(function (index, element) {
        setTimeout(function () { $(element).removeClass("css-transitions-only-after-page-load") }, 10);
    });
});

Now you can mark any element on your page with css-transitions-only-after-page-load class:

<div class="container css-transitions-only-after-page-load">
...
</div>
