Link Naar Tutorial Browser Targeting With Only Css
It’s every webdesigner’s nightmare: dealing with all the different browsers and their different versions interpreting your code differently. It goes without saying that we’re talking mainly about Internet Explorer, but I’ve come across differences in every browser. Luckily, there’s a ton of information out there on the Internet. Problem is, the specific information is not always easy to find. Or you’ve found it once, and you can’t find it again. So to save myself, and hopefully you, time, I’ve started a collection of browser targeting methods: Different ways to target a specfic browser (version). I.e. creating some code that is only used by a specific browser or browser version. For CSS, or otherwise (like conditional comments will allow you to use for example javascript only for IE).
By no means have I collected these tricks all by myself. I’ve used many sources over the years, and the large part of this list comes from Paul Irish and Cats that Code
The best way, is to always start with a CSS reset. What this does, is reset all items, so each browser sets out at the same starting point and then interprets your code. I always use Eric Meyer’s famous version:

// Add this code to the header just after the DOCTYPE declaration (as used in the TwentyEleven theme):
<!--[if IE 6]>
<html id="ie6" <?php language_attributes(); ?>>
<![endif]-->
<!--[if IE 7]>
<html id="ie7" <?php language_attributes(); ?>>
<![endif]-->
<!--[if IE 8]>
<html id="ie8" <?php language_attributes(); ?>>
<![endif]-->
<!--[if IE 9]>
<html id="ie9" <?php language_attributes(); ?>>
<![endif]-->
<!--[if !(IE 6) | !(IE 7) | !(IE 8) | !(IE 9) ]><!-->
<html <?php language_attributes(); ?>>
<!--<![endif]-->
All you now need to do is add IE specific code to your style.css file,
and add #ie7 before every entry to target IE7, etc.
#ie6 #twentythree { color: red }
#ie7 #twentyfour { color: red }
#ie8 #twentyfive { color: red }
#ie9 #twentysix { color: red }
.class {
width:200px; /* All browsers */ *width:250px; /* IE */ _width:300px; /* IE6 */ .width:200px; /* IE7 */}
/* IE6 */#twentyseven { _color: blue }
/* IE6, IE7 */#twentyeight { *color: blue; /* or #color: blue */ }
/* Everything but IE6 */#twentynine { color/**/: blue }
/* IE6, IE7, IE8 */#thirty { color: blue\9; }
/* IE7, IE8 */#thirtyone { color/*\**/: blue\9; }
/* IE6, IE7 -- acts as an */#thirtytwo { color: blue !ie; } /* string after ! can be anything */
/* IE8, IE9 */#thirtythree {color: blue\0/;} /* must go at the END of all rules */ Ofcourse you can also add conditional comments. In my opinion, though, it is better to add all of the CSS to one CSS file, as this keeps the number of HTML requests to a minimum. In some cases, though, you may want or need to use this (taken from the Quirksmode website ). More information can also be found here on MSDN.
You can use it to both target specific versions of IE, and everything BUT IE:
<!--[if IE]> According to the conditional comment this is IE<br /> <link href="ie.css" rel="stylesheet" type="text/css" /> <![endif]--> <!--[if IE 6]> According to the conditional comment this is IE 6<br /> <![endif]--> <!--[if IE 7]> According to the conditional comment this is IE 7<br /> <![endif]--> <!--[if IE 8]> According to the conditional comment this is IE 8<br /> <![endif]--> <!--[if IE 9]> According to the conditional comment this is IE 9<br /> <![endif]--> <!--[if gte IE 8]> According to the conditional comment this is IE 8 or higher<br /> <![endif]--> <!--[if lt IE 9]> According to the conditional comment this is IE lower than 9<br /> <![endif]--> <!--[if lte IE 7]> According to the conditional comment this is IE lower than or equal to 7<br /> <![endif]--> <!--[if gt IE 6]> According to the conditional comment this is IE greater than 6<br /> <![endif]--> <!--[if !IE]> --> According to the conditional comment this is not IE<br /> <!-- <![endif]-->
In some cases, you won’t make it with CSS only. Chrome for example, can be difficult to target without also targeting Safari.
<!-- Add this script to your header -->
<script type="text/javascript">
var is_chrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1;
if(is_chrome){
document.write('<link rel="stylesheet" href="/css/chrome.css" type="text/css" />');
}
</script>
A useful PHP code snippet which adds a different class to the body tag allows for a lot of freedom:
Add the following code to the functions.php file of your theme:
<?php
add_filter('body_class','browser_body_class');
function browser_body_class($classes) {
global $is_lynx, $is_gecko, $is_IE, $is_opera, $is_NS4, $is_safari, $is_chrome, $is_iphone;
if($is_lynx) $classes[] = 'lynx';
elseif($is_gecko) $classes[] = 'gecko';
elseif($is_opera) $classes[] = 'opera';
elseif($is_NS4) $classes[] = 'ns4';
elseif($is_safari) $classes[] = 'safari';
elseif($is_chrome) $classes[] = 'chrome';
elseif($is_IE) $classes[] = 'ie';
else $classes[] = 'unknown';
if($is_iphone) $classes[] = 'iphone';
return $classes;
?>
In case you need to detect several browsers, and you’re working with PHP, the Browser Detect class is a very useful tool for detecting more than 20 different browsers.
Download the package
You can also use jQuery to detect the most common browsers (Safari, Firefox, Chrome, IE and Opera): by using the browserdetect.js Jquery plugin.
The plugin will add a css class to your body tag, depending on the browser used by the visitor. For example, using FireFox 3 will result in the following body tag:
<body class="browserFirefox3">
I will add to this collection whenever I find new ways. If you have any to add, or a question, please leave your comment!
