LESS work around, grid system, box-sizing - css

unfortunately, I have to develop a site that is supported on IE7.
we know that IE7 does not support box-sizing:border-box; this is making me to specify width for every element separately in IE7 stylesheet.
I want to write some logic in my grid.less, so that the width will be calculated accordingly for ie7..
just like below
.grid{
width:/*width for modern browsers */;
*width:/*calculate width for ie7 */;
}
please help or point me to any resource.... thank you

LESS does not have a function to allow you to target specific browsers.
The standard method for doing this is with separate style sheets:
<link rel="stylesheet" type="text/css" media="screen" href="css/grid.css" />
<!--[if IE 7]>
<link rel="stylesheet" type="text/css" media="screen" href="css/ie7-grid.css" />
< ![endif]-->
But instead you can use a method like the following from Paul Irish:
html...
<!--[if lt IE 7]> <html class="ie6"> <![endif]-->
<!--[if IE 7]> <html class="ie7"> <![endif]-->
<!--[if IE 8]> <html class="ie8"> <![endif]-->
<!--[if gt IE 8]><!--> <html> <!--<![endif]-->
LESS...
.grid{
width:/*width for modern browsers */;
.ie7 & {
width:/*calculate width for ie7 */;
}
}
...which should result in css like...
.grid{
width:/*width for modern browsers */;
}
.ie7 .grid{
width:/*calculate width for ie7 */;
}

CSS conditional problems all IE vs the other browsers

How to write the sintax on the css property like:
.example{
/*all the browsers except IE*/
font-size:100%;
/*that's on all the IE syntax I need to add like a condition*/
font-size:200%
}
That's a simple code I know, that's only to test it, but not on the html, on each property in a class, id or tag on the css.
In ie6 it's:
#test{ _color: blue}
in ie6 and ie7:
#test{ *color: blue}
ie6, ie7 and ie8:
#test{ *color: blue\9}
But how to difference between all IE and the other browsers?
Anyone can help?
Use conditional stylesheets
Target IE 6 ONLY
<!--[if IE 6]>
<link rel="stylesheet" type="text/css" href="ie6.css" />
<![endif]-->
Target IE 7 ONLY
<!--[if IE 7]>
<link rel="stylesheet" type="text/css" href="ie7.css">
<![endif]-->
Target ALL VERSIONS of IE less than IE10
<!--[if IE]>
<link rel="stylesheet" type="text/css" href="all-ie-only.css" />
<![endif]-->
Target everything EXCEPT IE
<!--[if !IE]><!-->
<link rel="stylesheet" type="text/css" href="not-ie.css" />
<!--<![endif]-->
Since IE10 ignores conditional comments you can try this solution.

how to apply the height css property on ie9 just?

Can any one help me , please.
how to apply the height css property on ie9 just and do I can use conditional css inside css file?
You can't do conditional css in the css file, but you can give each version of IE its own class. Just put this at the top of the HTML file:
<!doctype html>
<!--[if !IE]> <html class="not-ie" lang="en"> <![endif]-->
<!--[if lt IE 7]> <html class="ie6" lang="en"> <![endif]-->
<!--[if IE 7]> <html class="ie7" lang="en"> <![endif]-->
<!--[if IE 8]> <html class="ie8" lang="en"> <![endif]-->
<!--[if IE 9]> <html class="ie9"><![endif]-->
<!--[if gt IE 9]><!--> <html lang="en"> <!--<![endif]-->
Now all you need to do in your css file to target ie9 is this:
.ie9 div.whatever {
height: some value;
}
I don't have a conditional CSS solution that can be done within the same CSS file. However, if you're not adverse to it, you could create a second CSS file specifically for IE9, and use conditional comments to apply the CSS. For example:
<link type="text/css" href="style.css" rel="stylesheet" />
<!--[if IE 9]>
<link type="text/css" href="style-ie9.css" rel="stylesheet" />
<![endif]-->
In this example, you would put whatever changes to height into "style-ie9.css". That stylesheet would only be applied when the browser is detected to be Internet Explorer 9.
Let me know if you have any questions, and I'll be happy to help further. Also, here's a link for more information on conditional comments, if you want a better understanding of them.
CSS Hack
As long as you do not want to set font or background just for IE 9 a combined :root hack will help
.somebox {
regular
definitions
here
}
:root .somebox{height:100px \ ;}
Conditional HTML Comment
Putting this in your head section after linking of the regular css file(s) will overwrite definitions only when IE 9 is used:
<!--[if IE 9 ]>
<link href="css/ie9only.css" type="text/css" rel="stylesheet"/>
<![endif]-->
ie9only.css must contain the IE 9 specific rules, of course.
Similar approach but using style tag instead of linking external file:
<!--[if IE 9 ]>
<style>.somebox{height:100px;}</style>
<![endif]-->

Disable css style for IE7 and IE8

I have style sheet file and would like to disable some css tags in it for IE7 and IE8 browsers, how to do that? I do not want to put these tabs in separated css file I would like to keep then in one file.
I'd recommend the approach taken by the HTML5 boilerplate, outlined here by Paul Irish. Basically, set up your document like this:
<!DOCTYPE html>
<!--[if lt IE 7]> <html class="no-js lt-ie9 lt-ie8 lt-ie7"> <![endif]-->
<!--[if IE 7]> <html class="no-js lt-ie9 lt-ie8"> <![endif]-->
<!--[if IE 8]> <html class="no-js lt-ie9"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js"> <!--<![endif]-->
You now have classes in place to accurately target only certain versions of IE. Your css will look like this:
.element { margin-bottom: 20px; }
.lt-ie8 .element { margin-bottom: 10px; }
You then avoid CSS hacks, and can keep everything in a single stylesheet.
As #Daniel states, this is not disabling styles, but over-riding them. If for some reason you want to send styles to only modern browsers and newer IE, you could add another class to the final html tag above, and use that.
If you try to have specific style-sheets only for IE it goes like this:
<!--[if IE 8]><link rel="stylesheet" href="css/ie8.css" type="text/css" media="screen"><![endif]-->
<!--[if IE 7]><link rel="stylesheet" href="css/ie7.css" type="text/css" media="screen"><![endif]-->
<!--[if IE]><link rel="stylesheet" href="css/ie.css" type="text/css" media="screen"><![endif]-->
More about this here: How To Create an IE-Only Stylesheet
.element {
margin-bottom: 20px;
margin-bottom: 10px\9;
}

You cannot disable them, but you can override them

Can we center those divs "IE7 and up" with variable width horizontally without using inline-block?

Without:
adding any markup element there;
without using display: inline-block;
without knowing the div width;
no hacks. the code should validate.
How can we center those three divs horizontally, but making them INLINE ?
http://jsfiddle.net/mMPMh/
Please note:
The reason that I'm avoiding inline-block, lies on the fact that IE7 should behave.
Other rules that don't work on IE 7 should also be disregarded.
Is it possible ?
Like this - http://jsfiddle.net/mMPMh/10/
Or this - http://jsfiddle.net/mMPMh/14/ ?
This one works with IE7
As for hacks, it can be served using conditional statement like
<!--[if lt IE 8]>
<link rel="stylesheet" type="text/css" href="ie7-and-down.css" />
<![endif]-->
Or using this on your HTML (from HTML5BP)
<!DOCTYPE html>
<!--[if lt IE 7]> <html class="no-js lt-ie9 lt-ie8 lt-ie7"> <![endif]-->
<!--[if IE 7]> <html class="no-js lt-ie9 lt-ie8"> <![endif]-->
<!--[if IE 8]> <html class="no-js lt-ie9"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js"> <!--<![endif]-->
And serve the style like this :
.lt-ie8 #one,
.lt-ie8 #two,
.lt-ie8 #three {
display:inline;
zoom:1;
}
No hacks
UPD:
After you update your questionyou can use for IE display:inline;, maybe it will resolve your issue?
Like this - http://jsfiddle.net/mMPMh/4/ ?
remove float, set clear, and give if you need height and width.

Is it possible to specify seperate Firefox and IE height?

I have two tables that need to line up side by side. In order to achieve this I have to specify a td height.
In IE the height should be 2.1em. In Mozilla it needs to be 1.76em.
There does not appear to be a
-moz-height:1.76em;
Any idea how I can achieve my goal?
You can put the IE height into a separate stylesheet and load it after the default one, using IE-conditional comments so the other browsers ignore it. Otherwise, you can use jQuery to change the height after it's loaded (if ($.browser.msie))
Yes it is. For Fire Fox do this:
#-moz-document url-prefix() {
//Your css here
#my-id { font-size: 100%; }
}
For IE you can do something like this:
[if IE 8]><link rel="stylesheet" href="DefaultSTyleForIE8.css" type="text/css" media="screen, projection"/><![endif]
This css will only work for IE 8
in mozilla it is possible to change the height for mozilla by height: -moz-calc(470px);
and auto height by height: -moz-available;
I would recommend the html5 boilerplate method,
<!-- paulirish.com/2008/conditional-stylesheets-vs-css-hacks-answer-neither/ -->
<!--[if lt IE 7]> <html class="no-js ie6 oldie" lang="en"> <![endif]-->
<!--[if IE 7]> <html class="no-js ie7 oldie" lang="en"> <![endif]-->
<!--[if IE 8]> <html class="no-js ie8 oldie" lang="en"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js" lang="en"> <!--<![endif]-->
then you can target ie in your css like,
.oldie #myel{
height: 2.1
}
I would shamelessly use IE conditional comments:
<style>
td {
height: 1.76em;
}
</style>
<!-- [if IE]>
<style>
td {
height: 2.1em;
}
<style>
<!endif-->
Here's a list of CSS filters by browser:
http://en.wikipedia.org/wiki/CSS_filter
Browser detect IE using IE's conditional comments and write out separate BODY tags:
<!--[if IE]><body class="ie"><!--<![endif]-->
<!--[if !IE]><!--><body><!--<![endif]-->
Then whenever you have a style, you can be more specific by adding the ie class to over-ride only IE:
.mystyle {styles for good browsers}
.ie .mystyle {styles for IE}
