How to disable CSS in Browser for testing purposes
(19 answers)
Closed 7 months ago.
I am looking for an option based solution.
Of course there is an option to remove all style tags one by one from the elements panel, this will not remove inline injected styles.
For debugging purposes I would like this option to be at reach, I remember this being an option at one time.
For debugging you could try commenting out link tag in html body that has link to CSS stylesheet
You can do that on Firefox, found in the menu under View -> Website Style -> No Style (the wording might be slightly different, I don't have english version of FF installed but you should find it rather easily I guess.

Firefox developer tools adding a new rule?
(2 answers)
Closed 8 years ago.
The command I by far use the most in Firebug is right-clicking in the CSS pane and "Add Rule..."
Is there any quick equivalent in Firefox's Web Developer tools?
We've just added this to Firefox 33, see this bug for more info.
To try it out right now, download Firefox Aurora from http://aurora.mozilla.org/
Click on style editor tab. And add your css there.
Where it says:
element {
}
you should be able to just click there and add a rule. If the element has inline styles already applied to it, those braces won't be empty but you can do that same thing.

Stop CSS styles to be applied in particular sections of the code
HTML code inserted into WordPress with many plugins (each of them probably has it's own style) inherit global styles automatically.
An approach is to find unwanted styles and override them. Sometimes it's difficult to find it as in my case)
How can I define an HTML object to be clean from base and don't inherit any style from the page ?
According to the browser, it's the built in style: the border-spacing is set to 2px.
I think you meant to clear this with cellspacing=0, but the page is an HTML5 page, which doesn't support this attribute.
That said, there's some advice for you. Using tables for mark-up is outdated. You may get away with it, but if you are creating an html 5 page, you should obey the rules that come with it. :) It turns out that it isn't any of the WordPress CSS that is bothering you. It was just the built-in style, which could not be overruled using outdated attributes. :)
For the future, in most browsers you can inspect the elements and their properties. In Chrome this is built in, in FireFox I think you still need to install the FireBug plugin. With that, you can right-click -> inspect element and then check the element or its parent to see what is going on:

Detecting IE version using CSS Capability/Feature Detection
(18 answers)
Closed 5 months ago.
input,textarea,select{font-family:inherit;font-size:inherit;font-weight:inherit;}
input,textarea,select{*font-size:100%;}
This is from the YUI reset css. What does the * before font-size:100% do?
This is an IE hack. The second line is only correctly parsed and executed by IE 7 and below. See http://www.webdevout.net/css-hacks#unrecommended-asterisk_prefix for more information.
Edit: One remark on using such (invalid!) CSS: please don't. There are plenty of ways of keeping your CSS clean of such mess. You'll never know what behavior IE9 might bring. Better to put these kind of hacks in a separate CSS file which can then be included through conditional comments.
To be more precise: IE6/7 doesn't support font-size: inherit. This hack is supposed to achieve the goal anyway.
I think it's a hack to make that definition only apply to IE 7 or less while being ignored by other browser as an asterisk is not a legal character before an attribute name.
As already told, those are hack to target specific browsers. Marc's suggestion is quiet right, and here's a link to give you an kick start:

Here is a simple web based css optimizer, very useful:

Try ProCSSor
Make sure you have firebug (for Firefox, if you don't know), and then install the pagespeed plugin for firebug, developed by Google:
http://code.google.com/speed/page-speed/
It will give you a 'pageSpeed' tab in firebug. Open it and, with 'performance' selected, click 'analyze performance'. Along with lots of other useful suggestions, you will get a list item labelled "Remove Unused Css". Click to expand it and see a breakdown by resource of unused css rules appearing on the present page, along with the memory size that you will save by removing the unused rules.
You can try CSS Tidy:
http://csstidy.sourceforge.net/
It is simple yet effective.
