If in my webpage, i have all the three css defined for a div
Inline
Internal
external
I know that browser first looks for 1)Inline then for 2)Internal and last, it looks for external css.
but i want to call only external css, how it would be done?? Can i do it through !important or there is any other way?
There is no difference between internal and external style sheets. Which styles are applied depends on:
Specificity
Declaration order
Inline styles are the most specific, then identity rules (#), then class rules (.), then element rules.
For two rules that have the same specificity, for example div .main and span.title, both rules apply, but the one declared last takes over when they specify the same properties.
The only way to circumvent the precedence is to use !important.
Best thing to do is to put everything into an external css file.
If you must have inline styling then make sure you only have ones that aren't already defined
in your external stylesheet. i.e Dont duplicate/override styling. e.g, if you have the following in your css file:
div { padding: 5px; }
then dont have the following inline styling.
<div style="padding-right:2px;" />
Just put it into the css file
div { padding: 5px 2px 5px 5px; }
Like you said, you can use !important if you have to override a styling for just one page that doesn't apply to the other pages in your site.
1)Inline then for 2)Internal and last, it looks for external css.
No. There is no difference in priority between CSS included with <style> and CSS included with <link>.
but i want to call only external css, how it would be done??
You cannot cause CSS included via <style> or CSS included via the style attribute to be ignored.
Can i do it through !important or there is any other way?
You could apply !important to every rule and then hope that no rule included via <style> or style also has !important… but that way lies madness.

I am using external style sheet more than one and internal css and also bootstrap predefined stylesheet. Now the problem is, I need 1 external style sheet would override all style sheets,internal css and inline css. how can i success it
You must use "!important" for your properties to override all styles
p {
padding: 10px !important;
}
There is precedence to css styling methods. Inline styles takes precedence over internal css (using <style></style> tags) and external css (using <link /> tag).
To force properties use !important keyword after your property value.
Example:
external.css
.home-page {
background-color: green !important;
}
PS: Check this question for more info:
What is the order of precedence for CSS?
You need to add/import external css which should override all the styles at the bottom. First add/import bootstrap, then add/import other css files, then your css file which should override others.
When Adding/Importing css files, order is important. The file you add/import at last will override the previous styles.
If something doesn't work as you expected, then give them important like this
h1 {
font-size: 25px !important;
}
In-line css rules always take precedence than other css rules/styles. In that case, you need to mark your rules with !important keyword.
There are several rules ( applied in this order ) :
inline css ( html style attribute ) overrides css rules in style tag and css file
a more specific selector takes precedence over a less specific one
rules that appear later in the code override earlier rules if both have the same specificity.
A css rule with !important always takes precedence.
Sourec: Details about precedence and css specificity is talked here
I am using a stylesheet in my code to stylize proprietary widgets, therefore I don't have access to alter the base stylesheet (nor is that really good practice anyway). One of the styles is causing problems in my application and I determined that the margin: 0 property needs to be removed entirely from this CSS rule:
.esriBasemapGallerySelectedNode .esriBasemapGalleryThumbnail {
border: 2px solid #F99;
margin: 0;
}
Is there a way to do this? Since I cannot view the stylesheet in a formatted way, I cannot get the index of this rule. The styles aren't in-line so I don't think I can use the .css() method. If I can't remove it, the only alternative I can think of is setting it to 1px (which I tested and it removed the problem that's occurring) but I'm not a big fan of that solution.
You will need to expand the specificity of your element if you do not wish to override css rules. The easiest way to do this is to add an id on an element and then write a css rule for that element using the id instead of the classes.

Suppose I have some html like this -:
<div style="blah...blah">Hey Nice</div>
<a style="blah...blah">Great</a>
How do I remove all the inline styling applied to the above elements in my stylesheet considering I don't know what all inline styling exists.
Currently I am trying this, but in vain -:
div[style], a[style]{ !important }
You must reset all css properties for elements that have style attribute:
[style] {
position: static !important;
float: none !important;
border: 0 none !important;
margin: 0 !important;
padding: 0 !important;
outline: 0 none !important;
// and so on
}
There are several determining factors determining which CSS property prevails in any situation. In order, these are:
Whether the property value has the !important flag or not.
If the style declaration is applied inline via the style attribute.
The strength of the CSS rule selector
If the rule has any ID clauses, and if so how many
If the rule has class, attribute or pseudo-class clauses, and if so how many
If the rule has any tagname clauses, and if so how many
If the property is parsed later in the source than another property with a rule of the same strength
So the only way to override the properties is to make sure that all the properties applied via style are applied elsewhere in your stylesheet, and have the !important declaration. The most rational way to do this is still very awkward — it would involve applying a very specific reset stylesheet, and including !important on every property on every rule.
But even if this is done, you still couldn't override inline style declarations that have !important themselves.
You've told Mojtaba that there should be a better solution, but that better solution would involve designing CSS to break its own rules. Imagine if there was a simpler solution for overriding inline styles from stylesheets designed into the language of CSS — should there also be another solution for simply overriding the override from inline styles? Where does the cycle end? All in all, I'd recommend using Javascript or giving up. Or describing your specific problem in more detail — there may be another solution!
If you're not happy with using !important overwrites in the CSS (as suggested by others on here), the only way would be to use JavaScript to remove the styles.
This is really easy in jQuery (better if you're able to assign a class name to the elements to select it with):
$('.selector').attr('style', '');
This will simply replace the element's 'style' attribute with nothing, thus removing the inline styles.
This isn't ideal though since it will rely on the visitor having JavaScript enabled, and may well result in the visitor seeing a style 'flash' as the page loads: the styles assigned in-line to the element before the JS kicks in and removes it.
I have one stylesheet (layout.css) that imports the following CSS at the top of the style sheet:
#import "reset.css";
#import "typography.css";
#import "forms.css";
#import "fonts/fonts.css";
#import "tablecloth.css";
Everything seems to be in order apart from that blasted typography style sheet. What I mean by that is when I apply a style to, say, a paragraph, the only styles applied to it are taken from the tyopgraphy style sheet.
Example:
Applied in layout.css:
#three-col-container #right-col.filter p.more { color: #ff0000; font-size: 1.2em; }
What Inspector is telling me is applied (these styles are included in the typography style sheet):
p { font-size: 1em; color: #444; }
I've never came across this sort of inheritance issue. The other style sheets are working as expected.
Any suggestions welcome.
Thanks.
You could try using the !important flag on the end of the rule you want to override, before the semicolon.
This will make sure it's always applied, and so should override the inherited rule.
#three-col-container #right-col.filter p.more means:
Apply this style to paragraphs (p) which have the more class that are descendants of something which has the id right-col and class filter that is descendant of something with id three-col-container.
Is this right?
Are you sure that in the typography stylesheet the style rules don't have the !important flag at the end? Are you that the URL of that stylesheet is correct?
It might be a specificity issue??
I found this awhile ago that's helpful when trying to determine css inheritance rules:
Add 1 for each element (ex p and a) and pseudo-element (ex :before and :after);
add 10 for each attribute (ex [type=”text”]),
class and pseudo-class (ex :link or :hover;
And add 100 for each ID;
and add 1000 for an inline style.
So #three-col-container #right-col.filter p.more has 2 ID's, 2 classes and 1 element, so it has a weight of 221.
Is it possible that there might be another rule that has a higher weight that's overriding your rule? Are there any other styles being applied other than those two? (Or even javascript applying inline rules?)
I try and use either Firebug or the Chrome/Safari Developer tools to try and figure out what rules are coming from where. Typically it'll give you the name of the css and the line the rule is on, the overridden rules will have a strikethrough. Once I figure out what rules are taking precedence I can raise or lower the weight of the rule to make it inherit properly.
Hopefully that helps!
Is there any way to apply a style that will effectively block the
application of any applied or inherited styles for that object and any
contained objects?
No. You'll have to override all other properties being set on it.
Write a style class i.e clearall override all the attributes that you need to what you want as the default vaules. i.e
.clearall {
display: block;
clear: both;
height: 1px;
margin: 0 0 0 0; ... }
Now, you can use that class to
<div class"clear">
<div class="awesome"> ..
</div>
</div>
<div class"clear">
<div class="woooow"> ..
</div>
</div>`
So now everytime that you need to reset the style, you can use that class
I would suggest to add at the end of your CSS code a complete reset code such as the one from Eric Meyer.
It should take care of erase most everything and and you can put your own code after that.
You can always can call !important on an element to override specificity inherits.
.wrapper p{color:red; background:blue;}
.wrapper div p{color:blue !important; background:none !important;}
Actually - no... But you can try to use jQuery for this purposes.
$('.class').removeClass().removeAttr('style');
It should remove all classes from matching elements and clear style attribute. Though, it's untested +)
If you want to do this for testing/debugging purposes, have a look at the Firefox Web Developer add-on. It has functions for removing CSS for whole pages or individual elements and their contained elements, or for altering CSS on the fly whilst viewing the page.
If you are looking for a good CSS reset for production use, have a look at Tripoli. This is a set of CSS styles that will reset the default rendering in each browser to the same common base, to use as a starting point for applying your own styles. There are many other CSS resets around but Tripoli is my personal favourite.
There‘s no one CSS property that turns off all other CSS properties. You’ll have to set each property to whatever value you want (for some CSS properties, e.g. font-family, there’s no “off” value — text has to be rendered in some font).
As for “that object and any contained objects” (emphasis mine), the * selector selects all elements. So, your CSS rule could look like this:
.turn-off-all-styles,
.turn-off-all-styles * {
/* Disable every CSS property here */
}
As others have mentioned, check out Eric Meyer’s CSS reset for a good example of setting all CSS properties to defaults. If you add !important after each value, that should stop other CSS rules from interfering with this style, e.g.
.turn-off-all-styles,
.turn-off-all-styles * {
margin: 0 !important;
...
}
