CSS - Class not registering when combined with bootstrap - html

I have a weird one that I can't seem to be able to figure out. I am new to CSS and decided to use bootstrap to assist with styles etc.
the problem I have is when I try to assign two classes to a div element, 1 being the bootstrap column and another from my own stylesheet.
the code from my stylesheet seems to be ignored in some cases. now i have taken that one bit of code and css out and put it into the jsfiddle but it works fine. its only when combined with the rest of the html does it seem to have issues. also note that if i use inline styles it works...
I copied the entire code to js fiddle now so that you guys can replicate the issue. the section I am having issues with is the 4 images that are side by side
class="services-boxes"
anyway any assistance will be appreciated, as well as general feedback as I am new to this all! :)

Due to the way cascading style sheets work it (styles are be applied in order AND by specificity). It is most likely that styles you are expecting to see are being overridden by specificity.
Give this guide a read.
An example is that for <div id="selector">
#selector {background-color:red;}
div {background-color:green;}
You can expect to see a div with a red background, even though the green background is set afterwards, the id selector has greater specificity.
Then try and alter the specificity of your selectors in your css so that they will take precedence over in bootstrap.
Also just going to add, you have casing issues - you declare the class with lowercase in css, capitalised in your html.
You also have syntax issues in your css. Your css should look like:
.services-boxes {
padding:0;
max-height:500px;
width:100%;
}
Sort all this and you should be golden! jsfiddle

Looks like a combination of syntax errors. Your style should be declared like this:
.services-boxes {
padding:0px;
max-height: 500PX;
width:100%;
}
Note that the class is all lowercase (which should match style where declared which is currently Services-Boxes), a colon separating property and value (you has used = in some instances) and one set of curly braces per declaration (the above class .logo-image has 2 closing braces). Just a bit of formatting should see your code recognised

When you don't have total control over your HTML, you can use the !important property in css to give a priority to your styles.
.services-boxes {
color: red !important;
}
However keep in mind that you have to avoid the !important property as much as possible and do not use it unless you can't do it any other way.

Delete a CSS propery you dont have access to edit

I have made a complete Bootstrap grid system. I am now uploading my code to a CMS system, and can see there is some CSS from the backend, there is messing up my grid.
If I untick the following code in the inspector window, everything is looking perfect. When the following code is ticked in the inspector window everything is messed up. Is it possible to overwrite this code somehow, so the class is not used?
.cms-area img {
width: 100%;
}
You can use !important in such cases but use it sparingly. Best is to remove the unwanted code and not use !important. !important might cause issues later that are difficult to debug. If possible include your css after other css is included in the code. In CSS, rules that appear later take precedence over earlier rules
Edit:
Set width to auto instead of 100% to fix your alignment issue
Below given is the ideal way to manage css since it allows you to attribute your style content and lets you override the style already applied elsewhere.
.cms-area .your-class img {
width: <your choice>;
}

Which css style has least effect on an element?

Today I was trying to create a dummy css rule for testing and investigation.
.dummy {
some-style : somevalue;
}
Ideally the class should have no visible effect. I want to be able to apply the class to elements but cause the least visible effect possible on any elements it is applied to. For example
<div class="dummy"> should look and behaves as much as possible like <div>
I did not want the class to be empty. Can anyone suggest a style that I could add to the class that would have the least visible impact when applied to a general html element? I can't think of anything completely harmless.
UPDATE: I wanted to add the style to some existing html. The reason was to use the style as a marker for diagnostic purposes. It would help me see when and where styles and stylesheets were getting loaded/cached and where and why some styles were getting overridden, sometimes by the browser defaults which seemed odd. At the time I didn't have exclusive use of the system I was working on so I wanted something that was going to be invisible to other users but I could see in Developer Tools.
UPDATE 2 : the html/css wasn't written by me and I didn't have my own environment in which to work. I was trying to investigate some problems in-situ in someone else's system. I had tried using DevTools in the browser but wasn't getting anywhere with that. I wanted to be able to make some small changes to their html/css to aid my diagnostics. I didn't want them to have any obvious effect on the system for other people (except in DevTools, viewed by me).
It was a Wordpress site and they only had two environments, one for live and one for testing. I was working with the test system. There were other people testing at the time, though mainly checking content.
The real thorny problem was why was the font-size in the calendar widget much larger than everything else on the site? Inspecting using DevTools I could see the font-size style was getting overridden by the browser default style when it seemed to me there were other css selectors that should have taken precedence. It looked bizarre. In the end it turned out to be a missing !DOCTYPE tag in the html. So nothing to do with the css itself.
I didn't like this way of working, fiddling in someone's system, but there wasn't much else to do and it did help to resolve the problem for them.
Hopefully I don't have to do this again, but ever since I have been wondering what was the most harmless style that I could have used?
I thought I would ask here as there must be people who know CSS better than me.
You can use this:
.dummy{
min-width: 0;
min-height: 0;
}
If you just need anything beeing set you could assign rules that are default anyway. For block elements like div set
.block-class { display: block; }
And for inline elements like span
.inline-class { display: inline; }
Of course it could be an issue doing so in some rare cases but in general it's quite harmless I guess.
In principle, for any property you can have an arrangement like this:
div {
some-style : a-valid-value-for-some-style;
}
.dummy {
some-style : a-different-valid-value-for-some-style;
}
And .dummy's style will have an effect, no matter what some-style is.
Your best bet is to make use of CSS variables. These are custom properties and start with a double hyphen. so
.dummy {
--dummy-style: foo;
}
will make --dummy-style a property with value "foo". So long as you don't employ the variable as the value in another property, it will have no visible effect.

Font Awesome CSS overriding my CSS

I am working on a page - click here for link. The icons are all supposed to have the font size of .side-icon:
.side-icon{
font-size:28px;
}
BUT a style in font-awesome.css is overriding this, no matter where I include the library in the layout.
At the moment I have included the css in the top of a work around sheet (font-awesome-fix.css) using an #import, but I cannot get the 'font: normal normal normal 14px/1 FontAwesome;' to disappear at all.
Please help!
Make your selector more specific :
.side-icon.fa
See here how the priorities of the selectors are calculated.
Hey you should target the before element :
.side-icon:before{
font-size:28px;
}
maybe try adding an id to the specific .side-icon that you need to change the font on.
CSS:
.side-icon #id_goes_here{
font-size:14px;
}
Hope this helps!
The very helpful "!important" usually helps me solve issues like this, or at least determine the root issue:
.side-icon{
font-size:28px !important;
}
Try using more specific css to override the other styles. This may include adding classes or ids so you can chain them together to override.
Examples:
.side-icon.foo{styles}
#bar.side-icon{styles}
If that still doesn't work, you may want to use the !important override to add another layer of specificity. I wouldn't reccomend jumping to use it immediately, but that's mostly because i prefer to code more specifically than using !important everywhere.
Example:
.side-icon{style:value!important;}
If neither of these work, there may be other issues messing with your styles.
This is because of the CSS specificity rule kicks in:
When selectors have an equal specificity value, the latest rule is the
one that counts.
So including your file at the topmost location does not help because the font-awesome.css gets included later and since both .side-icon and .fa are classes on the same element, .fa defined by font-awesome.css got picked up by the browser because .fa was the latest font-size definition.
So, in order to overcome this problem, include your font-awesome-fix.css after font-awesome.css or you could use inline style after the line that includes font-swesome.css
<style>
.side-icon {
font-size: 28px;
}
</style>
or override the .fa font declaration in the same file (if you have control over it) by ensuring that the font-size override comes after the original declaration
or use one of the several ways to become more specific (see CSS specificity[1])

override CSS style or add to it?

I have a template that has a lot of CSS formatting, but now when I try to add my text I cannot add any formatting to it. Within a paragraph, I try to put superscripts, italics, but nothing works. Is there a way around this?
Here's a little explaination about overiding CSS
I'll take for my example this simple HTML :
<div id='home' class='current'></div>
If you have, for example, a css like
#home{color : blue;}
.current{color : orange;}
The text will be blue since #home is "stronger"
If we put values to selector: id=10 class=5 node selector (div) = 1
so #home = 10 and is higher than .current wich equal 5, #homestyles will override.
you could use li.current but again, 5+1=6 wich is lower than an id.
But #home.current will equal 15! Wich will overide #home styles!
But if your color style is on the node itself within the attribute style="" you have to remove it with jquery or use !important :
.current{
color: blue !important;
}
It will override EVERY css but it is not recommended.
Note that the value i am using are not the exact one, so .parentClass .class will maybe not over an id and i can't find the original values... But keep in mind that the more selective you are, the more chance you have to override a style.
At last, if you have 2 selector with the same value, the last one called will be the one overriding.
Use chrome inspector or firebug to see what's overriding what.

Replace html css style with condition from css file

I have this problem and I don't know how to fix it. In my project many html files have defined for div an width style, for example:
<div style="width:200px" id="boom">/*****/</div>
In css file if I put a condition like:
`div#boom{width:auto !important;}`
is ignored because style is defined in html for that div and from what I know html condition beat css condition.
How is possible to fix that? I don't want to edit all html pages because I would take a long time.
You are doing something wrong. Because !important makes the style the highest priority, so it always use the width: auto; and not the inline CSS.
An live example that this works: http://tinkerbin.com/wzrFiyaq
And a tutorial: http://css-tricks.com/override-inline-styles-with-css/
div[style] {
width:auto !important;
}​
