Help with using CSS id/class id's within MVC3 - html

Hello all I am trying to work through (learn) MVC3 and I was playing aroudn with formatting my view using CSS. When using html / webforms have been able to use div tags and apply to that div teh approiate css style.
When using MVC adn creating the layout in my view I have found that multiple CSS styles are not being inheritted.
for example: (sorry for the image but razor syntax seemed to fail on the code cut/paste
In the above I had a div tag for certain sections. however when I used the class property
<div class="myfirststyle" >some content</div>
for each of these div tags only the first one would be detected. The remaining div tags seemed to inherit from the main body style. also defined in the main CSS file.
Can anyone point me to some information on how to setup and style div tags within a view using CSS instead of the stylel property as shown in the above image OR is this correct as you cannot directly call CSS styles from a view as they are only recognized by the page layout.cshtml or masterpage?
Thanks in advance
Update: to help troubleshoot what is happening please refer to the following
Code within the view (using razor engine)
code within the CSS
output from developer toolbar notice how first div layer attributes are detected
output from developer toolbar notice now how image div does not have a style applied
What is interesting is that when viewing the source in html you can still see the CSS tags within the DIV tags they are just not being picked up or inherited for some reason after the first node/div tag
Thanks again for any pointers

Definitely not the case. Something else is going on.
Did you include your CSS file in the view or it's master page?
<link href="#Url.Content("~/Content/YourCSS.css")" rel="stylesheet" type="text/css" />
Or manually add the CSS to your view?
<style type="text/css">
div.myfirststyle { ... }
</style>
If so, have you confirmed the spelling of classes? Typos happen, and we can't see from your image whether or not you added classes to divs. Add some of your code even if you can't format it well enough :)

There is definitely something else funky going on... it has nothing to do with MVC*, it occurs when the browser tries to render it, so the problem must lie with the html & css.
If would recommend validating your HTML and CSS, this will show errors with missing closing tags or anything of the likes that can cause these sorts of errors.
I would recommend using Firefox or Chrome with the Web Developer Toolbar to make html & css validation easier.
*nothing to do with MVC directly... indirectly, sure.

Unfortunantly the error was all on my part. While I did have an error withiin my CSS file regarding the use of the position attribute within my styles. below is the updated style:
.resultController
{
position:static;
width:90%;
border: 1px solid #7C90BE;
margin:5px;
}
.resultImage
{
display:table-cell;
color:Green;
height:36px;
width:36px;
}
.resultContext
{
display:table-cell;
padding:3px;
left:50px;
color:Red;
}
.resultButtons
{
top:5px;
}
The larger problem (all my fault) was the browser was not purging teh cache on close. After dumping the cache and reloading the page the styles began to render correctly. Thanks to all for taking the time to look at this and offer your input.

Need help overriding button styling for slider from external CSS document

I am working on a project where I need to update the external CSS files for a webpage.
The problem is that I need to use a Marketo token to dictate what the new CSS style will be. Tokens do not work in external CSS files; I've tried.
I've been able to do most of this work myself, however, I am stuck at one element: a slider. I want to modify the color of the slider buttons to be determined by the Marketo tokens. I have tried "rebuilding" the slider section in the webpage html code, but so far no luck.
Any ideas?
This is a time-sensitive project, too.
Your help is greatly appreciated!
I understand you are trying to override previous css codes. Have you tried the following?
background-color: red !important;
Putting the link of the css file you want to be valid at the bottom.
deleting all the classes of the button related to javascript and adding new classes to style them.
.color{
color: red;
color: blue !important;
}
<div class="color">Color</div>
document.querySelector('.js-a').classList.add('js-b');
document.querySelector('.js-a').classList.remove('js-a');
.js-b{
color:blue;
}
.js-a{
color:red;
}
<div class="js-a">Javascript</div>

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>;
}

Modify div size with no access to html

I'm trying to edit some background on a page. I don't have access to the html file, only .css and .js. The page has a default theme that won't expand the background on the whole screen (bottom) because of the structure. I managed to swap the default background .png with an animated gradient through css but now I need to change the div. Tried with the #import url at the very top of the css file to call an external css but it won't work. Are there any ways to override the html structure? thank you
Forgot to say that I don't have access to the default template's css either. The service keeps everything on the server and once I installed the template in the local folder (the whole thing works with dropbox) I found an additional .css and .js in which I can add other code, though they come basically blank. What I need to do is to override the template's div structure from one of those 2 files. Using DevTools i found the name of the template div class and I guess I can download the relative .css. Still don't know how to override it... I'm not too familiar with coding in general...
Not clear with what you're trying to do. But you can always use Javascript DOM manipulation functions.
Check out this link for that: http://callmenick.com/post/basics-javascript-dom-manipulation.
You can also use jquery which provides better API.
If it is in some class definition or in a stylesheet file then use selector with high Specificity to get your definition on high priority
.oldclass{
width:328px;
height:328px;
background-image:url('http://via.placeholder.com/328x328');
}
/*Your New definition*/
div.oldclass{
background-image:url('http://via.placeholder.com/328x328');
}
<div class="oldclass">
</div>
If it is in inline style, then use !important tag
.oldclass{
width:328px;
height:328px
}
/*Your New definition*/
div.oldclass{
background-image:url('http://via.placeholder.com/328x328') !important;
}
<div class="oldclass" style="background-image:url('https://www.gravatar.com/avatar/fca24c2acab4d63343d4608ce256dcec?s=328&d=identicon&r=PG&f=1');">
</div>

CSS change to a squarespace site

Hi I'm using SquareSpace V6, with the Momentum template.
in this template there's an option to have the style of your gallery "full-bleed" or simply centered, but this setting is global and it applies to all the galleries on the website.
I'm trying to create some CSS code that will override the default and allow me to have a "full-bleed" gallery in the home page and the home page only, all the other ones will be left centered.
I've been inspecting the code with Chrome and I thought I had it, but nothing changes once I add my code to that specific page:
#collection-type-gallery { gallery-style:Full Bleed; }
Does anyone has experience with SquareSpace?
not exactly the answer I'm looking for.. but I found a workaround.
I created an empty page and added a background (with a snippet of code) to only that page.
(it only works if you want 1 single fullscreen image)
#collection-51b4ef7de4b0_use_your_own_here_62dc3410aaf3
{
background-image:url(http://static.squarespace.com/static/../background2.jpg);
background-repeat:no-repeat;
background-size:cover;
background-position:center;
}
You can call out the homepage specifically by using:
.homepage { }
or you can use a source code inspector and find the unique id as a class on the element and call out any individual page like so:
.collection-51b4ef7de4b062dc3410aaf3 { }

Injecting HTML via CSS

I need to basically set the content of something with HTML from CSS. I'm currently doing the following:
.myclass {
content "<img src=\"hello.png\"/>";
}
However, instead of the image, I see the literal text:
<img src="hello.png"/>
How can I inject arbitrary HTML using CSS?
HTML stores the data, and is the Model
CSS stores the styles, and is the View
JS stores the interactions, and is the Controller
If you're trying to add data to the page, it should be done via HTML. If you're simply trying to add an image as a style, use the background-image property. You don't need to inject an <img> element in the page to do that.
Don't ever do this, ever
As far as being able to inject HTML into the page via CSS, it's not directly possible, however it's possible to add JavaScript into the page using CSS, which can then add HTML to the page.
I can't emphasize enough how wrong that approach would be.
Unless there is some strange hack that I am not aware of, this cannot be done with pure CSS.
The content property is only able to insert text; if you try to put in HTML, it will be escaped.
That said, you can do something like this with pure CSS:
This is the CSS that can perform that effect:
.myClass:before {
display: inline-block;
width: 32px;
height: 32px;
content: "";
background-image: url("img.gif");
}
You can see this in action on this jsFiddle page.
In this particular case, you can use a pseudo-class (eg ::before), background-image, display:block and a fixed width and height to show the image.
Also, make sure that the colon : is added between content and its value.
A relatively new concept at the horizon is the element() value for backgrounds. This will display HTML as if it were an image: See also -moz-element.
This can be done. For example with Firefox
css
#hlinks
{
-moz-binding: url(stackexchange.xml#hlinks);
}
stackexchange.xml
<bindings xmlns="http://www.mozilla.org/xbl"
xmlns:html="http://www.w3.org/1999/xhtml">
<binding id="hlinks">
<content>
<children/>
<html:a href="/privileges">privileges</html:a>
<html:span class="lsep"> | </html:span>
<html:a href="/users/logout">log out</html:a>
</content>
</binding>
</bindings>

You can't. It's not what it's for. The CSS is for the presentation layer while the HTML is the data layer.
Actually, you can, but just for characters, not HTML. You can use the content property. With some CSS selectors like :before, you can do nice stuff like adding your own character as a bullet for your list. But not much more.
