Overwrite template's stylesheet with the one from custom component in Joomla - joomla

In my custom Joomla 3 extension I am using Bootstrap 2.3.2 for the front-end. I noticed that the default Joomla template protostar overwrites default Bootstrap classes which is not what I would like. Is there a way to load my stylesheet after the template's stylesheets so they overwrite any common rules may exist?

Try something like this,
This will add the css at your component calling time inside the component HTML section . Keep in mind it will not add the css at head section but for sure it will appear after the template css
$stylelink = '<link rel="stylesheet" href="../css/css.css" />';
$document = JFactory::getDocument();
$document->addCustomTag($stylelink);
Hope it works..

How to add external libraries in joomla 3.8?

I need to include in my joomla project some external libraries but I don't understand how to do this.
However, I find that is necessary create a directory com_mycomponent and inside enter all files/folders js and css.
Ok, I do this but.. where I should tell joomla where they are?... I know that is necessary insert this lines:
JHtml::_('script', com_myComponent/js/file.js', false, true);
JHtml::_('stylesheet', 'com_myComponent/css/file.css', false, true);
but where I need to insert them?
Thank you so much
Joomla is very friendly Framework, Very simple to add external libraries
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" >
$document = JFactory::getDocument();
$document->addStyleSheet('https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css');
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/js/bootstrap.min.js"></script>
$document->addScript('https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/js/bootstrap.min.js');

Generate CSS or JS dynamically for a Joomla module

I am writing a Joomla module that includes a custom CSS stylesheet:
$document->addStyleSheet("modules/mod_custommenu/css/custommenu.css");
Now, this module needs to allow for customization of several CSS properties. I could include CSS inline in the module template, but I'd rather reference a separate file. I would like to:
Reference a separate CSS object (via URL)
Generate that CSS file using Joomla templates, like:
.custommenu_<?php echo $module->id; ?> .menutitle {
color: <?php echo $params->get('titlecolor'); ?>;
}
If possible, cache the rendered CSS file so Joomla doesn't need to generate it everytime it is accessed.
How can I do this? Or what is the correct approach for generating ad-hoc module CSS files?

How to make sure custom js file loaded last in joomla

I am trying to include a custom JS file into my joomla site. What I did is to edit the template's index.php file, and add <script src='custom.js"></script> right before </head>. But when the page is loaded, there are two other JS files loaded after my custom JS file. I thought by inserting my script loading line right before the closing head tag, my JS file should be the last one to load. What could possibly load those 2 JS files after my JS file, and how?
Try this,
you can use addCustomTag option this will not load the JS file inside your head tag but it should be last (from where you are calling there it load.)
$stylelink .= '<link rel="stylesheet" href="../css/IEonly.css" />';
$document = JFactory::getDocument();
$document->addCustomTag($stylelink);
For more details
Hope it works..
There is an option to specify execution of the script after page has loaded (defer). This is a HTML feature and addScript() exposes this in its interface. Doc: https://docs.joomla.org/JDocument/addScript
Example:
$document = JFactory::getDocument();
$document->addScript('js/myscript.js', 'text/javascript', true);

Problems specifying contentCss outside CKEditor.basepath

We are trying to use CKEditor as a Widget for Vignette, when we try to specify a content css outside the environment of CKEditor such as:
"CKEDITOR.config.contentsCss = 'http://lvhost:27110/CKEditorbk/my.css';"
doesn't work, but when we specify a content css included in the war where we have our deployment of ckeditor such as:
CKEDITOR.config.contentsCss = 'http://lvhost:27110/CKEditor/ckeditor/my.css';
It's working as we expected. Isn't possible to specify a css outside "CKEditor.basepath"?
In fact you can't because CKEditor path scope is anything within a folder named ckeditor.
However you could have your custom css outside the CKeditor's ckeditor by replicating the same folder structure, that is /js/CUSTOM_CKEDITOR/ckeditor. I've done so when I wrote a plugin for CKeditor.
I have a custom css at /js/CUSTOM_CKEDITOR/ckeditor/plugins/my_plugin/css/custom.css. And in my /js/CUSTOM_CKEDITOR/ckeditor/config.js I used:
CKEDITOR.config.contentsCss = CKEDITOR.plugins.getPath( 'my_plugin' ) + 'css/custom.css';
Works sweet :)

Joomla - Insert .js and .css files into a single Joomla article?

Is it possible for a single page on a Joomla website to include it's own custom .js and .css files?
I basically would like to add two custom javascript and css files for a particular page. I don't want these files included into any other Joomla pages.
Any suggestions would be appreciated.
Thank you
Try using a custom code extension such as JUMI. It is designed exactly for this purpose.
From the description: With Jumi you can include php, html, javascript scripts into the modules position, articles, category or section descriptions, or into your own custom made component pages.
The solution from Soygul wont result in proper HTML since these statements / includes belong to the HTML header.
Use : http://extensions.joomla.org/extensions/edition/custom-code-in-modules/11936
This plugin allows inserting material into the head section of your Joomla web site.
You can then use the menu assignment functionality to just add that to certain pages.
Its quite easy to write a simple module like that for yourself - but since this seems already available go with that one. If it doesn't fit your needs :
You just need an "empty / hello world" module with these two statements :
( http://docs.joomla.org/Creating_a_Hello_World_Module_for_Joomla_1.5 )
( http://docs.joomla.org/Adding_JavaScript_and_CSS_to_the_page )
// Add a reference to a Javascript file
// The default path is 'media/system/js/'
JHTML::script($filename, $path, $mootools);
// Add a reference to a CSS file
// The default path is 'media/system/css/'
JHTML::stylesheet($filename, $path);
I'm not a big fan of adding new extensions to Joomla unless absolutely necessary. If you do, make sure it's not on Joomla's list of vulnerable extensions, first. Each third-party extension/plugin you add is just one more potential back door for hackers.
To add your own custom CSS for a page, you can either edit your template's master CSS file, or just create your own and link it to the project. Here's how you'd do that:
First, figure out how your CSS files are being called. The actual file names will surely differ from my example, based upon the template you're using, but let's look at the Joomla SYSTEM template, which is located in templates/system. The index.php file controls everything, so open it up and you'll find this line:
<?php
include dirname(__FILE__).DIRECTORY_SEPARATOR.'component.php';
?>
Open component.php and you'll see some code that looks like this:
<head>
<jdoc:include type="head" />
<link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/system/css/general.css" type="text/css" />
You can see the call to include a CSS file in the 3rd line. All you need to do is add another line calling a CSS file you create. Create a new file called /templates/system/css/custom.css (or whatever you like) and rewrite the code segment in component.php to look like this:
<head>
<jdoc:include type="head" />
<link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/system/css/general.css" type="text/css" />
<link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/system/css/custom.css" type="text/css" />
Now you can just code out your own CSS in the new custom.css file you created. You can do this with any template system from RocketTheme or YooTheme just as easily. In fact, if you use one of their templates, they probably already have a custom.css file that you can simply add your own code to. Just be aware if you do it that way and then later update the template, you'll lose your code additions. That's why I prefer writing my own file. You can probably do something very similar to include custom JS code, but I tend to avoid JS like the plague, so someone else will have to address how to link out to a custom JS file.
