How can I do this(or something alike this) tooltip in only javascript without linking any template styles (I don't want to implement It to all the tooltips on the whole page). I'm designing the webpage on SharePoint which deletes all the ...

You can always add inline styles via JS.
var a = document.getElementsByClassName("class-name");
a.forEach(function(e) {
e.style.property = "value";
});
For adding :hover effects however, I think you need to append a stylesheet. Example.
Your other option is to use mouseover effects, but that is ridiculous when :hover exists.

I'm trying to modify (by CSS) the dark gray "Contact Us" button that's at the bottom right side of the following site: coloraddicted.com.
This is a button created by an external app, so the code is inaccessible. I only have the following (external) page to refer to for the possibility of finding the right id: https://icf.improvely.com/icf-button.js?v=1479350309&shop=coloraddicted-com.myshopify.com
How can I find the "id" of the specific element in order to apply the
"overriding" CSS to it?
BTW, I have already tried several versions of the id's I see on the above mentioned external page but still haven't found the right one.
I can't remember all of them, but some I have already tried are:
#icf_button
#icf.click_button
#icf_contact_form button {
#icf_contact_form add_button {
Style Contact button by css has no effect, because right after user hover, js code excuted & override on.
You can put js code at the end of the body, to re-override on the library code (not the good way, but have to), example
let contactButton = document.querySelector('#shop-colorful-products-printed-on-demand-just-for-you > div:nth-child(38)');
contactButton.style.backgroundColor = 'white';

If you can't modify the button.js script you linked to, I don't think you can target this (reliably) in CSS. They style everything with that button using inline styles and just append it to body.
You could potentially use :nth-of-type (like https://icf.improvely.com/icf-button.js?v=1479350309&shop=coloraddicted-com.myshopify.com) but that would be super unreliable as I'm assuming you have a bunch of scripts and stuff on the site that dynamically append to the page, creating a variable number of divs as direct descendants of body. FWIW, nth-of-type(13) worked for me.
The element doesn't have an id, so you can't select it that way. But the site appears to be using jQuery, so you could try using :contains() to target the element based on its contents:
$( "div:contains('Contact Us')" ).css( "font-size", "2em" );
But that would target any div containing the text "Contact Us". You can use :filter to select divs that contain only the text "Contact Us":
$("div").filter(function() {
return $.trim($(this).text()) === "Contact Us";
}).css("font-size", "2em");
You could use jQuery to either apply CSS directly, or to give the element an id. This solution is kind of kludgy, but might work in a pinch.
I have a situation where I am storing dynamic css data about a text object in a database as json. I need to map that same css data into styles in CKEditor. I am successfully able to load the classes into the CKEDITOR styles dropdown by parsing the json into the style set by running:
CKEDITOR.stylesSet.add('myStyles',styleObj);
Unfortunately this does not fully work with the onscreen text because the css does not exists as a file.
I've also successfully generate the css into the head of the dom by appending the dynamically generated css to a style tag. Unfortunately this still does not connect the actual css generated to the CKEDITOR because it is in a separate context.
Does anyone know how I can either connect document level css to the CKEDITOR instance or generate the CSS in a way that CKEDITOR understands? I'd prefer not to write a temporary CSS file to disk for every single user who needs to view the text object.
I figured out the answer to this by using the CKEDITOR.addCss() function.
Instead of trying to load the css into the document head as styles, the process can be much simpler by running CKEDITOR.addCss() function.
The code looks like:
for each css style found in the json:
styleObj.push({name:this.name,element:'p',attributes: { 'class':cssClassName}});
var cssSheetString = '.'+cssClassName+' {font-family:'+this.fontFamily+'; font-size:'+fontSize+'; font-weight:'+this.fontStyle+'; text-decoration:'+textDecoration+'; } ';
CKEDITOR.addCss(cssSheetString);
after the loop ends then also add the styles object:
if(!CKEDITOR.stylesSet.registered.myStyles){
CKEDITOR.stylesSet.add('myStyles',styleObj);
}
Just for posterity. I've seen answers that say this will work
CKEDITOR.on('instanceCreated', function (event) {
event.editor.addCss(styles);
});
but it does not, you have to use
CKEDITOR.on('instanceCreated', function (event) {
CKEDITOR.addCss(styles);
});
also if your styles variable changes you have to destroy and recreate your ckeditor instance with the new styles.
We've got a little tool that I built where you can edit a jQuery template in one field and JSON data in another and then hit a button to see the results immediately within the browser.
I really need to expand this though so the designer can edit a full CSS stylesheet within another field and when we render the template, it will have the CSS applied to it. The idea being that once we've got good results we can take the contents of these three fields, put them in files and use them in our project.
I found the jQuery.cssRule plugin but it looks like it's basically abandoned (all the links go nowhere and there's been no development in three years). Is there something better or is it the only game in town?
Note: We're looking for something where someone types traditional CSS stylesheet data in here and that is used immediately for rendering within the page and that can be edited and changed at will with the old rules going away and new ones used in their stead. I'm not looking for something where the designer has to learn jQuery syntax and enter in individual .css("attribute", "value") type calls to jQuery.
Sure, just append a style tag to the head:
$("head").append("<style>p { color: blue; }</style>");
See it in action here.
You can replace the text in a dynamically added style tag using something like this:
$("head").append("<style id='dynamicStylesheet'></style>");
$("#dynamicStylesheet").text(newStyleTextGoesHere);
See this in action here.
The cleanest way to achieve this is by sandboxing your user-generated content into an <iframe>. This way, changes to the CSS won't affect the editor. (For example, input { display:none; } can't break your page.)
Just render out your HTML (including the CSS in the document's <head>, and write it into the <iframe>.
Example:
<iframe id="preview" src="about:blank">
var i = $('#preview')[0];
var doc = i.contentWindow || i.contentDocument;
if (doc.document) doc = doc.document;
doc.open('text/html',true);
doc.write('<!DOCTYPE html><html>...</html>');
doc.close();
If the user should be able to edit a whole stylesheet, not only single style attributes, then you can store the entered stylesheet in a temporary file and load it into your html document using
$('head').append('<link rel="stylesheet" href="temp.css" type="text/css" />');
sounds like you want to write an interpreter for the css? if it is entered by hand in text, then using it later would be as simple as copy and pasting it into a css file.
so if you have a textarea on your page to type in css and want to apply those rules when you press the button, you could use something like this (only pseudocode, needs work):
//for each css id in the text area
$.each($('textarea[name=cssTextArea]').html().split('#'), function({
//now get each property
$.each($(this).split(';'), function(){
$(elem).css({property:value});
});
});
then you could write something to go through each element that your designer typed in, and get the current css rules for it (including those that you applied using some code like the snippet above) and create a css string from that which could then be output or saved in a db. It's a pain and much faffing around with substrings but unfortunately I don't know of a faster or more efficient way.
Hope this atleast gives you some ideas
I have a search page that is used in multiple places with multiple 'themes' throughout my site. I have a few divs that can have their background color changed based on a radio button selection (whether they are enabled or not). I can do this just fine by changing the css class of the div on the fly with javascript.
However, these themes could potentially change, and the background color is grabbed from a database when the page is created. Right now I do this in the C# codebehind:
string bgStyle = "background-color:" +theme.searchTextHeaderColor +";";
OwnerSearchHeader.Attributes.Add("style", bgStyle);
In the Javascript I need to change this color to make it look disabled, and when the user clicks back to this div I need to re-enable it by changing it back to its original color. But since I only knew this color in the code-behind, I don't know what it was in the Javascript.
So my thought was to create a css class in the resulting HTML page when the page is loaded with the background color I need. Then I could simply switch from the divEnabled and divDisabled class in the javascript. But I'm not exactly sure how to do that.
Alternatively I could create a hidden element, assign it the 'enabled' style, and use that as a reference in the JavaScript when enabling my div. This seems like a hack but maybe its the easiest way. I'm still new to a lot of this, so I'd appreciate any suggestions. Thanks for the input!

Yes, this is the anser; do this. In the <head> of your document add a <style> and put your CSS in there like so: (my Asp.NET is a little rusty so forgive me if it has some hicups ;) )
<style>
<!--
.divEnabled {
background-color:<%=theme.searchTextHeaderColor%>;
}
.divDisabled {
background-color:gray; /* or wtv */
}
-->
</style>
You could also put it in an external CSS file, which may be a good idea.
Then write some JavaScript to add/remove the class attribute (I'm going to ask that you don't call is the "CSS Class" ;) )
var ownersearchheader = document.getElementById("<%=OwnerSearchHeader.ClientId%>");
// changing the class attribute to `divDisabled`
var newClassAttribute = ownersearchheader.getAttribute("class").replace(/\bdivEnabled\b/, "divDisabled")
ownersearchheader.setAttribute("class", newClassAttribute);
// ... or,
// changing the class attribute to `divEnabled`
var newClassAttribute = ownersearchheader.getAttribute("class").replace(/\bdivDisabled\b/, "divEnabled")
ownersearchheader.setAttribute("class", newClassAttribute);
This is indeed a mouthfull, so, like #Haydar says, you might want to use jQuery, which offers easy-as-pie addClass(), removeClass() and toggleClass() methods.
You can use the jquery .toggleClass method.
Description: Add or remove one or more classes from each element in the set of matched elements, depending on either the class's presence or the value of the switch argument.
Here is the link to the api doc.
Jquery API
Is it possible to have 3-4 CSS on a page, and then on any event, say click, change the css for entire webpage. This way we can give our user the ability to change the theme. I know we can change the css of an element by:
$("#myElementID").removeClass("class1").addClass("class2");
Yes, it is possible. Typically what you would do is write a JavaScript function that will change, or add, or remove a style sheet from the <head> of the document. To make the experience a little better you'll typically store the user's preference in a cookie. There's an article on A List Apart that show how to implement this.
And of course, you can do this with jQuery... you may want to check out the source of jStyler.
The CSS Zen Garden (see the fifth question) ended up deciding that the easiest way was just to refresh the page and set a new CSS server side.
CSS is emdeded to DOM over 'link' tag, so you can locate this link and add/remove
Following code shows how to remove and add new one (I'm using MS AJAX see method $get, but you can replace it with pure DOM or other dialect):
var head = document.getElementsByTagName('head')[0];
var oldLink = $get("nameOfLink", head);
if(oldLink!=null)
head.removeChild(oldLink); //remove old entry
var s = document.createElement('link');
s.id="nameOfLink";
s.type = 'text/css';
s.rel="stylesheet";
s.charset ='utf-8';
s.href = "http://your-provided-url";
head.appendChild(s);
Usually best to load an external stylesheet (append a <link>): http://snipplr.com/view/3873/failsafe-load-for-attaching-stylesheet/
But if you need to create a bunch of styles on the fly, you can also build and append a <style> node to the DOM: http://jonraasch.com/blog/javascript-style-node
