Using [matTooltip]="myMultiLineStringGenerator()" combined with [matTooltipClass]="'my-tooltip'" I was expecting to give me multi-line tooltips, whoever I get one liner tooltip, and I have no control when lines ends and moves to the next line.
Steps to reproduce
HTML part
<p [matTooltipClass]="'my-tooltip'"
[matTooltip]="getTooltopScript(nearestStations)">
Hello World!
</p>
CSS part:
.mat-tooltip {
white-space: pre-line;
}
::ng-deep .mat-tooltip {
white-space: pre-line;
}
TypeScript
getTooltopScript(ns: any[]]){
let part1 = ns[0]['stationName'] ;
let part2 = ns[0]['regionName'];
return `${part1}.\r\n\
${part2}.`;
}
I have read a lot other stack flows, and all of them where ending to use whitespace:pre-line in css, and \r\n in js\type script to create string. I dont know what else I should do make it work
Please help :)
update in CSS from other stackflows, and first comment below. I still have no result
::ng-deep .mat-tooltip .cdk-overlay-container, ::ng-deep .mat-tooltip .cdk-
global-overlay-wrapper {
white-space: pre-line;
}
If you are having the text coming from ts file, then please find below solution:
In .ts file:
getTooltopScript(){
return 'Multiline Tooltip \n This is second line';
}
In HTML:
<p #tooltip2="matTooltip" [matTooltip]="getTooltopScript()">Hello World!</p>
In css file:
::ng-deep .cdk-overlay-container, .cdk-global-overlay-wrapper {
white-space: pre-line;
}
In order to see the tooltip properly, we need to add the material style import in global stylesheet (that is style.css):
In style.css:
#import '~#angular/material/prebuilt-themes/deeppurple-amber.css';
Please find the working example below:
https://angular-sf-tooltip-issue-fix.stackblitz.io
https://stackblitz.com/edit/angular-sf-tooltip-issue-fix?file=src%2Fapp%2Fapp.module.ts
For this to work we need to override the style for .cdk-overlay-container, .cdk-global-overlay-wrapper:
::ng-deep .cdk-overlay-container, .cdk-global-overlay-wrapper {
white-space: pre-line;
}
In HTML:
<p matTooltip="Multiline Tooltip
This is second line">Hello World!</p>
Hope this will do the fix for you. Please find the working example below:

How to change the color only from text except everything is between tags ?
Sample text:
<b>A7</b> <b>D</b>
this is a test
<b>A7+</b> <b>G9</b>
this is a test
Assuming that all of that text is wrapped in a parent element (I've used <div>, but almost any other element would suffice), as such:
<div>
<b>A7</b>
<b>D</b>
this is a test
<b>A7+</b>
<b>G9</b>
this is a test
</div>
Then you can't change "all the text except the <b> tags", because CSS won't allow you to style the text without affecting the colour of the the <b> elements, you can, however, style the div and then 'unstyle' the b elements:
div {
color: #f00;
}
div b {
color: #000;
}
JS Fiddle demo.
To do this with jQuery (and, honestly, from the information you've posted jQuery seems unnecessary), you'd have to create wrapping elements for each of the strings of characters that are not wrapped in b elements and then directly style, or add a class to, those elements:
$('body').contents().filter(function(){
return this.nodeType === 3 && this.nodeValue.trim().length > 0;
}).wrap('<span />').parent().css('color','red');
JS Fiddle demo.
References:
contents().
filter().
parent().
wrap().
Try:
body{color:red;}
b{color:black;}
Fiddle here.
You could use jQuery like this:
$('body').css('color', '#FFCCFF');
$('b').css('color', '#000000');
But if you can do it in CSS it would be better:
body {
color: #FFCCFF;
}
b {
#000000;
}
Since you tagged this as jquery, I just provided a solution for this with jquery, You may wrap the html which was written by you in a paragraph tag like below. And then you have to use the .addClass function of Jquery to set different classes with different colours for that both paragraph and bold tag.
HTML
<p><b>A7</b><b>D</b>
this is a test
<b>A7+</b><b>G9</b>
this is a test</p>
CSS
.Paragraph{
color:red;
}
.boldtext{
color:black;
}
JQUERY
$('p').addClass('Paragraph');
$('p > b').addClass("boldtext");
DEMONSTRATION
I do not have access to the HTML or PHP for a page and can only edit via CSS. I've been doing modifications on a site and adding text via the ::after or ::before pseudo-elements and have found that escape Unicode should be used for things such as a space before or after the added content.
How do I add multiple lines in the content property?
In example the HTML break line element is only to visualize what I would like to achieve:
#headerAgentInfoDetailsPhone::after {
content: 'Office: XXXXX <br /> Mobile: YYYYY ';
}
The content property states:
Authors may include newlines in the generated content by writing the "\A" escape sequence in one of the strings after the 'content' property. This inserted line break is still subject to the 'white-space' property. See "Strings" and "Characters and case" for more information on the "\A" escape sequence.
So you can use:
#headerAgentInfoDetailsPhone:after {
content:"Office: XXXXX \A Mobile: YYYYY ";
white-space: pre; /* or pre-wrap */
}
http://jsfiddle.net/XkNxs/
When escaping arbitrary strings, however, it's advisable to use \00000a instead of \A, because any number or [a-f] character followed by the new line may give unpredictable results:
function addTextToStyle(id, text) {
return `#${id}::after { content: "${text.replace(/"/g, '\\"').replace(/\n/g, '\\00000a')} }"`;
}
Nice article explaining the basics (does not cover line breaks, however).
A Whole Bunch of Amazing Stuff Pseudo Elements Can Do
If you need to have two inline elements where one breaks into the next line within another element, you can accomplish this by adding a pseudo-element :after with content:'\A' and white-space: pre
HTML
<h3>
<span class="label">This is the main label</span>
<span class="secondary-label">secondary label</span>
</h3>
CSS
.label:after {
content: '\A';
white-space: pre;
}
I had to have new lines in a tooltip. I had to add this CSS on my :after :
.tooltip:after {
width: 500px;
white-space: pre;
word-wrap: break-word;
}
The word-wrap seems necessary.
In addition, the \A didn't work in the middle of the text to display, to force a new line.
worked. I was then able to get such a tooltip :
You may try this
#headerAgentInfoDetailsPhone
{
white-space:pre
}
#headerAgentInfoDetailsPhone:after {
content:"Office: XXXXX \A Mobile: YYYYY ";
}

For people who will going to look for 'How to change dynamically content on pseudo element adding new line sign" here's answer
Html chars like
will not work appending them to html using JavaScript because those characters are changed on document render
Instead you need to find unicode representation of this characters which are U+000D and U+000A so we can do something like
var el = document.querySelector('div');
var string = el.getAttribute('text').replace(/, /, '\u000D\u000A');
el.setAttribute('text', string);
div:before{
content: attr(text);
white-space: pre;
}
<div text='I want to break it in javascript, after comma sign'></div>
Hope this save someones time, good luck :)
Add line break to ::after or ::before pseudo-element content
.yourclass:before {
content: 'text here first \A text here second';
white-space: pre;
}
Found this question here that seems to ask the same thing: Newline character sequence in CSS 'content' property?
Looks like you can use \A or \00000a to achieve a newline
<p>Break sentence after the comma,<span class="mbr"> </span>in case of mobile version.</p>
<p>Break sentence after the comma,<span class="dbr"> </span>in case of desktop version.</p>
The .mbr and .dbr classes can simulate line-break behavior using CSS display:table. Useful if you want to replace real <br />.

Is there a way that I can select a textarea such that $('#id_of_textarea').val() in jQuery will be ''? I tried using :empty. I saw that CSS provides a way to select empty inputs because the text is in the value attribute ([value=""]). Is there an attribute for the text in a textarea?
I'm looking for a selector that will work with CSS, not just jQuery.
Best solution I can think of is a CSS 3 workaround. Set the field to required (and unset it on submit if need be). Then you can use
textarea:invalid { /* style here... probably want to remove box-shadow and such */ }
this works in recent browsers except edge (at the moment):
textarea:placeholder-shown {
/* this should be active only when area is empty and placeholder shown */
}
so with jQuery for example you can pick all empty textareas:
$('textarea:placeholder-shown').val()
https://developer.mozilla.org/en/docs/Web/CSS/:placeholder-shown
If you're using React, then this is the solution:
textarea:not(:empty) {
// Apply css here
}
For instance,
/* Apply style when textarea contains text */
textarea:not(:empty) {
border: 6px solid blue;
padding: 6px;
}
Working demo:
Textarea - Select empty textarea using CSS
Note: While this works perfectly in React (because of re-painting caused by state update), It does not provide the same response if implemented using Vanilla HTML + CSS.
This works fine, as with input:
<textarea name="comment" id="comment" class="authority_body-input" data-val="{$form.comment}" onkeyup="this.setAttribute('data-val', this.value);">
textarea.authority_body-input:not([data-val=""]):not(:focus) {
color: red;
}
You can use the :empty css pseudo-class.
See an example in jsfiddle.
In the example there is a button for dynamically add new empty textareas to the DOM, so you can see that the new elements also are affected with the pseudo-class.
The code in the example was tested in Firefox 5.0, Opera 11.50 and Chromium 12.
Also, you can see a good description for the :empty pseudo-class here.
For those who are using AngularJS, you can use ng-class in your view to add a class to your textarea to know if it is empty or not.
HTML :
<textarea ng-model="myForm.myTextArea"
ng-class="(myForm.myTextArea.length)?'not_empty':'empty'">
</textarea>
CSS :
textarea.empty {
background-color:red;
}
textarea.not_empty {
background-color:blue;
}
Here is a jsfiddle.
I would like to override setting that already defined with selecting
parent selector but I don't know how.
Say, there are 2 pages on a website like the following...
-Home page-
<body><h1 class="sifr">Home</h1></body>
-About page-
<body class="about"><h1 class="sifr">About</h1></body>
then, I have these in sirf-config.js...
sIFR.replace(fontname, {
selector: 'h1.sifr',
css: '.sIFR-root { color: #666666; font-size:29px; }'
});
sIFR.replace(fontname, {
selector: 'body.about h1.sifr',
css: '.sIFR-root { color: #FFFFFF; font-size:29px; }'
});
but it doesn't work...
If anybody help me I would appreciate.
Run the replacements for body.about h1.sifr before h1.sifr. sIFR doesn't calculate specificity but executes the replacements in-order. Replacing h1.sifr replaces all such elements, so body.about h1.sifr only finds elements that have already been replaced.
Check the order your loading CSS vs issuing the replace commands ...
I don't use Sifr, so I don't know exactly how it works. I assume that the code creates CSS code like this:
h1.sifr { color: #666666; font-size: 29px; }
body.about h1.sifr { color: #FFFFFF; font-size: 29px; }
If it does, that will override the color style for the heading in the about page, as the selector for the second line is more specific than the selector in the first line.
You can read more about specificity here.
If it doesn't work, it's because there is something in your code that doesn't look like you think it does, and it may very well be something in some other part of your code that you haven't shown here that is causing the problem.
You can use the Firebug plugin in Firefox to inspect the elements in the page to see exactly which css is affecting each element.
I have the following
<p class="main yellow">Hello World</p>
I would like to write a css element that refers to only elements with main and yellow. Is there a way to do this?
Eg. the following doesn't work, but would be what I'm after
.main + .yellow { color:green }
This should grab it:
.main.yellow { color:yellow; }
Though you may get differing results in different browsers. I use QuirksMode to get an idea of what will/won't work cross browser.
You just need to specify them as
.main.yellow { color: green; }
No space between the two classes.
does this work for you?
.main.yellow{
color:green;
}
As others have already said, what you want is:
.main.yellow { color:green; }
However, let me quickly explain why your first attempt didn't work. The + keyword refers to a following element, i.e. the element after.
Your example would have matched the following HTML...
<p class="main">Hello</p>
<p class="yellow">World</p>
...and styled the second paragraph (.yellow) green. So ".main + .yellow" means "select a .yellow that is immediately after a .main".
