I have a custom cursor with some hover effects on a page (wordpress). This custom cursor shall hide, when hovering a certain div, due to some text. Please take a look here: https://florianwmueller.com/work-test/
I tried a lot, including some javascript, but nothing works. Any idea?
I gave the pictures a special class: .no-cursor
Thankful for any help...
Add this script on your website.
<script>
var elements = document.getElementsByClassName("no-cursor");
var style;
for (var i = 0; i < elements.length; i++) {
elements[i].addEventListener("mouseover", function() {
style = document.createElement("style");
style.innerHTML = "body.cursor-element-shape a { cursor: default !important; } .wpcc-active > .wpcc-cursor { display: none !important; }";
document.head.appendChild(style);
});
elements[i].addEventListener("mouseleave", function() {
document.head.removeChild(style);
});
}
</script>
I want to have these 2 attributes in a class on my stylesheet: target="_blank" and rel="noopener noreferrer"
The attributes work perfectly fine when I include them directly in a tag (example).
But when I try to put the 2 into a class (below), I get an error where target and rel are not recognized as attributes.
.link {
target: _blank
rel: noopener noreferrer
}
You need to do this using JavaScript, not CSS
Add an event listener to the document that waits for the document to be loaded, then get all of the elements with the .link class and set the relevant attributes.
document.addEventListener("DOMContentLoaded", function() {
var links = document.querySelectorAll(".link");
var numLinks = links.length;
for (var i = 0; i < numLinks; i++) {
var link = links[i];
link.setAttribute("target", "_blank");
link.setAttribute("rel", "noopener noreferrer");
}
});
Is there a way to hide a whole div if part of it is empty? For example if "dd" is empty as shown below can I hide the whole class "test" so the keyword Restrictions does not show either. I tried .test dd:empty { display: none; } but this does not work. thanks!
<div class="test"><dt>Restrictions:</dt>
<dd></dd></div>
I don't think there's any easy way to do what you're talking about with just CSS. Better to test it server-side if you can. But if you can't here's some JS that will do the job.
<script type="text/javascript">
// handles multiple dt/dd pairs per div and hides them each conditionally
function hideIfEmpty() {
// get all the elements with class test
var els = document.getElementsByTagName('dl');
// for every 'test' div we find, go through and hide the appropriate elements
Array.prototype.map.call(els, function(el) {
var children = el.childNodes;
var ddEmpty = false;
for(var i = children.length - 1; i >= 0; i--) {
if(children[i].tagName === 'DD' && !children[i].innerHTML.trim()) {
ddEmpty = true;
} else if(children[i].tagName === 'DT') {
if(ddEmpty) {
children[i].style.display = 'none';
}
// reset the flag
ddEmpty = false;
}
}
});
}
window.addEventListener('load', hideIfEmpty);
</script>
<div class="test">
<div style="clear: both;"></div>
<dl>
<dt>Restrictions:</dt>
<dd></dd>
<dt>Other Restrictions:</dt>
<dd>Since I have content, I won't be hidden.</dd>
</dl>
</div>
Just a fair warning: the code uses some functions that may not exist in older IE, such as Array.prototype.map, String.prototype.trim, and addEventListener. There are polyfills available for these and you could also write your own pretty easily (or just do it with a for loop instead).
CSS alone can't do that. Either, you need a javascript to retrieve empty elements and hide their parents, or your CMS applies special CSS classes if there's no content.
Put as an answer as requested by #Barett.
You could update your CSS to be
.test{
display: none;
color: transparent;
}
This would make the text transparent too, but display:none should hide it anyway.
To make the div with the id test ONLY show when the dd tag is EMPTY, and you can use jQuery, try the following JavaScript along with the CSS:
if($("dd").html().length ==0)
{show();
}
Note: this solution requires jQuery, which is a JavaScript library.
Question:
I need to add the internal style below to a Telerik Report. Please note a0 and a1 are classes.
The style sheet is given below: How do I convert this into an XML style sheet that a telerik report accepts.
Refer to : http://www.telerik.com/help/reporting/style-understanding-style-selectors.html
But the link does not give you detail on how to add a hyperlink selector into an XML style sheet.
CSS below:
a.a0:hover {
text-decoration: underline;
}
a.a1:link {
text-decoration: underline;
}
Below is how I worked around the above issue:
ReportViewer.prototype.OnReportLoadedOld = ReportViewer.OnReportLoaded;
ReportViewer.prototype.OnReportLoaded = function() {
this.OnReportLoadedOld();
var reportFrame = document.getElementById(this.reportFrameID);
var reportDocument = reportFrame.contentWindow.document;
var body = reportDocument.getElementsByTagName("body")[0];
$(".a1", body).css("text-decoration", "underline");
$(".a0", body).css("text-decoration", "underline");
You can achive the hover like this:
$(".a1", body).hover(function() {
$(".a1", body).css("text-decoration", "underline");
}, function () {
$(".a1", body).css("text-decoration", "underline");
});
I often find nice stylings on the web. To copy the CSS of a DOM element, I inspect that element with Google Chrome Developer Tools, look at the various CSS properties, and copy those manually to my own stylesheets.
Is it possible to easily export all CSS properties of a given DOM element?
Here is the code for an exportStyles() method that should return a CSS string including all inline and external styles for a given element, except default values (which was the main difficulty).
For example: console.log(someElement.exportStyles());
Since you are using Chrome, I did not bother making it compatible with IE.
Actually it just needs that the browsers supports the getComputedStyle(element) method.
Element.prototype.exportStyles = (function () {
// Mapping between tag names and css default values lookup tables. This allows to exclude default values in the result.
var defaultStylesByTagName = {};
// Styles inherited from style sheets will not be rendered for elements with these tag names
var noStyleTags = {"BASE":true,"HEAD":true,"HTML":true,"META":true,"NOFRAME":true,"NOSCRIPT":true,"PARAM":true,"SCRIPT":true,"STYLE":true,"TITLE":true};
// This list determines which css default values lookup tables are precomputed at load time
// Lookup tables for other tag names will be automatically built at runtime if needed
var tagNames = ["A","ABBR","ADDRESS","AREA","ARTICLE","ASIDE","AUDIO","B","BASE","BDI","BDO","BLOCKQUOTE","BODY","BR","BUTTON","CANVAS","CAPTION","CENTER","CITE","CODE","COL","COLGROUP","COMMAND","DATALIST","DD","DEL","DETAILS","DFN","DIV","DL","DT","EM","EMBED","FIELDSET","FIGCAPTION","FIGURE","FONT","FOOTER","FORM","H1","H2","H3","H4","H5","H6","HEAD","HEADER","HGROUP","HR","HTML","I","IFRAME","IMG","INPUT","INS","KBD","KEYGEN","LABEL","LEGEND","LI","LINK","MAP","MARK","MATH","MENU","META","METER","NAV","NOBR","NOSCRIPT","OBJECT","OL","OPTION","OPTGROUP","OUTPUT","P","PARAM","PRE","PROGRESS","Q","RP","RT","RUBY","S","SAMP","SCRIPT","SECTION","SELECT","SMALL","SOURCE","SPAN","STRONG","STYLE","SUB","SUMMARY","SUP","SVG","TABLE","TBODY","TD","TEXTAREA","TFOOT","TH","THEAD","TIME","TITLE","TR","TRACK","U","UL","VAR","VIDEO","WBR"];
// Precompute the lookup tables.
for (var i = 0; i < tagNames.length; i++) {
if(!noStyleTags[tagNames[i]]) {
defaultStylesByTagName[tagNames[i]] = computeDefaultStyleByTagName(tagNames[i]);
}
}
function computeDefaultStyleByTagName(tagName) {
var defaultStyle = {};
var element = document.body.appendChild(document.createElement(tagName));
var computedStyle = getComputedStyle(element);
for (var i = 0; i < computedStyle.length; i++) {
defaultStyle[computedStyle[i]] = computedStyle[computedStyle[i]];
}
document.body.removeChild(element);
return defaultStyle;
}
function getDefaultStyleByTagName(tagName) {
tagName = tagName.toUpperCase();
if (!defaultStylesByTagName[tagName]) {
defaultStylesByTagName[tagName] = computeDefaultStyleByTagName(tagName);
}
return defaultStylesByTagName[tagName];
}
return function exportStyles() {
if (this.nodeType !== Node.ELEMENT_NODE) {
throw new TypeError("The exportStyles method only works on elements, not on " + this.nodeType + " nodes.");
}
if (noStyleTags[this.tagName]) {
throw new TypeError("The exportStyles method does not work on " + this.tagName + " elements.");
}
var styles = {};
var computedStyle = getComputedStyle(this);
var defaultStyle = getDefaultStyleByTagName(this.tagName);
for (var i = 0; i < computedStyle.length; i++) {
var cssPropName = computedStyle[i];
if (computedStyle[cssPropName] !== defaultStyle[cssPropName]) {
styles[cssPropName] = computedStyle[cssPropName];
}
}
var a = ["{"];
for(var i in styles) {
a[a.length] = i + ": " + styles[i] + ";";
}
a[a.length] = "}"
return a.join("\r\n");
}
})();
This code is base on my answer for a slightly related question: Extract the current DOM and print it as a string, with styles intact
I'm quoting Doozer Blake's excellent answer, provided above as a comment. If you like this answer, please upvote his original comment above:
Not a direct answer, but with Chrome Developer Tools, you can click inside Styles or Computed Styles, hit Ctrl+A and then Ctrl+C to copy all the styles in those given areas. It's not perfect in the Style tab because it picks up some extra stuff. Better than selecting them one by one I guess. – Doozer Blake 3 hours ago
You can do the same using Firebug for Firefox, by using Firebug's "Computed" side panel.
There are a few ways to almost do this.
Have a look at FireDiff
Also have a look at cssUpdater This is for local CSS only]
And see this Q for more similar tools: Why can't I save CSS changes in Firebug?
Also this paid product claims to be able to do this: http://www.skybound.ca/
