I am new to css and flex. Below is the working url in stackblitz.
https://stackblitz.com/edit/angular-ivy-bh8m8u?file=src/app/app.component.html
I have a left panel and main panel and a click button on the top of the page.
Requirement 1 On the click of the button i want to open the side panel. For some reason the side panel is not opening.
Requirement 2. I want to update the css to use flex if is possible because i am new to flex also
Please help.
Your sidePanelOpen variable isn't updating, and your sidePanel element is translated -150%, so it's off to the left of the screen
Never done any Angular but using the power of logic I've figured out half your answer. Now all you need to do is read a quick CSS tutorial
You originally were just setting this variable true. Using ! you can negate the sidePanelOpen value and get a toggle action going
.ts
openSideBar() {
this.sidePanelOpen = !this.sidePanelOpen;
console.log(this.sidePanelOpen);
}
Here you had the toggled class being set on the wrong element.
.html
<div [ngClass]="{'toggled' : sidePanelOpen}" class="sidebar" id="sidePanel">
<div>
<span id='close'>x</span>
<h4>Bangalore </h4>
</div>
</div>
Lastly, the toggled class won't do anything unless you have some css to hide your side panel
.css
#sidePanel.toggled {
display: none;
}
I am building a website and I'd like to add a link to a facebook page.
Designer has sent me a round image to represent the facebook link. Actually, the image is a rectangle, but the painting is round.
What I want is the pointer to change to the "link hand" only when over the round area of the image.
I could partially achieve that with this:
.imgFacebook {
border-radius:50%;
height:50px;
}
However the result I'm getting is: it is working for the image's top-side. In the top side, when I move the mouse outside the round, pointer gets back to an arrow.
The bottom side is still considering the image as a square image and changing the pointer outside the round design to a "hand", representing a link.
I have tried to set the border radius individually for each corner (top-left/right and bottom left/right), with no success.
So, does anyone knows how can I get a round area in my image as a link?
Thanks in advance
After some searches using different keywords, I was able to find a "how to" in this link.

I just had to add the image inside the div. As for the image I have used some style to make it display round as well.
<a href="http://www.wherelionsroam.co.uk" target="_blank">
<div id="a">
<asp:Image ID="imgLinkFacebook" runat="server" CssClass="imgFacebook"/>
</div>
</a>
.imgFacebook {
border-radius:50%;
height:50px;
}
Thanks anyway.
The title says it all. How do you go about doing this? For example, editing the width of a file upload button results in this: http://i.imgur.com/jacnps2.png For comparison, here's an ordinary file upload button: http://i.imgur.com/tIy05HA.png
The red rectangle represents the area the button normally takes up. In addition, when you hover your cursor over that spot (except for where the red and blue rectangles overlap), your cursor will transform into a hand icon, indicating that something will happen when you click that area. However, nothing happens.
The blue rectangle represents what portion of the screen you can click (which is mostly invisible, and much smaller than usual) to make the file upload form appear.
Trying to edit the file upload button's height yields similar results, only vertically instead of horizontally.
For the sake of explaining what my goal is: I'd like to overly a transparent or invisible file upload button on top of user avatars on my website. So far I've pulled off the easy parts, making the file upload button transparent and overlaying it on top of a user's avatar, but I haven't figured out how to edit the usable dimensions of the file upload button. For a working example of this, if you have a facebook profile, go to your profile and hover your mouse over your avatar. The words "Update Profile Picture" will appear and you can click them to edit your avatar directly from your profile instead of having to go to a separate settings page.
You can't style the file upload buttons, they are native to the browser and rendered differently in different browsers. All those styles file upload buttons are not actual file upload buttons but are simulating the file upload button's behaviour.
There are different approaches to this using CSS and Javascript. Most of them involve hiding the native button and placing a custom button on top it using position: absolute and opacity CSS properties and simulating the click on native button when clicked on the custom button.
As there are quite some solutions on the web to this, I will refer you to those instead of posting a solution here.

Cross-browser custom styling for file upload button
I did it with an after element and an icon from FontAwesome
# your-page.html.erb
<div>
<label class="button-image">
<%= f.file_field :attachment, value: "", class: "active-storage-button" %>
</label>
</div>
# app/assets/stylesheets/your-page.scss
.button-image:hover::after {
content: "\f196";
font: normal normal normal 100px/1 FontAwesome;
color: #778899;
padding: 10%;
right: 10%;
position: relative;
}
.active-storage-button{
display: none;
}
# for hover effect
.button-image:hover::after {
color: #5a5a5a;
cursor: pointer;
}
I have an html page where we have images,text and two buttons
1.print page for printing the page
2.Hide/Show(toggle button) for hide/show below the image.
image in the page are generated dynamically using remote service.
In Google-Chrome
When I click Hide/Show button to hide image and click print button,print preview page comes on the same page.
Then I cancel print page and back to page.
Then I again click Hide/Show button to show image
here the problem is that image is not shown on the page.
Using firebuglite I found that inline css style like width and height for image are 0 and hence image is not shown on the page.
How can I manage the css style for image after print preview and this problem occurs only in Chrome.
Please help.
here is CSS Browser Selector using javascript:
http://rafael.adm.br/css_browser_selector/
you can use that,then add the class:
.chrome #btn{
height:30px !important;
width:100px !important;
}
I have a div that has background:transparent, along with border. Underneath this div, I have more elements.
Currently, I'm able to click the underlying elements when I click outside of the overlay div. However, I'm unable to click the underlying elements when clicking directly on the overlay div.
I want to be able to click through this div so that I can click on the underlying elements.
Yes, you CAN do this.
Using pointer-events: none along with CSS conditional statements for IE11 (does not work in IE10 or below), you can get a cross browser compatible solution for this problem.
Using AlphaImageLoader, you can even put transparent .PNG/.GIFs in the overlay div and have clicks flow through to elements underneath.
CSS:
pointer-events: none;
background: url('your_transparent.png');
IE11 conditional:
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src='your_transparent.png', sizingMethod='scale');
background: none !important;
Here is a basic example page with all the code.
Yes, you CAN force overlapping layers to pass through (ignore) click events.
PLUS you CAN have specific children excluded from this behavior...
You can do this, using pointer-events
pointer-events influences the reaction to click-, tap-, scroll- und hover events.
In a layer that should ignore / pass-through mentioned events you set
pointer-events: none;
Children of that unresponsive layer that need to react mouse / tap events again need:
pointer-events: auto;
That second part is very helpful if you work with multiple overlapping div layers (probably some parents being transparent), where you need to be able to click on child elements and only that child elements.
Example usage:
.parent {
pointer-events:none;
}
.child {
pointer-events:auto;
}
<div class="parent">
I'm unresponsive
I'm clickable again, wohoo !
</div>
Allowing the user to click through a div to the underlying element depends on the browser. All modern browsers, including Firefox, Chrome, Safari, and Opera, understand pointer-events:none.
For IE, it depends on the background. If the background is transparent, clickthrough works without you needing to do anything. On the other hand, for something like background:white; opacity:0; filter:Alpha(opacity=0);, IE needs manual event forwarding.
See a JSFiddle test and CanIUse pointer events.
I'm adding this answer because I didn’t see it here in full. I was able to do this using elementFromPoint. So basically:
attach a click to the div you want to be clicked through
hide it
determine what element the pointer is on
fire the click on the element there.
var range-selector= $("")
.css("position", "absolute").addClass("range-selector")
.appendTo("")
.click(function(e) {
_range-selector.hide();
$(document.elementFromPoint(e.clientX,e.clientY)).trigger("click");
});
In my case the overlaying div is absolutely positioned—I am not sure if this makes a difference. This works on IE8/9, Safari Chrome and Firefox at least.
Hide overlaying the element
Determine cursor coordinates
Get element on those coordinates
Trigger click on element
Show overlaying element again
$('#elementontop').click(e => {
$('#elementontop').hide();
$(document.elementFromPoint(e.clientX, e.clientY)).trigger("click");
$('#elementontop').show();
});
I needed to do this and decided to take this route:
$('.overlay').click(function(e){
var left = $(window).scrollLeft();
var top = $(window).scrollTop();
//hide the overlay for now so the document can find the underlying elements
$(this).css('display','none');
//use the current scroll position to deduct from the click position
$(document.elementFromPoint(e.pageX-left, e.pageY-top)).click();
//show the overlay again
$(this).css('display','block');
});
I currently work with canvas speech balloons. But because the balloon with the pointer is wrapped in a div, some links under it aren't click able anymore. I cant use extjs in this case.
See basic example for my speech balloon tutorial requires HTML5
So I decided to collect all link coordinates from inside the balloons in an array.
var clickarray=[];
function getcoo(thatdiv){
thatdiv.find(".link").each(function(){
var offset=$(this).offset();
clickarray.unshift([(offset.left),
(offset.top),
(offset.left+$(this).width()),
(offset.top+$(this).height()),
($(this).attr('name')),
1]);
});
}
I call this function on each (new) balloon. It grabs the coordinates of the left/top and right/down corners of a link.class - additionally the name attribute for what to do if someone clicks in that coordinates and I loved to set a 1 which means that it wasn't clicked jet. And unshift this array to the clickarray. You could use push too.
To work with that array:
$("body").click(function(event){
event.preventDefault();//if it is a a-tag
var x=event.pageX;
var y=event.pageY;
var job="";
for(var i in clickarray){
if(x>=clickarray[i][0] && x<=clickarray[i][2] && y>=clickarray[i][1] && y<=clickarray[i][3] && clickarray[i][5]==1){
job=clickarray[i][4];
clickarray[i][5]=0;//set to allready clicked
break;
}
}
if(job.length>0){
// --do some thing with the job --
}
});
This function proofs the coordinates of a body click event or whether it was already clicked and returns the name attribute. I think it is not necessary to go deeper, but you see it is not that complicate.
Hope in was enlish...
Another idea to try (situationally) would be to:
Put the content you want in a div;
Put the non-clicking overlay over the entire page with a z-index higher,
make another cropped copy of the original div
overlay and abs position the copy div in the same place as the original content you want to be clickable with an even higher z-index?
Any thoughts?
I think the event.stopPropagation(); should be mentioned here as well. Add this to the Click function of your button.
Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
Just wrap a tag around all the HTML extract, for example
<a href="/categories/1">
<img alt="test1" class="img-responsive" src="/assets/photo.jpg" />
<div class="caption bg-orange">
<h2>
test1
</h2>
</div>
</a>
in my example my caption class has hover effects, that with pointer-events:none; you just will lose
wrapping the content will keep your hover effects and you can click in all the picture, div included, regards!
An easier way would be to inline the transparent background image using Data URIs as follows:
.click-through {
pointer-events: none;
background: url(data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7);
}
I think that you can consider changing your markup. If I am not wrong, you'd like to put an invisible layer above the document and your invisible markup may be preceding your document image (is this correct?).
Instead, I propose that you put the invisible right after the document image but changing the position to absolute.
Notice that you need a parent element to have position: relative and then you will be able to use this idea. Otherwise your absolute layer will be placed just in the top left corner.
An absolute position element is positioned relative to the first parent
element that has a position other than static.
If no such element is found, the containing block is html
Hope this helps. See here for more information about CSS positioning.
You can place an AP overlay like...
#overlay {
position: absolute;
top: -79px;
left: -60px;
height: 80px;
width: 380px;
z-index: 2;
background: url(fake.gif);
}
<div id="overlay"></div>
just put it over where you dont want ie cliked. Works in all.
This is not a precise answer for the question but may help in finding a workaround for it.
I had an image I was hiding on page load and displaying when waiting on an AJAX call then hiding again however...
I found the only way to display my image when loading the page then make it disappear and be able to click things where the image was located before hiding it was to put the image into a DIV, make the size of the DIV 10x10 pixels or small enough to prevent it causing an issue then hiding the containing div. This allowed the image to overflow the div while visible and when the div was hidden, only the divs area was affected by inability to click objects beneath and not the whole size of the image the DIV contained and was displaying.
I tried all the methods to hide the image including CSS display=none/block, opacity=0, hiding the image with hidden=true. All of them resulted in my image being hidden but the area where it was displayed to act like there was a cover over the stuff underneath so clicks and so on wouldn't act on the underlying objects. Once the image was inside a tiny DIV and I hid the tiny DIV, the entire area occupied by the image was clear and only the tiny area under the DIV I hid was affected but as I made it small enough (10x10 pixels), the issue was fixed (sort of).
I found this to be a dirty workaround for what should be a simple issue but I was not able to find any way to hide the object in its native format without a container. My object was in the form of etc. If anyone has a better way, please let me know.
I couldn't always use pointer-events: none in my scenario, because I wanted both the overlay and the underlying element(s) to be clickable / selectable.
The DOM structure looked like this:
<div id="outerElement">
<div id="canvas-wrapper">
<canvas id="overlay"></canvas>
</div>
<!-- Omitted: element(s) behind canvas that should still be selectable -->
</div>
(The outerElement, canvas-wrapper and canvas elements have the same size.)
To make the elements behind the canvas act normally (e.g. selectable, editable), I used the following code:
canvasWrapper.style.pointerEvents = 'none';
outerElement.addEventListener('mousedown', event => {
const clickedOnElementInCanvas = yourCheck // TODO: check if the event *would* click a canvas element.
if (!clickedOnElementInCanvas) {
// if necessary, add logic to deselect your canvas elements ...
wrapper.style.pointerEvents = 'none';
return true;
}
// Check if we emitted the event ourselves (avoid endless loop)
if (event.isTrusted) {
// Manually forward element to the canvas
const mouseEvent = new MouseEvent(event.type, event);
canvas.dispatchEvent(mouseEvent);
mouseEvent.stopPropagation();
}
return true;
});
Some canvas objects also came with input fields, so I had to allow keyboard events, too.
To do this, I had to update the pointerEvents property based on whether a canvas input field was currently focused or not:
onCanvasModified(canvas, () => {
const inputFieldInCanvasActive = // TODO: Check if an input field of the canvas is active.
wrapper.style.pointerEvents = inputFieldInCanvasActive ? 'auto' : 'none';
});
it doesn't work that way. the work around is to manually check the coordinates of the mouse click against the area occupied by each element.
area occupied by an element can found found by 1. getting the location of the element with respect to the top left of the page, and 2. the width and the height. a library like jQuery makes this pretty simple, although it can be done in plain js. adding an event handler for mousemove on the document object will provide continuous updates of the mouse position from the top and left of the page. deciding if the mouse is over any given object consists of checking if the mouse position is between the left, right, top and bottom edges of an element.
Nope, you can't click ‘through’ an element. You can get the co-ordinates of the click and try to work out what element was underneath the clicked element, but this is really tedious for browsers that don't have document.elementFromPoint. Then you still have to emulate the default action of clicking, which isn't necessarily trivial depending on what elements you have under there.
Since you've got a fully-transparent window area, you'll probably be better off implementing it as separate border elements around the outside, leaving the centre area free of obstruction so you can really just click straight through.
