I'm hoping that there's a way to make an image that is stacked underneath another image be clickable while the front image is not.
The front image is a semi-transparent png (think of a watermark or similar). The image behind is linked to an action. (This is not exactly what it does, so please no off-topic comments about this being a poor way to watermark... I know that!)
However if the image is in front the action will not ever be triggered, as the front image is 'blocking' the click.
Some code would be beneficial but it sounds like you need
pointer-events:none
MDN Reference
In addition to indicating that the element is not the target of mouse events, the value none instructs the mouse event to go "through" the element and target whatever is "underneath" that element instead.
Support however (foot of reference page) is good except for IE which is 11+

I’ve got a tricky issue going on that I can’t seem to figure out. It’s a lot of different files so let’s start without any code or file docs added.
So I’ve got a SVG image with a lot of square paths all over it. I placed an Square image over one of the square paths in Inkscape. Then I embedded the SVG file into HTML, where I think added a link to that path w/ image. I was having no issues adding the links or anything and it was working just fine, but now it seems as if the image is canceling out the link. Before the link worked just fine but when the image loads over the square it acts as if it’s covering the link. Before the image is fully loaded into the browser the link works and is accessible. But once the image loads on top of that path with the link it covers it and doesn’t work anymore.
Is this common and am I dumb? Seems like I’m just missing something here. Need to basically add the image somehow without it covering the linked path underneath.
Please help!!!
You have probably already found the answer. In SVG all elements are drawn on top of all previous (so the order of the elements in the file matters).
If one element completely covers the other below him then it will essentially block its interactive events. The solution is to notify CSS engine to drop through any pointer events for this element (or elements with same style) using
.nopointer { pointer-events: none }
in the section of the SVG or in the wrapped HTML CSS style section.
For the links to work for SVG elements - since you can add a link attribute to SVG elements as well, e.g. if you would have SVG IMAGE elements overlaid on your rectangles - don't forget to add the XLink namespace in the SVG root element declaration.
I want to make an iframe of this https://rustypipe.deepraven.co/video/8ci2hj7CSHI/ (which is a random youtube video). However I do not want for the search bar or the rustypipe logo to be seen. I want the iframe to be only focused on the video.
How do I achieve this with html and css?
This is what I mean:
I do not want this.
I want this.
UPDATE: I need it to be an iframe.
Add a <p> tag right above the <a> tag. Set the background to white, position absolute, and give it an appropriate width and height and there ya have it:
After, you can also use after css transform properties like scale to get to the size you want. Let me know if you have any questions!
Here is a screenshot of the additional tag in the HTML and the classes set on it
Let me know if that makes sense. We're basically just taking a white strip and putting it over the part we don't want.
Don't use my exact measurements, i'm sure you will find the perfect ones for yours :)
Unless you really need the iframe, you could embed only the video (copy the <video> tag from the website).
Most Browsers let you right click on the DOM Node in the inspector (press F12 to get there) and copy the HTML.
Inside the <video> tag, there are links to the video source, so you don't have to download the video.
If you do need the iframe, you will probably have to render the whole content (not a big deal for your case) and zoom into the part, that you want to see.
Here is a thread about that. The bottom comment also mentions this blog post.
On succession of a previous question I tried to find out if the next thing is possible:
Take you have a render, like a soccer player with a transparant background. You add this render to your html & css. The transparant parts are now part of the image 'box'; you can't click on links under the image transparant parts, but you can see them.
Is it possible to make these links clickable? Thus having the image as highest z-index, but still have the links clickable and working.
(the links have a lower z-index because their background then stops under the image, giving a nicer design)
(Or said otherwise: have a .png image with a transparant background not shown as a box, but as only the colored pixels. Preferable only in html/css)
I think it is not possible, to be honest. If you do not yet understand my question, maybe my previous will help you:
need help fixing the link's clickable area
You can use pointer-events to make an event (click in this case) bubble through to the layer below.
No, it's not possible from what I'm aware of. However you can do similar things to what you want that may be useful:
Turn an area into a link using <map>
Use pointer-events:none so that clicks are ignored on the top element
IE 10 provides the non-standard msElementsFromPoint method that allows you to "peek below" an element; you can do that inside the click handler and determine if the click point overlaps an anchor. If it does, triggering that element's click event would do what needs to be done.
Unfortunately I am not aware of similar functionality for other browsers or earlier versions of IE.
This works fine on my computer but im wondering if its a good idea in terms of accessibility, etc.
I have a page of product listings, and I want each listing to link to a product page. The listing is made up of an image and a few photographs of text.
I want the entire listing area to be a link, including white space. So rather than make the images and text links individually, ive put the entire div in a link.
As I said, this is working fine on my computer, but is a good idea for a production site?
Thanks
If it's like a grid or something, and you give a visual cue when the user moves the mouse over the row (background color changing etc) along with the cursor becoming a hand, it should be fine if you use the whitespace as part of your link.
If you want me in your website's audience, I would prefer if you wouldn't. When switching between windows, clicking in the window area is the quickest way to switch focus between windows. If like 80% of your window is really a link, I would find that annoying. I think I am not the only one.
The way it sounds there is also plenty of area which you can make behave like a link, such as the image, and the text in the grid. If that would be clickable, that would be big enough a target to hit.
Also imagine your app being used on a touch screen. These sometimes imsinterpret drag (scroll/zoom) and tick gestures. Which is annoying if everything responds to clicks.
Look at the right-side video links on YouTube. These are block-layout spans wrapped in a tags. (Not that just because Google does it means it's a good idea, but...)
If the area has a :hover color (as these do), then it should be clear enough to the user that this is an action item.
Syntactically it's invalid, you cannot put block elements (div, p, table) inside of inline elements (span, a, strong, em).
When you touch an element, such as an edit box, in a web page on the iPad, it turns gray while you are touching it.
I have a table wrapped by a floating div. Instead of an individual data element or row going gray, the whole table (or its wrapping div) goes gray when a data element is touched. (The function of this table is an autocomplete pop-up)
Elsewhere in the site, I have a table in which only the touched data element goes gray.
I wondered if anyone could direct me to an explanation of the logic behind this graying on touch, so that we can code our table to give the desired behavior. Ideally, we'd like the row to highlight when it is touched.
In the alternative, if we could turn off this graying behaviour, that would be another option. We could then code the highlighting ourselves. Is there a way to turn off this behavior for particular html elements?
Thanks.
This author suggests a solution to remove the highlighting:
If for whatever reason you don't want some elements of your web site or application to be highlighted, simply add the following CSS rule to the corresponding elements.
-webkit-tap-highlight-color: rgba(0,0,0,0);
It won't disable the highlighting, but it will make it invisible (an opacity of zero).
I have not tested this, however.
I have discovered something about the "logic" behind the graying behavior. It seems that elements that have handlers such as onclick, onmousedown etc. exhibit the behavior and those without such handlers don't. A (somewhat tedious) workaround for us is to change the code of the autocomplete so that each row has its own onmousedown etc. handler rather than the wrapping div taking care of this.
Try styling the wrapper div with select:none;
That should turn it off, and then you could code the highlight onfocus yourself.
Most browsers actually do this, but it's a bit more noticeable on the iPad and other Apple touch products. It's really for usability purposes, so I would only recommend disabling it if it is causing problems like the one you mentioned. It serves to help the user know what they are clicking, and gives them a chance to move their finger away if they are on the wrong thing.
