Please note: I have already tried the solution listed here which does not serve my purposes as it still draws a box around the image
Update: I have taken a further look into this and found that one solution is to draw an SVG of the image in question and make this the button so that there is not such a large box surrounding the image. I would prefer not to do this as I have many assets but would this be the only solution?
I am trying to place a button on my website but make it so that the clickable area is exactly the image and nothing else. I have been trying to find solutions for this but perhaps I am not searching the correct terms.
At present, I am using Bootstrap to create a button for a carousel. This works fine but the issue I am having is the square border around the button itself which will cause a problem as I put more buttons on the page that are closely placed together.
I would like the clickable area to be restricted strictly to the png itself, which includes the white border seen on the image linked above.
My code at present looks as follows.
HTML:
<div class='background'></div>
<div class="map">
<img id='mainMap' src='assets/maps/map.png' alt='map'>
<!-- Modal's toggle button has data that's used to determine what content to use -->
<!-- Bridge icons -->
<button type="button" class="btn btn-primary-outline-btn bridge-btn" id='bridge1' data-toggle="modal" data-target="#exampleModal"><img class="bridge_icon" src="assets/icons/bridge1.png" alt="image"></button>
</div>
CSS:
.camera_icon, .video_icon{
width: 30px;
height: 30px;
}
.bridge_icon {
width: 150px;
height: auto;
margin: 0px;
padding: 0px;
}
#bridge1 {
top: 3%;
left: 10%;
position: inherit;
}
/* Buttons */
.btn, .btn-outline-primary, .video-btn {
background-color: transparent;
border-color: #ccc;
padding: 0px;
box-shadow: none;
}
.btn:focus,.btn:active {
outline: none !important;
box-shadow: none;
}
.bridge-btn {
border-color: hotpink;
}
.btn-outline-primary:hover, .video-btn:hover{
background-color: #e4dbef;
border-color: #ccc;
}
.btn-outline-primary:focus, .video-btn:focus{
background-color: #e4dbef;
outline: none;
border-color: #ccc;
}
.btn:focus, .btn:active:focus, .btn.active:focus { outline: none; ! important; outline-style: none; }
Any help you could provide would be very useful.
Thank you.
If I understand correctly the button has a border you don't want? If that is the case try changing btn-primary-outline-btn to btn-transparent-outline-btn
So my cursor is still the default one even though I've changed it to pointer. As I was taking screenshots to post here I noticed if I hovered on the link and hit CMD it would change to a pointer but it would remain like that everywhere on the page unless I hit CMD again. My second problem is turning off the default shadow on an text input field. Ive tried box-shadow: none; but it didn't work. Im on a mac using safari 9.0.3Default shadow on input element
form {
width: 100%;
input[type=text]{
border-radius: 0.5em;
height: 1.5vw;
font-size: $fntSize;
width: 12.7%;
position: absolute;
top: 10.35vw;
left: 68.3vw;
box-shadow: none;
cursor: text;
}
input[type=image]{
position: absolute;
top: 10.8vw;
left: 80.1vw;
height: 0.8vw;
cursor: pointer;
Solving the issue with the cursor would be a lot easier with a jsfiddle that replicates the error on your end.
In terms of the default styling on the input, that's actually a border style not a box-shadow. The input defaults to border-style: inset so you just need to set your desired properties in its place. E.g. border: 1px solid #ccc or border-style: solid at a minimum.
I have a code like this
<div style="position: absolute; margin-left: -22px; margin-top: -22px; left: 502px; top: 379px; z-index: 380; display: block;" class="maptimize_marker_0 f st">1<span class="pinlabel">1B 100E</span></div>
I also have CSS for pinlabel
.pinlabel{
display: none;
position: absolute;
background-color: #3774d5;
height: 16px;
width: 200px;
color: white;
top: 0px;
left: 1px;
font-size: 10px !important;
border-radius: 10px;
border: white 2px solid;}
.maptimize_marker_0:hover span.pinlabel {display:block;}
But I cant get the Hover state work. If to Force hover state in developer tool in chrome everything works fine, but not working when mouse is over... What am I doing wrong? Also I want to put span Under the div, but the span is always on top and covers the div background picture... Please help!
I'm not sure what your problem is, on http://jsfiddle.net/abrunet/Bb9T3/, I copy paste your code and the hover is working..
Last, your span does not have a z-index specified. You might chose one, lower than the divs one and an other higher for the hover case.
You should also try to separate your style in a different sheet to keep your code clean.
Let me know if I misunderstood your question.
I'm not a pro in CSS but I'm trying to learn.
I have this little sandbox going on:
It's basically a bunch of icons with some extra detail that is displayed once you hover over the icon.
I've been playing around with CSS trying to make this work but I get erratic behaviour so far. Code is here
I wonder if I could somehow immitate a rich tooltip so it opens up when the icon is hovered over, and without changing the position of the other icons.
Any creative idea, including a change in basic design, will be gladly accepted.
My goal is to achieve this using CSS3 Transitions so minimal to no JavaScript is ideal.
Thanks!
Maybe you could use hint.css, its a pure css tooltip
http://kushagragour.in/lab/hint/
I think you need tutorial to view Create CSS3 Tooltip and the main code is
<a title="Create Simple Tooltip Using CSS3" class="tooltip">Some Sample CSS3 Tooltip</a>
.tooltip
{
display: inline;
position: relative;
}
.tooltip:hover:after
{
background: #333;
background: rgba(0,0,0,.8);
border-radius: 5px;
bottom: 26px;
color: #fff;
content: attr(title);
left: 20%;
padding: 5px 15px;
position: absolute;
z-index: 98;
width: 220px;
}
.tooltip:hover:before
{
border: solid;
border-color: #333 transparent;
border-width: 6px 6px 0 6px;
bottom: 20px;
content: "";
left: 50%;
position: absolute;
z-index: 99;
}
I currently set the title attribute of some HTML if I want to provide more information:
<p>An <span class="more_info" title="also called an underscore">underline</span> character is used here</p>
Then in CSS:
.more_info {
border-bottom: 1px dotted;
}
Works very nice, visual indicator to move the mouse over and then a little popup with more information. But on mobile browsers, I don't get that tooltip. title attributes don't seem to have an effect. What's the proper way to give more information on a piece of text in a mobile browser? Same as above but use Javascript to listen for a click and then display a tooltip-looking dialog? Is there any native mechanism?
You can fake the title tooltip behavior with Javascript. When you click/tab on an element with a title attribute, a child element with the title text will be appended. Click again and it gets removed.
Javascript (done with jQuery):
$("span[title]").click(function () {
var $title = $(this).find(".title");
if (!$title.length) {
$(this).append('<span class="title">' + $(this).attr("title") + '</span>');
} else {
$title.remove();
}
});
CSS:
.more_info {
border-bottom: 1px dotted;
position: relative;
}
.more_info .title {
position: absolute;
top: 20px;
background: silver;
padding: 4px;
left: 0;
white-space: nowrap;
}

Here is a CSS only solution. (Similar to #Jamie Pate 's answer, but without the JavaScript.)
We can use the pseudo class :hover, but I'm not sure all mobile browsers apply these styles when the element is tapped. I'm using pseudo class :focus because I'm guessing it's safer. However, when using pseudo class :focus we need to add tabindex="0" to elements that don't have a focus state intrinsically.
I'm using 2 #media queries to ensure all mobile devices are targeted. The (pointer: coarse) query will target any device that the primary input method is something "coarse", like a finger. And the (hover: none) query will target any device that the primary pointing system can't hover.
This snippet is all that's needed:
#media (pointer: coarse), (hover: none) {
[title] {
position: relative;
display: inline-flex;
justify-content: center;
}
[title]:focus::after {
content: attr(title);
position: absolute;
top: 90%;
color: #000;
background-color: #fff;
border: 1px solid;
width: fit-content;
padding: 3px;
}
}
/*Semantic Styling*/
body {
display: grid;
place-items: center;
text-align: center;
height: 100vh;
}
a {
height: 40px;
width: 200px;
background: #fa4766;
color: #fff;
text-decoration: none;
padding: 10px;
box-sizing: border-box;
border-radius: 10px;
}
/*Functional Styling*/
#media (pointer: coarse), (hover: none) {
[title] {
position: relative;
display: flex;
justify-content: center;
}
[title]:focus::after {
content: attr(title);
position: absolute;
top: 90%;
color: #000;
background-color: #fff;
border: 1px solid;
width: fit-content;
padding: 3px;
}
}
<a title="this is the Title text" tabindex="0">Tag with Title</a>
Obviously, you'll need to open this on a mobile device to test it.
Here is a Pen with the same code.
Given that a lot of people nowadays (2015) use mobile browsers, and title still hasn't found a form of exposure in mobile browsers, maybe it's time to deprecate reliance upon title for meaningful information.
It should never be used for critical information, but it is now becoming dubious for useful information, because if that information is useful and cannot be shown to half the users, then another way of showing it to almost all users needs to be found.
For static pages, perhaps some visible text near to the relevant control, even as fine print. For server-generated pages, browser sniffing could provide that only for mobile browsers. On the client side, javascript could be used to trap the focus event, via bubbling, to show the extra text next to the currently focussed element. That would minimise the screen space taken up, but would not necessarily be of much use, since, in a lot of instances, bringing focus to a control can only be done in a way that immediately activates its action, bypassing the ability to find out about it before using it!
Over all though, it appears that the difficulties of showing the title attribute on mobile devices, may lead to its demise, mostly due to needing an alternative that is more universal. That is a pity, because mobiles could use a way to show such extra info on-demand, without taking up the limited screen space.
It seems strange that the w3c and mobile browser makers did not do anything about this issue a long time ago. At least they could have displayed the title text on top of the menu that appears when a long press on a control is made.
Personally, I wish it was placed at the top of a right-click/long-touch menu, as it won't timeout, and would be available on all browsers.
The other alternative is to construct footnotes, so an [n] type superscript is put next to the element/text needing more info, linking to explanatory text in a list at the bottom of the page. Each of those can have a similar [n] type link back to the original text/element. That way, it keeps the display uncluttered, but provides easy bidirectional swapping in a simple way. Sometimes, old print media ways, with a little hyperlink help, are best.
The title attribute has been hijacked by some browsers to provide help text for the pattern attribute, in that its text pops up if the pattern doesn't match the text in the input element. Typically, it is to provide examples of the right format.
Slightly more elaborated version of flavaflo's answer:
Uses pre-defined div as pop-up that can hold HTML, rather than reading from a title attribute
Opens/closes on rollover if mouse is used
Opens on click (touch screen) and closes on click on the open pop-up or anywhere else on the document.
HTML:
<span class="more_info">Main Text<div class="popup">Pop-up text can use <b>HTML</b><div></span>
CSS:
.more_info {
border-bottom: 1px dotted #000;
position: relative;
cursor: pointer;
}
.more_info .popup {
position: absolute;
top: 15px; /*must overlap parent element otherwise pop-up doesn't stay open when rolloing over '*/
background: #fff;
border: 1px solid #ccc;
padding: 8px;
left: 0;
max-width: 240px;
min-width: 180px;
z-index: 100;
display: none;
}
JavaScript / jQuery:
$(document).ready(function () {
//init pop-ups
$(".popup").attr("data-close", false);
//click on pop-up opener
//pop-up is expected to be a child of opener
$(".more_info").click(function () {
var $title = $(this).find(".popup");
//open if not marked for closing
if ($title.attr("data-close") === "false") {
$title.show();
}
//reset popup
$title.attr("data-close", false);
});
//mark pop-up for closing if clicked on
//close is initiated by document.mouseup,
//marker will stop opener from re-opening it
$(".popup").click(function () {
$(this).attr("data-close",true);
});
//hide all pop-ups
$(document).mouseup(function () {
$(".popup").hide();
});
//show on rollover if mouse is used
$(".more_info").mouseenter(function () {
var $title = $(this).find(".popup");
$title.show();
});
//hide on roll-out
$(".more_info").mouseleave(function () {
var $title = $(this).find(".popup");
$title.hide();
});
});

As #cimmanon mentioned: span[title]:hover:after { content: attr(title) } gives you a rudimentary tooltip on touch screen devices. Unfortunately this has problems where the default ui behavior on touch screen devices is to select the text when any non-link/uicontrol is pressed.
To solve the selection problem you can add span[title] > * { user-select: none} span[title]:hover > * { user-select: auto }
A full solution may use some other techniques:
Add position: absolute background, border, box-shadow etc to make it look like a tooltip.
Add the class touched to body (via js) when the user uses any touch event.
Then you can do body.touched [title]:hover ... without affecting desktop users
document.body.addEventListener('touchstart', function() {
document.body.classList.add('touched');
});
[title] {
border-bottom: 1px dashed rgba(0, 0, 0, 0.2);
border-radius:2px;
position: relative;
}
body.touched [title] > * {
user-select: none;
}
body.touched [title]:hover > * {
user-select: auto
}
body.touched [title]:hover:after {
position: absolute;
top: 100%;
right: -10%;
content: attr(title);
border: 1px solid rgba(0, 0, 0, 0.2);
background-color: white;
box-shadow: 1px 1px 3px;
padding: 0.3em;
z-index: 1;
}
<div>Some text where a portion has a <span title="here's your tooltip">tooltip</span></div>
Depending on how much information you want to give the user, a modal dialogue box might be an elegant solution.
Specifically, you could try the qTip jQuery plugin, which has a modal mode fired on $.click():
The title attribute is not supported in any mobile browsers **in a way that it would show the tooltip the same as to desktop mouse users** *(the attribute itself is ofcourse supported in the markup)*.
It's only basically for desktop users with a mouse, keyboard only users can't use it either, or screenreaders.
You can achieve almost similar with javascript as you said.
I was searching for an easy CSS only solution, and this is really the most easy one I found:
<link rel="stylesheet" href="https://unpkg.com/balloon-css/balloon.min.css">
<span aria-label="Whats up!" data-balloon-pos="up">Hover me!</span>
Working example: https://jsfiddle.net/5pcjbnwg/
If you want to customize the tooltip, you find more info here:
https://kazzkiq.github.io/balloon.css/
To avoid using JavaScript, I used this CSS-only tooltip:
http://www.menucool.com/tooltip/css-tooltip
It works great in Mobile and Desktop, and you can customize the styles.
Thanks to #flavaflo for their answer. This works in most cases but if there is more than one title to lookup in the same paragraph, and one opens over the link to another, the unopened link shows through the first. This can be solved by dynamically changing the z-index of the title that has "popped up":
$("span[title]").click(function () {
var $title = $(this).find(".title");
if (!$title.length) {
$(this).append('<span class="title">' + $(this).attr("title") + '</span>');
$(this).css('z-index', 2);
} else {
$title.remove();
$(this).css('z-index', 0);
}
});
Also, you can make both the hover over display and the click display multiline by adding
(linefeed) to the title='' attribute, and then convert that to <br /> for the html click display:
$(this).append('<span class="title">' + $(this).attr("title").replace(/\\n/g, '<br />') + '</span>');
Extremely late to the party but for future visitors, here is a tweak of #Flavaflo's answer to fade the "tooltip" in and out
JQuery:
$(".more_info").click(function () {
var $title = $(this).find(".title");
if (!$title.length) {
$(this).append('<span class="title">' + $(this).attr("title") + '</span>');
} else {
$($title).fadeOut(250, function() {
$title.remove();
});
}
});
CSS:
.more_info {
border-bottom: 1px dotted;
position: relative;
}
.more_info .title {
position: absolute;
top: 20px;
background: green;
padding: 4px;
left: 0;
color: white;
white-space: nowrap;
border-radius:3px;
animation: fadeIn linear 0.15s;
}
#keyframes fadeIn {
0% {opacity:0;}
100% {opacity:1;}
}

I know this is an old question, but i have found a CSS solution that works on mobile too, it doesn't use title at all and it's easy to implement, explained here:
https://www.w3schools.com/css/css_tooltip.asp
Explanation:
On mobile, with the touchscreen,the first input acts as css hover, so it works like a toggle tooltip when you press on it.
Code example:
.tooltip {
position: relative;
display: inline-block;
border-bottom: 2px dotted #666;
}
.tooltip .tooltiptext {
visibility: hidden;
width: 15em;
background-color: #555;
color: #fff;
text-align: center;
border-radius: 6px;
position: absolute;
z-index: 1;
bottom: 125%;
left: 50%;
margin-left: -8em;
opacity: 0;
transition: opacity 0.3s;
padding: 0.5em;
}
.tooltip .tooltiptext::after {
content: "";
position: absolute;
top: 100%;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: #555 transparent transparent transparent;
}
.tooltip:hover .tooltiptext {
visibility: visible;
opacity: 1;
}
<div class="tooltip">Hover over me
<span class="tooltiptext">Tooltip text</span>
</div>
