Tooltips do not appear on mobile phones and other touch devices. Remember, these little information bubbles only appear when a mouse hovers over them. Devices like mobile phones and tablets that rely on touch do not typically have mice attached.
Tooltips present an accessibility challenge. People who rely on screen readers eg, the blind or who can only use the keyboard to navigate eg, the blind and those with some sort of muscle impairment will most likely never get to know what your tooltip contains. In fact, they probably won't even know there was a tooltip in the first place. Even among those who can see, not everyone knows that they can get more information by hovering their mice over a piece of text or picture or whatever.
It's not obvious to a person reading a page that they should scan for tooltips, even if that person is an experienced computer user. The argument is that if you think your users need more information about something, it's generally best to put it in plain sight by default. For example, the Free Mobile-Friendly Layout Wizard does this by placing the explanation for each option in Step 2 directly below it, as indeed do all the other wizards. The caveats above notwithstanding, the rest of the article descibes 2 of probably many ways of displaying tooltips.
But bear in mind the fundamental problems about tooltips given here. Use them only for optional information which your users can function without. The easiest and most compatible way of popping up one of those contextual information tips is to use the method provided by the HTML standards, the title attribute. If you want to see a demo of this code, just scroll up the page to the second paragraph of this article, and hover your mouse over the link there.
The standards specify that title is a global attribute, which means that you can add it to any HTML element, just like you can an id or a class. That is, although I used it on a link in my example, you can add it to anything, even a paragraph or an entire column enclosed in a DIV block.
Incidentally, the HTML standards do not require that browsers present the content of the title attribute as a tooltip bubble. Screen readers used by the blind , however, generally ignore the title attribute, and people relying on such software will not even know that a tooltip is available. Another way is to use CSS to display the tooltip.
This method gives you more flexibility in what the tooltip bubble looks like, and even allows you to use images if you wish. It is, however, even less accessible than the title method, if such a thing were possible.
That is, people who need screen readers and other accessibility tools will probably have no hope at all of knowing that your tooltip exists, let alone finding out what it says. Here's the HTML for the same tooltip given earlier, but implemented using the content property and the ::after pseudo-element. Move your mouse over it to see it in action.
This method of displaying a tooltip uses many features eg, the content property, the ::after pseudo-element, the use of position for ::after , etc that rely on your users having a modern browser. If they use an older browser, the tooltip will not be displayed correctly, if at all. It uses elements like div, paragraph and many others also.
Whenever a mouse gets hovers on that specific attribute, it will show text or other information known as a tooltip. It can be displayed at right, left, top or bottom at any position of the text. This is as follows:. One can also be able to display an arrowed tooltip to the element by using this tooltip feature defined in it. HTML tooltip helps to open the linked webpage, related documents or image also.
We can display that using tooltip is displaying tooltip with fade in just like an animation effect. We can do this by using code as follows:. We can do the most important thing by using a tooltip to open a modal box by clicking a single tooltip. This type of code is mostly used whenever needed to open some kind of forms or other details by using a simple link. This is treated as the simplest way to open modal with minimum code. This example illustrates that we can use tooltip on some links as well as for images also.
So whenever the user hovers the mouse on it, this will display information or clickable link to open another webpage or document. Whenever we want to display a popup on hover or click on specific elements, then a tooltip is the best option to handle this thing easily. Note: See examples below on how to position the tooltip. The tooltiptext class holds the actual tooltip text. It is hidden by default, and will be visible on hover see below.
We have also added some basic styles to it: px width, black background color, white text color, centered text, and 5px top and bottom padding. The CSS border-radius property is used to add rounded corners to the tooltip text. Also note that toppx is used to place it in the middle of its container element. We use the number 5 because the tooltip text has a top and bottom padding of 5px. If you increase its padding, also increase the value of the top property to ensure that it stays in the middle if this is something you want.
The same applies if you want the tooltip placed to the left. If you want the tooltip to appear on top or on the bottom, see examples below. Note that we use the margin-left property with a value of minus 60 pixels. To create an arrow that should appear from a specific side of the tooltip, add "empty" content after tooltip, with the pseudo-element class ::after together with the content property.
The arrow itself is created using borders. This will make the tooltip look like a speech bubble. Note: The border-width property specifies the size of the arrow. If you change this, also change the margin-left value to the same. This will keep the arrow centered.
