I hope you have been in a position to spend time getting acquainted with the strategies we used to create tooltips in Half 1 of this fast two-parter. Collectively, we have been in a position to create a versatile tooltip sample that helps completely different instructions, positioning, and coloration with out including any complexity by any means to the HTML.
We leveraged the CSS border-image property based mostly on one other article I wrote whereas making use of intelligent clip-path methods to manage the tooltip’s tail. In case you haven’t checked out that article or the primary a part of this sequence, please do as a result of we’re leaping straight into issues immediately, and the context will likely be useful.
To date, we’ve checked out tooltip shapes with triangular tails with the choice to have rounded corners and gradient coloration. Positive, we have been in a position to do numerous issues however there are numerous different — and extra fascinating — shapes we will accomplish. That’s what we’re doing on this article. We’ll deal with instances the place a tooltip might have a border and completely different tail shapes, nonetheless with the least quantity of markup and most quantity of flexibility.
Earlier than we begin, I need to remind you that I’ve created an enormous assortment of 100 tooltip shapes. I mentioned in Half 1 that we might accomplish all of them in these two articles. We coated about half of them in Half 1, so let’s wrap issues up right here in Half 2.
The HTML
Identical as earlier than!
<div class=”tooltip”>Your textual content content material goes right here</div>
That’s the fantastic thing about what we’re making: We are able to create many, many alternative tooltips out of the identical single HTML component with out altering a factor.
Tooltips With Borders
Including a border to the tooltips we made in Half 1 is hard. We want the border to wrap round each the primary component and the tail in a steady trend in order that the mixed form is seamless. Let’s begin with the primary easy form we created in Half 1 utilizing solely two CSS properties:
.tooltip {
/* tail dimensions */
–b: 2em; /* base */
–h: 1em; /* peak*/
/* tail place */
–p: 50%;
border-image: fill 0 // var(–h)
conic-gradient(#CC333F 0 0);
clip-path:
polygon(0 100%, 0 0,100% 0, 100% 100%,
min(100%, var(–p) + var(–b) / 2) 100%,
var(–p) calc(100% + var(–h)),
max(0%, var(–p) – var(–b) / 2) 100%);
}
Right here’s the demo. You need to use the vary slider to see how versatile it’s to alter the tail place by updating the –p variable.
This most likely will not be {that a} massive deal normally. A couple of pixels aren’t a obvious visible challenge, however you may determine whether or not or not it meets your wants. Me? I’m a perfectionist, so let’s attempt to repair this minor element even when the code will get a bit extra complicated.
We have to do some math that requires trigonometric features. Particularly, we have to change among the variables as a result of we can not get what we would like with the present setup. As an alternative of utilizing the base variable for the tail’s dimensions, I’ll think about an angle. The second variable that controls the peak will stay unchanged.
The connection between the bottom (–b) and the angle (–a) is the same as B = 2*H*tan(A/2). We are able to use this to replace our present code:
.tooltip {
/* tail dimensions */
–a: 90deg; /* angle */
–h: 1em; /* peak */
–p: 50%; /* place */
–t: 5px; /* border thickness */
border-image: fill 0 // var(–h)
conic-gradient(#5e412f 0 0); /* the border shade */
clip-path:
polygon(0 100%, 0 0, 100% 0, 100% 100%,
min(100%, var(–p) + var(–h) * tan(var(–a) / 2)) 100%,
var(–p) calc(100% + var(–h)),
max(0%, var(–p) – var(–h) * tan(var(–a) / 2)) 100%);
place: relative;
z-index: 0;
}
.tooltip:earlier than {
content material: “”;
place: absolute;
inset: var(–t) 0;
border-image: fill 0 / 0 var(–t) / var(–h) 0
conic-gradient(#CC333F 0 0); /* the background shade */
clip-path: inherit;
}
Nothing drastic has modified. We launched a brand new variable to manage the border thickness (–t) and up to date the clip-path property with the brand new variables that outline the tail’s dimensions.
Now, all of the work will likely be performed on the pseudo-element’s clip-path property. It should now not inherit the primary component’s worth, nevertheless it does want a brand new worth to get the proper border thickness across the tail. I need to keep away from getting deep into the complicated math behind all of this, so right here is the implementation:
polygon(0 100%, 0 0, 100% 0, 100% 100%,
min(100% – var(–t), var(–p) + var(–h)tan(var(–a)/2) – var(–t)tan(45deg – var(–a) / 4)) 100%,
var(–p) calc(100% + var(–h) + var(–t)(1 – 1/sin(var(–a)/2))),
max(var(–t), var(–p) – var(–h)tan(var(–a)/2) + var(–t)*tan(45deg – var(–a)/4)) 100%);
It seems complicated as a result of it’s! You don’t actually need to know the formulation since all it’s a must to do is regulate just a few variables to manage all the things.
Now, lastly, our tooltip is ideal. Right here is an interactive demo the place you may regulate the place and the thickness. Don’t overlook to additionally play with the dimension of the tail as effectively.
Let’s transfer on to the rounded corners. We are able to merely use the code we created within the earlier article. We duplicate the form utilizing a pseudo-element and make just a few changes for good alignment and an accurate border thickness.
The explanation I’m not going into particulars for this one is to make the purpose that you just don’t have to recollect all the assorted use instances and code snippets by coronary heart. The objective is to know the precise ideas we’re utilizing to construct the tooltips, like working with border-image, clip-path(), gradients, and math features.
I can’t even keep in mind many of the code I write after it’s performed, nevertheless it’s no challenge since all I’ve to do is copy and paste then regulate just a few variables to get the form I would like. That’s the good thing about leveraging fashionable CSS options — they deal with loads of the work for us.
Border-Solely Tooltips
I’d love to do yet another train with you, this time making a tooltip with no fill however nonetheless with a full border across the complete form. To date, we’ve been in a position to reuse loads of the code we put collectively in Half 1, however we’re going to want new methods to drag this one off.
The objective is to ascertain a clear background whereas sustaining the border. We’ll begin with out rounded corners for the second.
See how we’re going to be working with gradients once more? I might have used a single shade to supply a strong, single-color border, however I put a tough cease in there to reveal the concept. We’ll be capable to create much more variations, because of this little element, like utilizing a number of colours, completely different shade stops, and even several types of gradients.
You’ll see that the code seems pretty easy:
/* tail dimension */
–a: 90deg; /* angle */
–h: 1em; /* peak */
–p: 50%; /* tail place */
–b: 7px; /* border thickness */
place: relative;
}
.tooltip:earlier than {
content material: “”;
place: absolute;
inset: 0 0 calc(-1*var(–h));
clip-path: polygon( … ); /* and so forth. */
background: linear-gradient(45deg, #cc333f 50%, #79bd9a 0); /* colours */
}
We’re utilizing pseudo component once more, this time with a clip-path to ascertain the form. From there, we set a linear-gradient() on the background.
I mentioned the code “seems” very easy. Structurally, sure. However I purposely put a placeholder clip-path worth as a result of that’s the sophisticated half. We wanted to make use of a 16-point polygon and math formulation, which actually gave me massive complications.
That’s why I flip to my on-line generator normally. In any case, what’s the purpose of everybody spending hours attempting to suss out which formulation to make use of if math isn’t your factor? Might as effectively use the instruments which are accessible to you! However be aware how a lot better it feels to make use of these instruments while you perceive the ideas which are working below the hood.
OK, let’s deal with rounded corners:
For this one, we’re going to depend on not one, however two pseudo-elements, :earlier than and :after. One will create the rounded form, and the opposite will function the tail.
The above determine illustrates the method for creating the rounded half with the :earlier than pseudo-element. We first begin with a easy rectangular form that’s full of a conic gradient containing three colours. Then, we masks the form in order that the internal space is clear. After that, we use a clip-path to chop out a small a part of the underside edge to order house for the tail we’ll make with the :after pseudo-element.
.tooltip {
/* tail dimension */
–a: 90deg; /* angle */
–h: 1em; /* peak */
–p: 50%; /* tail place */
–b: 7px; /* border thickness */
–r: 1.2em; /* the radius */
place: relative;
z-index: 0;
}
/* each pseudo-elements */
.tooltip:earlier than,
.tooltip:after {
content material: “”;
background: conic-gradient(#4ECDC4 33%, #FA2A00 0 66%, #cf9d38 0); /* the coloration */
inset: 0;
place: absolute;
z-index: -1;
}
/* the rounded rectangle */
.tooltip:earlier than {
background-size: 100% calc(100% + var(–h));
clip-path: polygon( … );
masks: linear-gradient(#000 0 0) content-box, linear-gradient(#000 0 0);
mask-composite: exclude;
padding: var(–b);
}
/* the tail */
.tooltip:after {
content material: “”;
place: absolute;
backside: calc(-1 * var(–h));
clip-path: polygon( … );
}
As soon as once more, the construction will not be all that complicated and the clip-path worth is the robust half. As I mentioned earlier, there’s actually no must get deep into an evidence on it once we can use the factors from a web based generator to get the precise form we would like.
The brand new piece that’s launched on this code is the masks property. It makes use of the identical method we coated in but one other Smashing article I wrote. Please learn that for the total context of how masks and mask-composite work collectively to trim the clear space. That’s the primary a part of your homework after ending this text.
Enjoyable Tail Shapes
We’ve coated just about each single one of many tooltips accessible in my assortment. The one ones we now have not particularly touched use quite a lot of completely different shapes for the tooltip’s tail.
All the tooltips we created on this sequence used a easy triangle-shaped tail, which is a regular tooltip sample. Positive, we discovered how you can change its dimensions and place, however what if we would like a unique type of tooltip? Perhaps we would like one thing fancier or one thing that appears extra like a speech or thought bubble.
If the rounded corners within the final part are the primary a part of your homework, then the subsequent half is to attempt making these tail variations your self utilizing what we now have discovered collectively in these two articles. You may at all times discover the code over at my assortment for reference and hints. And, go away a remark right here you probably have any further questions — I’m pleased to assist!
Conclusion
I hope you loved this little sequence as a result of I positive had a blast writing it. I imply, take a look at the entire issues we completed in a comparatively brief quantity of house: easy rectangular tooltips, rounded corners, completely different tail positions, strong and gradient backgrounds, a bunch of border choices, and eventually, customized shapes for the tail.
I most likely went too far with what number of forms of tooltips we might make — there are 100 in whole while you rely them up! However it goes to point out simply what number of prospects there are, even once we’re at all times utilizing the identical single component within the HTML.
And, it’s nice observe to think about the entire completely different use instances and conditions you could run into while you want a tooltip element. Maintain these in your again pocket for while you want them, and use my assortment as a reference, for inspiration, or as a place to begin in your personal work!
