On this textual content, we’ll check out some easy methods to vogue the HTML
It’s helpful to have a easy disclosure think about HTML that doesn’t require JavaScript, nonetheless the default styling of the
The desk of contents beneath is an event of the
Desk of Contents
Introducing the main points Ingredient
Correct proper right here’s the fundamental code for the
particulars>

Primarily any HTML content material materials supplies is more likely to be positioned contained inside the
difficulty gives the speedy for the actual individual to click on on on on the problem to disclose additional content material materials supplies, and it should be the primary teen of the
difficulty.
Correct proper right here’s a preserve event of this code:
Click on on on me!
Peekaboo! Correct proper right here’s some hidden content material materials supplies!
Let’s check out all of the methods we’ll use CSS to boost the seems to be like of our
Background Colours, Borders and Padding
A terribly easy decision to reinforce the look of the
Along with a border
As confirmed all through the desk of contents above, a easy border can accomplish that quite a bit to boost and outline the
particulars {
padding: 10px;
border: 5px sturdy #f7f7f7;
border-radius: 3px;
}
That’s the easy code we’ve used above to vogue our ToC.
Along with some background coloration
Let’s add a background coloration to our
particulars {
padding: 10px;
background-color: #e4eaef;
border-radius: 5px;
}
The result’s confirmed all through the Pen beneath.
The background coloration offers the problem higher definition, and the padding helps to create some dwelling inside it.
We’re ready to furthermore give a selected background coloration to the
abstract {
background-color: #2196F3;
coloration: white;
padding: 10px;
}
Uncover that altering the textual content material materials coloration of the
difficulty merely as markers (akin to bullets) are hooked as a lot as tips objects. We’ll see beneath easy methods to vogue them individually.
Styling the Marker
The
current
of list-item
. So the default arrow (▶) that comes with it is perhaps altered just like the default markers on HTML tips objects. We’re ready to vary the character that’s used, and independently change its coloration.
Altering the marker coloration
Let’s set the default marker to a selected coloration. Only for nice, let’s furthermore bump up the font dimension of the marker. We’re ready to do that with the ::marker
pseudo-element:
abstract::marker {
coloration: #e162bf;
font-size: 1.2em;
}
The result’s confirmed beneath.
It’s a pleasant, easy determination, though ::marker
sadly isn’t supported in Safari, so see completely totally different alternatives beneath if that’s a dealbreaker.
Altering the marker spacing
By default, the marker arrow is fairly near the abstract textual content material materials. Its list-style-position
is about to inside
. If we modify it to outside
, we’ll add dwelling between the abstract textual content material materials and the marker by along with some left padding. We furthermore want so as in order so as to add some left margin in order that the triangle doesn’t cling outside the container:
abstract {
list-style-position: outside;
margin-left: 30px;
padding: 10px 10px 10px 20px;
border-radius: 5px;
}
The result’s confirmed beneath.
I’ve exaggerated the spacing between the arrow marker and the abstract textual content material materials merely to make it apparent. Sadly, utilizing list-style-position: outside;
with the
Altering the marker type
The marker on our
abstract {
list-style-type: '⬇ ';
}
Uncover that we’ve used '⬇ '
(with an house subsequent to the arrow), which is an alternative choice to the spacing we tried above.
We now have a down arrow instead of a triangle. However … that down arrow gained’t change when the
difficulty has two states — closed
and open
— and we’ve solely set the marker vogue for the closed
state. So let’s furthermore set a marker for the open
state:
particulars[open] > abstract {
list-style-type: '⬆ ';
}
This time, we’ve used an up-pointing arrow. This offers us the consequence confirmed beneath.
Rattling! As rapidly as as quickly as additional, Safari lets us down, on account of it doesn’t help list-style-type
on the
We’re ready to strive all forms of completely totally different characters, akin to + and –, ✓ and Χ or ✗, ⋁ and ⋀ , and even have nice with completely totally different characters like ★ or vibrant fruits like 🍏 🍌 🍓 🍋 and 🍐, nonetheless evidently these characters will not work on all methods, so be significantly cautious, and as rapidly as as quickly as additional, list-style-type
positively gained’t work in Safari.
Making a Customized-made Marker for the abstract Ingredient
As we seen above, regardless that we can set a selected character for the default marker, and affords it types corresponding to paint and font dimension, there may be more likely to be elements with doing so. The next different might probably be to take away the marker altogether and create a very personalised diverse.
Eradicating the personalised marker
As with tips merchandise markers, we’ll take away the marker altogether:
abstract {
list-style: none;
}
abstract::-webkit-details-marker {
current: none;
}
The identical previous list-style: none
works on all browsers along with … (are you able to guess?) … Safari. A minimal of there’s a proprietary -webkit-
different on this case.
Uncover: one totally different decision to take away the marker from the
difficulty a current
worth of 1 issue aside from list-item
— akin to block
or flex
. This works in each browser along with … (do I even ought to say it?) … Safari.
Now our difficulty has no marker.
Having no marker offers no seen speedy in the least that this difficulty is clickable, so it’s not a very excellent thought to go away it at that.
Utilizing a background picture as a marker
We’d place a picture on the background, like so:
abstract {
list-style: none;
padding: 10px 10px 10px 40px;
background: url(arrow.svg) no-repeat 14px 50%;
background-size: 18px;
font-weight: daring;
}
The result’s confirmed beneath.
The draw once more of utilizing a background picture instantly on the
difficulty is open, on account of animations can’t be set instantly on background pictures in CSS. (We’d, in any case, use a selected picture for the open state, nonetheless we nonetheless couldn’t animate it, which is way extra nice.) So if we’re going to make the most of a background picture, it’s higher to put it on a ingredient that can be rotated and/or animated.
Utilizing a background picture as a marker with ::after
Let’s put the background picture inside an ::after
pseudo-element:
abstract {
current: flex;
}
abstract::after {
content material materials supplies: '';
width: 18px;
excessive: 10px;
background: url('arrow.svg');
background-size: cowl;
margin-left: .75em;
transition: 0.2s;
}
particulars[open] > abstract::after {
rework: rotate(180deg);
}
Correct proper right here’s a preserve demo of this code.
We’ve used current: flex
on the
The good difficulty about this setup is that we’re going to add animation to the arrow. (The animation doesn’t appear to work in Safari, nonetheless the habits is nice satisfactory, and I’m getting a bit fed up with this browser!)
Making the abstract difficulty look like a tab
We’ve been setting the
abstract {
current: inline-flex;
}
An event is confirmed beneath.
Limiting the width of the main points difficulty
In all of our examples so far, the
width: 50%;
. Or we’d would possibly set it to an inline current in order that it’s merely as huge as its content material materials supplies:
particulars {
current: inline-block;
}
Click on on on on the tab beneath to disclose the narrower width of the
Strive altering current: inline-block
to width: 50%
all through the Pen above.
Putting the marker arrow on the far finish of the abstract
Let’s do one issue a bit absolutely completely totally different now, inserting the marker arrow on the right-hand side of the
current: flex
, transferring the arrow to the far right is as simple as along with justify-content: space-between
to the
difficulty:
abstract {
current: flex;
justify-content: space-between;
}
Utilizing ::after as a marker with no background picture
There are completely totally different methods we’d use ::after
with out an actual picture. Correct proper right here’s an event that makes use of merely ::after
with borders:
abstract::after {
content material materials supplies: '';
width: 0;
excessive: 0;
border-top: 10px sturdy #15171b;
border-inline: 7px sturdy clear;
transition: 0.2s;
}
Correct proper right here’s a preserve demo.
Now we have now an arrow that rotates between the closed and open state. We’ve furthermore added a pleasant drop shadow to the
One totally different methodology to make the most of ::after
with out a picture is to put Unicode characters all by the content material materials supplies
property:
abstract::after {
content material materials supplies: "25BC";
transition: 0.2s;
}
This gadgets a triangle type (▼) as our marker, as confirmed in this CodePen demo.
There are literally tons of of Unicode symbols, and so they additionally’re fairly nice to seek out. Every comes with a code like U + 25BC
or U + 025BC
. To make the most of that code contained inside the content material materials supplies
property, take the characters after the +
and place them contained inside the content material materials supplies
quotes, with a on the doorway:
content material materials supplies: "25BC"
. If there’s quite a lot of zeros at first, you most likely can go away them out. (As an illustration, U + 02248
can rework " 2248"
or "2248"
.)
Thus far, the issues we’ve carried out above are increased than satisfactory, nonetheless there are completely totally different factors we could have nice with, so let’s merely play with just a few of them correct proper right here.
Hover have an effect on on the main points difficulty
We’re ready to set diversified hover outcomes on the
particulars {
transition: 0.2s background linear;
}
particulars:hover {
background: #dad3b1;
}
Whereas we’re at it, let’s furthermore transition the
open
state:
particulars > abstract {
transition: coloration 1s;
}
particulars[open] > abstract {
coloration: #d9103e;
}
The result’s confirmed beneath.
We might also merely set a background change on the
Animating the opening and shutting of the main points difficulty
Haha, fooled ya! It seems it’s not potential to animate the opening and shutting of the
Sadly, presently, there’s no built-in decision to animate the transition between open and closed.
Nonetheless, this performance is coming quickly (as of late 2024) by means of calc-size(auto)
. (Correct proper right here’s an event of one of the simplest ways it’d work.)
Contained in the meantime, we could have a little bit of little little bit of nice by animating the contents of the
particulars article {
opacity: 0;
}
particulars[open] article {
animation: fadeIn .75s linear forwards;
}
@keyframes fadeIn {
0% {
opacity: 0;
}
100% {
opacity: 1;
}
}
The result’s confirmed beneath.
One totally different trick might probably be to slip all through the content material materials supplies, like so:
particulars {
overflow: hidden;
}
particulars[open] article {
animation: animateUp .5s linear forwards;
}
@keyframes animateUp {
0% {
opacity: 0;
rework: translatey(100%);
}
100% {
opacity: 1;
rework: translatey(0);
}
}
The result’s confirmed beneath.
It’s a bit tacky, and probably overkill, nonetheless price making an attempt anyway. Sadly, these animations solely work the primary time the problem is clicked (until the browser devtools are open, for some bizarre set off!). You primarily want the intervention of JavaScript to make the have an effect on work repeatedly.
Altering abstract content material materials supplies in open and closed states
Contained in the demos above, the has at all times had the same textual content material materials, whether or not or not or not the
::after
pseudo-element:
abstract::after {
content material materials supplies: " to stage out hidden content material materials supplies";
}
particulars[open] abstract::after {
content material materials supplies: " to cowl extra content material materials supplies";
}
That offers us the consequence confirmed beneath.
Altering the abstract cursor
The default cursor (or mouse pointer) for the
textual content material materials.
For nice, let’s change to the hand cursor (or “pointer”):
abstract {
cursor: pointer;
}
This gadgets the mouse pointer to a hand when hovering anyplace over the
We’d set the cursor on the
difficulty. I choose to maintain up it merely on the problem we’re meant to click on on on, although.
Altering the accessibility focus types
If we’re navigating a web based internet web page by means of the keyboard, we’ll tab to the
difficulty has a default define. The picture beneath shows what this appears to be like like in diversified browsers.
They’re quite a few a muchness: principally a easy, darkish (blue or black), sturdy define that’s about 3px
huge.
There are fairly just a few types we’d set for the centered
abstract:focus {define: none;}
abstract:focus-visible {define: 3px dotted #ff0060;}
abstract {padding: 10px;}
By default, the precept objective define doesn’t current after we click on on on on the
difficulty with a mouse). So all through the code above, we’ve set the define
to none
and instead used focus-visible
to set the classes, as this means the precept objective types will solely be seen to keyboard shoppers (for whom it’s truly helpful).
The picture beneath shows our new styling.
Correct proper right here’s a preserve demo.
We’d have a whole lot of nice with this, utilizing animations, background colours and so forth when the
Utilizing quite a lot of particulars components like an accordion tips
As of 2024, we’ll create an “distinctive accordion” have an effect on in some browsers. That’s, we’ll create an accordion with quite a lot of particulars
components the place one closes when one totally different opens — through the use of the decide
attribute. We merely put the same decide
attribute on any difficulty we want as a part of the accordion — akin to decide="distinctive"
. (These associated particulars
components is more likely to be anyplace on the web internet web page; they don’t must be side by side!)
Correct proper right here’s an event:
particulars decide="distinctive" open>
abstract>Distinctive accordionsabstract>
article>
p>I shall be open when the online internet web page a lot (on account of code>opencode> attribute, nonetheless I’ll shut when the next code>particularscode> difficulty is clicked.p>
article>
particulars>
particulars decide="distinctive">
abstract>Click on on on me instead!abstract>
article>
p>As quickly as we open this code>particularscode> difficulty, the one above it'll shut.p>
article>
particulars>
If older browser help is essential, there are some nifty examples of doing it with JavaScript (akin to correct proper right here, correct proper right here, correct proper right here and correct proper right here).
We might also use CSS to vogue the presently open difficulty in some other case from the others, utilizing quite a lot of the strategies we’ve lined above.
Correct proper right here’s a easy event:
particulars {
background-color: #2196F3;
}
particulars[open] {
background-color: #ce0e99;
}
Styling a heading contained inside the abstract
Some builders, involved concerning the constructing of their HTML, want to put a heading difficulty contained inside the
current: inline
or current: inline-block
:
abstract h2 {
current: inline;
}
You might even see try a demo of this on CodePen.

As we’ve tried to stage out above, there are quite a few easy methods to vogue the
think about Safari.)
There have been makes an attempt to animate the opening and shutting of the
