Scrollers create an accessible container while providing visual cues that help users and navigate.

Adding content#

The scroller component automatically provides a scrollable container for any content that exceeds the available space. Simply add your content as children of the <pc-scroller> element and it will handle the rest.

<pc-scroller>
    <div style="inline-size: 1200px; padding: var(--pc-spacing-l)">
        <h3>Superhero Team Roles Guide</h3>
        <div

                <p>
                    Charismatic captains like Captain America or Cyclops are the
                    heart of any superteam, rallying everyone with epic speeches
                    and killer strategies. They’re the ones calling the shots in
                    a cosmic showdown, keeping the squad focused when Thanos or
                    Magneto crashes the party.

                    Powerhouses like Thor or Hulk bring the boom, smashing
                    through villain lairs or alien armadas. Their job is to land
                    the big punches, but they gotta pace themselves to avoid
                    stealing the spotlight from sneakier teammates.

                <h4>Tech geniuses</h4>
                <p>
                    Brainiacs like Iron Man or Mr. Fantastic keep the team one
                    step ahead with gadgets and gizmos. They’re crafting
                    quinjets or hacking evil AI, always ready with a snarky quip
                    while saving the day from a computer terminal.

                <p>
                    Ninja‐like heroes like Black Widow or Nightcrawler slip
                    through the shadows, gathering intel or pulling off surprise
                    attacks. They’re the glue that makes risky plans work,
                    coordinating with the team to flip a losing fight into a
                    win.

Orientation#

Set the orientation attribute to vertical and provide a height to create a vertical scroller.

        Superhero movies are the ultimate popcorn‐fueled thrill rides, turning
        comic book pages into cinematic rollercoasters. Back in the early 2000s,
        films like X‐Men and Spider‐Man kicked open the door, proving tights and
        teamwork could pack theaters. Those early flicks leaned on practical
        effects and heart‐like Tobey Maguire’s earnest web‐slinger saving a
        train—making us believe a guy in spandex could be a hero. They weren’t
        perfect, but they set the stage for the genre to become a cultural
        juggernaut.
    </p>
    <p>
        By the 2010s, the Marvel Cinematic Universe turned superhero films into
        a shared saga, like a comic crossover event on steroids. The Avengers in
        2012 was a game‐changer, tossing Iron Man’s snark, Thor’s hammer, and
        Cap’s shield into one epic brawl. Directors learned to balance humor,
        heart and explosions, while studios figured out how to make every movie
        feel like a chapter in a bigger story. Even standalone hits like Wonder
        Woman brought fresh vibes, with Gal Gadot’s lasso‐wielding warrior
        stealing hearts and smashing box office records.
    </p>
    <p>
        Today, superhero flicks are a global obsession, from Deadpool’s
        chimichanga‐fueled chaos to Black Panther’s Wakandan pride. They’re not
        just about powers—they’re about characters we root for, like Rocket
        Raccoon’s scrappy loyalty or Harley Quinn’s wild energy. Fans dissect
        trailers like detectives, theorizing about multiverses and cameos, while
        memes of sad Affleck or dancing Groot flood the internet. Whether it’s a
        gritty Joker origin or a cosmic Guardians adventure, these movies keep
        us glued to our seats, dreaming of heroism and one‐liners that’d make
        even Tony Stark jealous.

No shadow#

Use the no-shadow attribute to remove the fading shadow effect at the edges of the scroller.

            Gaming consoles are like time machines for nerds, zapping us from
            pixelated 2D adventures to jaw‐dropping cinematic worlds. Back in
            the ’90s, the Super Nintendo was the cool kid on the block, using a
            16‐bit chip to pull off tricks like Mode 7, which made Mario Kart’s
            tracks feel like they were zooming right at you. It was like
            wizardry for a kid with a chunky controller, turning flat sprites
            into pseudo‐3D races that had us yelling at our TVs when we got hit
            by a red shell.
        </p>
        <p>
            Fast‐forward to today, and consoles like the PlayStation 5 and Xbox
            Series X are basically supercomputers in sleek boxes. They’re
            packing enough power to make games look like Hollywood blockbusters,
            with lighting so real you can practically feel the sun glare in
            Spider-Man: Miles Morales. These machines can handle massive open
            worlds, like the sprawling lands of Elden Ring, without breaking a
            sweat, letting you swing swords or race cars while your living room
            feels like a sci‐fi movie set. It’s a far cry from the SNES days,
            but the vibe’s the same: pure, controller‐gripping fun.
        </p>
        <p>
            What makes consoles the heart of gaming culture is how they bring
            everyone together, from casual players to hardcore speedrunners.
            Whether it’s your uncle fumbling through Super Mario World in 1992
            or your best friend screaming during a late‐night Call of Duty
            match, consoles are the ultimate couch co‐op machines. Modern
            systems even let you stream your clutch Fortnite wins to the world
            or jump into crossplay with PC pals. From the GameCube’s quirky
            handle to the Switch’s grab‐and‐go joy‐cons, every console’s got its
            own personality, making every era of gaming feel like a legendary
            chapter in a never‐ending quest.

No scrollbar#

Use the no-scrollbar attribute to hide the scrollbar while maintaining scroll functionality. This creates a cleaner visual appearance but may reduce usability on content that needs a clear scrolling indicator.

        <p>
            Dungeons & Dragons 5e is the blockbuster superhero flick of tabletop
            RPGs, turning every session into an epic tavern brawl or
            dragon‐slaying saga. Unlike the old 3.5e days, where you’d stack +30
            bonuses like a mathlete on a mission, 5e keeps things chill with
            skill checks capping around +11—like a +5 from your slick Charisma
            and +6 from being a pro at persuasion. This means even a squad of
            scrappy kobolds can give your level 10 barbarian a bad day if you
            roll poorly. It’s like the game’s saying, “Sure, you’re a hero, but
            don’t get cocky!”
        </p>
        <p>
            The advantage and disadvantage system is 5e’s secret sauce, making
            every dice roll feel like a movie cliffhanger. Instead of juggling a
            dozen modifiers, you just roll two d20s and take the better (or
            worse) one, which shakes out to about a +5 or −5 vibe shift. It’s
            like your rogue’s got a lucky charm when sneaking past guards or a
            cursed boot when dodging a fireball. This keeps the game’s flow
            snappy, so you’re not stuck crunching numbers when you could be
            roleplaying a dramatic speech to charm a dragon or bluffing your way
            out of a bandit ambush.
        </p>
        <p>
            5e’s world is built for storytelling, not just stat sheets, and
            that’s why it’s the king of game nights. The rules are flexible
            enough for your DM to whip up a haunted forest crawl or a pirate
            ship heist without needing a PhD in game design. Classes like the
            warlock let you make shady pacts with cosmic entities, while feats
            like Tavern Brawler turn your monk into a bar‐fighting legend who
            can knock out goblins with a chair. Whether you’re a newbie rolling
            your first d20 or a veteran plotting a castle siege, 5e’s vibe is
            all about epic moments—like when your party’s wizard crits on a
            fireball and you all cheer like you just won the Super Bowl.
