Create a Responsive Slider with jQuery (Source Code)

A hero section is the first thing visitors see when they visit a website, and it's important to make it stand out. It usually includes a bold headline, catchy text, and a call-to-action (CTA) button. In this blog, you'll learn how to create a marketing hero section using HTML and CSS. This guide is perfect for beginners, and by the end, you'll have a simple, professional hero section for your website.

Prerequisites:

Before you start, you should have a basic understanding of:

HTML (HyperText Markup Language)
CSS (Cascading Style Sheets)
A text editor like Visual Studio Code or Sublime Text
Web browser to preview your work

Source Code

Step 1 (HTML Code):

Start by creating the basic HTML structure. This will include a container, headline, text, and button inside your hero section.

Here's a breakdown of the key components:

`<!DOCTYPE html>`

Defines the document as an HTML5 document.

`<html lang="en">`

Starts the HTML document and specifies the language as English.

`<head>`

Contains meta information and links to resources like fonts, stylesheets, and the page's title.

<meta charset="UTF-8">: Defines the character encoding as UTF-8.
<meta name="viewport" content="width=device-width, initial-scale=1.0">: Ensures proper scaling on mobile devices.
<title>: Sets the page's title to "Marketing Hero Section."
Google Fonts: Loads the Roboto font from Google Fonts.
Stylesheet link: Links to an external CSS file (styles.css), where the styling for the webpage is defined.

`<body>`

The body contains all the visible content, including the navigation bar and the hero section.

`<nav>` (Navigation bar)

Contains the site logo, a menu, and actions (like login and "Get started" buttons).
Logo: An image linked to the homepage (logo.svg).
Menu: A list of links such as "How it works," "Goals," etc.
Mobile menu: Includes buttons for opening/closing the menu with an icon button using svg graphics.
Actions: Provides "Login" and "Get started" buttons.

`<main>` (Main content)

Hero Section: The main visual part of the page.
- Hero visual: Displays three autoplaying videos (video-1.mp4, video-2.mp4, video-3.mp4) that loop and are muted.
- Hero content: Displays the main headline and action buttons.
  - Headline: Rotating messages like "Elevate your brand", "Increase Sales", and "Inspire audiences".
  - Call to Action (CTA): A button prompting users to "Get started."
  - Scroll Button: A button to scroll down, with a downward arrow represented using an svg icon.

Scripts and Interaction

JavaScript is used to open/close the mobile navigation menu by adding/removing the open class with nav.classList.add('open') and nav.classList.remove('open')

HTML and CSS Tips: Creating Engaging UI Comments Section

Step 2 (CSS Code):

Next, add CSS to style your hero section. Let's break it down into sections:

1. @import

@import 'https://unpkg.com/[email protected]' layer(library);

This imports a library called "Open Props," which provides a set of reusable design tokens (CSS variables) for colors, spacing, typography, etc.

2. @layer reset

@layer reset {
  *,:before,:after {
    box-sizing: border-box;
  }
  :where(:not(dialog)) {
    margin: 0;
  }
}

This reset layer is setting a consistent box-sizing: border-box for all elements, including ::before and ::after. This helps ensure padding and borders are included within the element’s width and height.
It also removes default margins from all elements except <dialog> using the :where() selector.

3. @layer base

@layer base {
  :root {
    color-scheme: dark;
    font-family: 'Inter', sans-serif;
    --palette-hue: 249;
    --red: #e81155;
    --surface-1: black;
    --surface-invert: white;
    --text-1: white;
    --highlight-text: var(--red);
    --headline1-font-size: var(--font-size-fluid-3);
    ...
  }
  body {
    background-color: var(--surface-1);
    color: var(--text-1);
    font-size: var(--body-font-size);
    min-block-size: 100dvb;
  }
}

The :root defines global variables (CSS custom properties) for colors, font sizes, and spacing. These variables can be reused throughout the document.
color-scheme: dark sets the default theme to dark mode.
Variables like --palette-hue, --surface-1, and --highlight-text control the hue, background color, and highlight color, respectively.
The body styles set a black background and white text for the entire page.

4. Navigation and Menu Styling (@layer App)

@layer App {
  .nav {
    display: grid;
    place-items: center;
  }
  .nav-container {
    display: grid;
    grid-auto-flow: column;
    gap: var(--space-md);
  }
  ...
  @media (width < 1056px) {
    padding-inline-start: var(--space-md);
    padding-inline-end: var(--space-sm);
  }
}

Navigation-related classes (.nav, .nav-container, .menu-wrapper) use grid layout to structure the navigation bar.
For smaller screen sizes (@media width < 1056px), padding and layout adjustments are applied to make the layout responsive.

5. Buttons

.button-link {
  font-size: var(--button-link-font-size);
  background-color: var(--button-link-face);
  color: var(--button-link-text);
  &:hover {
    background-color: var(--button-link-hover-face);
  }
  &.primary {
    background-color: var(--button-link-primary-face);
  }
}

.button-link is a generic button style with custom properties for font size, color, and hover effects.
The .primary class modifies the button with a primary background color and custom hover behavior.

6. Animations

@keyframes animate-ratio {
  from {
    aspect-ratio: 16/9;
    clip-path: inset(0 0);
  }
  to {
    aspect-ratio: 2.5/6;
    clip-path: inset(120px 0 50px 0);
  }
}
@keyframes push-up {
  10%, 90% {
    transform: translateY(-100%);
  }
  100% {
    transform: translateY(-200%);
  }
}

@keyframes animate-ratio animates the aspect ratio and clip path of elements (useful for visual transitions).
push-up animates vertical scrolling of elements with a translateY transformation.

7. Responsive Design

@media (width >= 700px) {
  --headline1-font-size: var(--extend-font-size-fluid-4);
}
@media (width < 1056px) {
  --nav-link-font-size: var(--font-size-3);
}

Media queries adjust font sizes, padding, and layout for different screen widths. For example, the headline font size becomes larger on screens wider than 700px, and the navigation link font size becomes larger on screens smaller than 1056px.

@import 'https://unpkg.com/[email protected]' layer(library);

@layer reset {
  *,
  ::before,
  ::after {
    box-sizing: border-box;
  }

  :where(:not(dialog)) {
    margin: 0;
  }
}

@layer base {
  :root {
    color-scheme: dark;
    font-family: 'Inter', sans-serif;
    --palette-hue: 249;
    --palette-hue-rotate-by: 0;
    --palette-chroma: 0;
    --red: #e81155;
    --extend-font-size-fluid-4: clamp(3.5rem, 4.333vw, 4.5rem);

    --surface-1: black;
    --surface-invert: white;
    --text-1: white;
    --text-invert: black;
    --brand: var(--red);

    --space-xxs: var(--size-1);
    --space-xs: var(--size-2);
    --space-sm: calc(var(--size-1) + var(--size-2));
    --space-md: var(--size-3);
    --space-lg: var(--size-7);

    --radius-sm: var(--radius-2);

    --button-link-block-size: 3.25em;
    --button-link-min-inline-size: 7em;
    --button-link-border: var(--border-size-1) solid currentColor;
    --button-link-face: transparent;
    --button-link-text: white;
    --button-link-hover-face: color-mix(in oklch, white, transparent 80%);
    --button-link-primary-text: white;
    --button-link-primary-face: var(--red);
    --button-link-primary-border: none;
    --button-link-primary-hover-face: color-mix(
      in oklch,
      var(--red),
      transparent 20%
    );
    --button-link-border-radius: var(--radius-round);
    --nav-logo-inline-size: var(--size-12);
