Introduction to Adaptive Makeup

Adaptive layout is an approach in which a website or application is designed so that it automatically adapts to different screens and devices. Instead of creating separate versions for each device, adaptive layout allows you to create one universal version that displays optimally on all devices.

Example of adaptive css layout on different devices

The main goal of adaptive layout is to give users the best possible visual and functional experience whether they are using a desktop, tablet, smartphone or other device. By using CSS and other techniques, adaptive layout can provide optimal layout and size of elements, easy navigation and responsiveness on different screens.

Basics of CSS Media Queries

One of the key tools in adaptive layout is CSS Media Queries. Media Queries allow you to apply different CSS styles based on the characteristics of the device and the screen on which the website is displayed. For example, you can specify different styles for devices with a screen width less than 768 pixels and devices with a screen width greater than 768 pixels.

An example of using CSS Media Queries:

@media screen and (max-width: 768px) {
  /* Styles applied on devices with screen widths up to 768px */
}

@media screen and (min-width: 769px) {
  /* Styles applied on devices with a screen width of 769 pixels or more */
}

Media Queries support different characteristics such as screen width and height, device orientation, pixel density, etc. This allows you to develop adaptive styles for a wide range of devices and screens.

Flexible grid using Flexbox

Flexible grid is a key component of adaptive layout. It allows you to create adaptive layouts that can change depending on screen size. Flexbox is a powerful CSS tool to create flexible and responsive grids.

With Flexbox you can easily arrange elements in rows and columns, control their size, order and alignment. This allows you to create adaptive layouts that automatically change and rearrange as the screen size changes.

Example of a flexible grid using Flexbox:

.container {
  display: flex;
  flex-wrap: wrap;
}
.item {
  flex: 1 0 300px;
}

In this example, .container is the container in which the .item elements are placed. The display: flex property turns the container into a flexible grid. With flex-wrap: wrap, the elements are automatically moved to a new line when there is not enough space.

Adaptive images and media queries

Adaptive images play an important role in creating adaptive websites. Images can take up a lot of space and affect performance, so it’s important to optimize their display on different devices.

CSS Media Queries allow you to control the size and resolution of images depending on the screen. You can use different media queries to specify different images for different screen sizes or devices.

An example of adaptive images using media queries:

.image {
  width: 100%;
  height: auto;
}
@media screen and (min-width: 768px) {
  .image {
    width: 50%;
  }
}

In this example, the .image will take up 100% of the width of the container on all devices. However, if the screen is wider than 768 pixels, it will only take up 50% of the container width. This allows you to control the size of images and ensure optimal display on different screens.

Mobile Menu with CSS

Mobile menu is an important part of adaptive layout. Instead of the traditional horizontal menu on the desktop, mobile devices often use a drop-down menu or a menu icon to save screen space.

Hidden mobile menu on desktop with css

CSS allows you to create a mobile menu using animations and element transformations. Using media queries, you can specify different styles for mobile and desktop menus.

Button-driven mobile css menu

An example of a mobile menu using CSS:

<pre class="wp-block-syntaxhighlighter-code"><nav class="menu">
  <input type="checkbox" id="toggle">
  <label for="toggle" class="toggle-btn">Menu</label>
  <ul>
    <li><a href="#">Home</a></li>
    <li><a href="#">About us</a></li>
    <li><a href="#">Services</a></li>
    <li><a href="#">Contacts</a></li>
  </ul>
</nav></pre>
.menu {
  display: flex;
  flex-direction: column;
}
.toggle-btn {
  display: none;
}
@media screen and (max-width: 768px) {
  .toggle-btn {
    display: block;
    cursor: pointer;
  }
  ul {
    display: none;
  }
  #toggle:checked ~ ul {
    display: block;
  }
}

In this example, the mobile menu is hidden by default. When you click the .toggle-btn label, the menu opens or closes with animations and element transformations. Media queries allow you to apply styles only on mobile devices with a screen width of up to 768 pixels.

Mobile-First approach

Mobile-First is an approach to adaptive layout in which a website or application is first developed for mobile devices and then gradually improved for larger screens. This approach is based on the assumption that most users first visit the site from a mobile device.

Mobile-First involves using minimal CSS styles for mobile devices and adding additional styles for larger screens using media queries. This optimizes site loading and performance on mobile devices.

An example of the Mobile-First approach:

body {
  font-size: 14px;
}
@media screen and (min-width: 768px) {
  body {
    font-size: 16px;
  }
}

In this example, the font size is set to 14 pixels for mobile devices. For screen widths of 768 pixels and above, the font size is increased to 16 pixels. This allows you to create a more comfortable reading experience on larger screens while maintaining an optimal font size on mobile devices.

Practical examples of adaptive layout

  • Adaptive header

The header is one of the key elements of adaptive layout. It usually contains a logo, navigation and other important elements. Adaptive header should change its appearance and location to better fit different devices and screens.

Adaptive header on the desktop

Example of an adaptive website header:

<pre class="wp-block-syntaxhighlighter-code"><header class="header">
  <div class="logo">
    <img src="logo.png" alt="Logo">
  </div>
  <nav class="navigation">
    <ul>
      <li><a href="#">Home</a></li>
      <li><a href="#">About us</a></li>
      <li><a href="#">Services</a></li>
      <li><a href="#">Contacts</a></li>
    </ul>
  </nav>
</header></pre>
.header {
  display: flex;
  align-items: center;
}
.logo {
  flex: 1;
}
.navigation {
  flex: 2;
}
@media screen and (max-width: 768px) {
  .header {
    flex-direction: column;
  }
  .navigation {
    order: -1;
    margin-top: 10px;
  }
}

In this example, the website header contains a .logo and a .navigation. With Flexbox, the header adapts to different devices. When the screen width is less than 768 pixels, the header is rebuilt vertically, and the navigation is moved above the logo for better readability on small screens.

  • Adaptive Image Gallery Layout

An image gallery is often used on websites to display a collection of photos or images. An adaptive gallery layout should change its layout and number of columns depending on the screen size to make the best use of the available space.

Adaptive image gallery on the desktop

An example of an adaptive image gallery layout:

<pre class="wp-block-syntaxhighlighter-code"><div class="gallery">
  <img src="image1.jpg" alt="Image 1">
  <img src="image2.jpg" alt="Image 2">
  <img src="image3.jpg" alt="Image 3">
  <!-- Another image -->
</div></pre>
.gallery {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(300px, 1fr));
  gap: 10px;
}
.gallery img {
  width: 100%;
  height: auto;
}
Adaptive image gallery on tablet

In this example, the image gallery is created using CSS Grid. The grid-template-columns property specifies a flexible grid that automatically rebuilds and adapts as the screen size changes. Each image occupies a minimum of 300 pixels and is automatically distributed in the available space.

  • Adaptive Contact Form

The contact form is one of the most important elements of interaction with the user on the website. The adaptive contact form should be easy to fill out on different devices and screens while maintaining its look and functionality.

Adaptive contact form on desktop

An example of an adaptive contact form:

<pre class="wp-block-syntaxhighlighter-code"><form class="contact-form">
  <div class="form-group">
    <label for="name">Name:</label>
    <input type="text" id="name" name="name">
  </div>
  <div class="form-group">
    <label for="email">Email:</label>
    <input type="email" id="email" name="email">
  </div>
  <div class="form-group">
    <label for="message">Message:</label>
    <textarea id="message" name="message"></textarea>
  </div>
  <button type="submit">Send</button>
</form></pre>
.contact-form {
  display: grid;
  grid-template-columns: 1fr;
  gap: 10px;
}
.form-group {
  display: grid;
  gap: 5px;
}
@media screen and (min-width: 768px) {
  .contact-form {
    grid-template-columns: 1fr 1fr;
  }
}
Adaptive contact form on tablet

In this example, the contact form is created using CSS Grid. When the screen width is less than 768 pixels, the form is displayed in one column for better readability on small screens. When the screen width is 768 pixels or larger, the form is rebuilt in two columns to make better use of the screen width.
