Make Your Website Responsive – Your Options

You can make your website responsive in several ways:

By coding it yourself with HTML, CSS, Flexbox, Grid, and media queries.
By using a responsive template or website builder that handles most of the work for you.
Or with a platform like UltimateWB that has a built-in Responsive App, letting you customize layouts both without coding and with coding. It’s flexible, scalable, beginner-friendly, yet powerful enough for experts.

This guide will help you understand what responsive design is, explore the no-code options, and show how coding can give you extra control.

What “Responsive” Means

A responsive website automatically adapts its layout and content to fit any screen size. It eliminates horizontal scrolling, broken elements, and awkward resizing, giving users a seamless experience on phones, tablets, and desktops.

With a clear understanding of responsive design, you can choose the approach that fits your skills and goals.

No-Code Approach: Easy and Flexible

If you want to create a responsive website without touching code, modern platforms make it simple:

UltimateWB: The built-in Responsive App automatically adapts your site across devices while allowing full customization of layouts, spacing, and styling. You can tweak designs visually or add custom code if needed.
Other builders/templates: Platforms like Wix, Squarespace, and Webflow offer responsive tools and pre-made templates, though customization may be more limited.

No-code tools save time, reduce errors, and are perfect for beginners, yet platforms like UltimateWB are flexible enough for advanced users.

Optional: Coding Your Responsive Website

For those who want complete control, you can make a website responsive manually. Here’s a practical guide:

1. Start with the Viewport Meta Tag

<meta name="viewport" content="width=device-width, initial-scale=1">

This ensures the browser uses the device’s width instead of scaling a desktop layout down.

2. Use Flexible Layouts

Avoid fixed widths. Use percentages, em, rem, or CSS layout systems like Flexbox or Grid:

.container {
  width: 90%;
  margin: 0 auto;
}

.column {
  flex: 1 1 30%;
}

Columns now grow, shrink, and reflow naturally on different devices.

3. Responsive Images and Media

img {
  max-width: 100%;
  height: auto;
}

Use srcset to serve appropriately sized images for each device, improving load times and performance.

4. Add CSS Media Queries

@media (max-width: 768px) {
  .navigation {
    display: none;
  }
}

You can either think mobile-first – start with phone styles, then add tablet and desktop adjustments – or the other way around.

5. Organize Content Logically

Use blocks or cards that stack or wrap naturally.
Flexbox or Grid lets you reorder or resize elements without changing HTML.

This keeps content readable and usable across devices.

6. Optimize Typography and Spacing

Use em or rem for font sizes.
Adjust line spacing and margins via media queries.
Avoid tiny mobile text or oversized desktop text.

Good typography boosts engagement and reduces bounce rates.
