How to Design a Fluid Hero Section in Divi

A website’s hero section is one of the best candidates for fluid design. Unlike traditional responsive design that adjusts at different breakpoints, fluid design scales seamlessly with the browser viewport and keeps the design consistent on any device. After all, the hero section is the first thing users see on a website.

You may have seen fluid design demonstrated in previous tutorials on fluid typography, fluid modules, and/or fluid buttons. In this tutorial, we are going to show you how to create an entire fluid hero section in Divi. The key to creating this fluid design is adding a fluid root font size to each of the modules used and then incorporating the em length unit (which is relative to the root body font size) throughout the module’s settings.

Let’s get started!

Sneak Peek

Here is a quick look at the design we’ll build in this tutorial.

3. Choose the option “Build From Scratch”.

After that, you will have a blank canvas to start designing in Divi.

How to Design a Fluid Hero Section in Divi

To build the fluid hero section, we are going to add a fluid root font size to each of the three modules. These modules will make up the heading, subtitle, and button. Then we are going to use the em length unit within the modules design settings to make sure the design elements are relative to the fluid root font size. Then we are going to position the image on the left side of the page with an absolute position and offset. The result will be a fluid hero section that scales perfectly with the viewport width so that the design is consistent on all devices.

Section Settings

To start, let’s update the existing design settings for the section. Open the section settings and update the following:

• Background Gradient Left Color: #ff2000
• Background Gradient Right Color: #121212
• Gradient Direction: 45deg
• Start Position: 30%
• End Position: 0%

Under the design tab, update the padding:

• Padding: 0px top, 0px bottom

Create Row

Next, add a one-column row to the section.

Row Settings

Open the settings for the row and update the following under the design tab:

• Gutter Width: 1
• Width: 100%
• Max Width: 1700px
• Min Height: 100vh (desktop), none (tablet and phone)
• Padding: 0px top, 0px bottom

Create Fluid Heading Text with Border

Now that the section and row are finished, we can add the fluid heading text to the hero section. We are also going to add a fluid border to the text module for a creative design element.

Add Text Module

To create the heading text and border, add a new text module to the column.

Text Settings

Under the content tab, update the body content with the following HTML:

<h1>Fluid Fullscreen Page Design<span style="color: #ff2000;">.</span></h1>

To make the design elements fluid, we first need to add a fluid root font size to the module using the CSS Clamp() function. Under the advanced tab, past the following CSS snippet:

font-size: clamp(32px, 4.1vw, 70px);

With the fluid root font size in place, we are ready to update the design settings. It is important to use the em length unit throughout because the em length unit is relative to the element’s root font size.

Under the design tab, update the following heading text design settings:

• Heading Type: H1
• Heading Font: Montserrat
• Heading Font Weight: Heavy
• Heading Text Color: #ffffff
• Heading Text Size: 1em
• Heading Letter Spacing: 0.1em
• Heading Line Height: 1.2em

Also, update the modules padding as follows:

• Padding: 1em (top, bottom, left, right)

To create the fluid border design, update the following:

• Border Width: 1em
• Border Color: #ffffff
• Bottom Border Color: transparent
• Left Border Color: transparent

Creating the Accent Border

To create the accent border, we can duplicate the existing text module.

Take out the existing body content and update the design settings as follows:

• Max Width: 6.5em
• Height: 3.25em
• Border Width: 0.5em
• Border Color: #ff2000

Remember, the same fluid root font size is included in this duplicate module. So, we can use the em length unit to adjust the size and width of the border. This will make sure the design will adjust along with the design of the heading text module.

To position the accent border, add an absolute position with an offset that is equal to the width of the border in the heading text module (1em). Under the advanced tab, update the following Position options:

• Position: Absolute
• Location: top right
• Vertical Offset: 1em
• Horizontal Offset: 1em

Create the Fluid Subtitle Body Text

Below the heading text, we are going to add the fluid subtitle body text. Because this text is smaller, we are going to add a smaller fluid root font size.

Add New Text Module

To create the subtitle text, add a new text module below the existing heading text module.

You can add a few sentences of filler text as follows:

• Body Content: Vestibulum ac diam sit amet quam vehicula elementum sed sit amet dui. Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Add Fluid Root Font Size

Next, we need to add a new fluid font size that is more appropriate for smaller text. Under the advanced tab, paste the following CSS snippet under the Main Element:

font-size: clamp(14px, 1.4vw, 24px);

Text Design Settings

Under the design tab, update the following:

• Text Font Weight: Semi Bold
• Text Text Color: #ffffff
• Text Text Size: 1em
• Text Line Height: 1.6em

Then update the size and spacing as follows:

• Max Width: 19em
• Margin: 2em bottom, auto left, 5em right

Create the Fluid Button

To create the fluid button, add a new button module below the subtitle text module.

Then update the button text to read “7 Day Free Trial”.

Add Fluid Root Font Size

Next, we need to add a new fluid font size that is appropriate for a button. Under the advanced tab, paste the following CSS snippet under the Main Element:

font-size: clamp(20px, 2.35vw, 40px);

Button Design Settings

Under the design tab, update the following:

• Button Alignment: Right

• Button Text Color: #ff2000
• Button Background Gradient Left Color: transparent
• Button Background Gradient Right Color: #ffffff
• Gradient Direction: 45deg
• Start Position: 25%
• End Position: 0%
• Button Border Width: 0px
• Button Border Radius: 0px
• Button Font: Montserrat
• Button Font Weight: Heavy
• Button Font Style: Italic
• Button Icon: right triangle arrow (see screenshot)
• Button Icon Placement: Left

• Margin: 8em right
• Padding: 0.2em top, 0.2em bottom, 1.5em left, 1em right

Create Image for Hero Section

With all of the hero section content on the right size of the page, we are ready to add the hero section image to the left side. To do this, first add an image module under the button.

Open the image settings and upload an image.

Image Design Settings

Under the design tab, update the following settings:

• Image Alignment: Left (desktop and tablet), Center (phone)
• Max Width: 48% (desktop and tablet), 70% (phone)
• Padding: 4% Left

Finally, give the image an absolute position with an offset using vmin length unit as follows:

• Position: Absolute (desktop and tablet), Relative (phone)
• Location: Top Left (desktop and tablet)
• Vertical Offset 30vmin (desktop and tablet), 0px (phone)

Final Result

Here is the final result on a live page.

Here is how the fluid design scales smoothly with the browser viewport width.

Browser Support

The CSS clamp() function (used for the fluid font size in this tutorial) is surprisingly well supported by all major browsers except IE. There is a weird safari bug that doesn’t scale dynamically when adjusting the browser window, but does show correctly on page load. To fix this, all you seemingly need to do is give each of the modules a min-height of 0vw.

Final Thoughts

Adding fluid design to a hero section can be a convenient way to ensure the above-the-fold looks beautifully consistent on all browser sizes, without the hassle of updating the design at specific breakpoints or using media queries.
