Customizing Text and Heading Blocks

Text blocks are the foundation of content. Let’s explore their customization options.

Customizing Image Blocks

Images need customization beyond simple uploads. Here’s how to make images work perfectly in your design.

Resizing Images Visually

No code needed to adjust image sizes:

  1. Select your image block
  2. Method 1: Drag the corner handles
  3. Method 2: Use Dimensions panel in sidebar
    • Set width percentage (25%, 50%, 75%, 100%)
    • Or set exact pixel dimensions

Pro tip: Use 100% width for hero images, 50-75% for inline images, and 25-33% for icons or small graphics.

Image Alignment Options

Control how images sit within content:

  1. Select the image block
  2. Click alignment buttons in the toolbar:
    • Align left: Image floats left, text wraps right
    • Align center: Image centered, no text wrapping

    • Full width: Spans entire screen width

Adding Borders and Rounded Corners

Make images stylish without CSS:

  2. Open the Border panel in the sidebar
  3. Border width: Add a border (1-10px typical)
  4. Border color: Choose from palette
  5. Border radius: Round corners (0-50px or percentage)

Design examples:

  • Modern cards: 8-12px border radius with subtle border
  • Circular images: 50% border radius for perfect circles
  • Sharp professional: 0px radius with thin borders

Image Opacity and Duotone Effects

Create sophisticated visual effects:

Use case: Apply duotone effects to background images with overlaid text for consistent branding and better text readability.

Customizing Button Blocks

Buttons drive actions. Customize them to match your brand and increase clicks.

Button Colors and Styles

Transform plain buttons into branded CTAs:

  1. Select your button block
  2. Text color: Click Text in Color panel
  3. Background color: Click Background in Color panel
  4. Style variations: Choose from:
    • Fill: Solid background (default)
    • Outline: Border only, transparent background

Best practices:

  • Primary CTAs: Bold background colors (brand primary)

Button Size and Width

Control button dimensions visually:

  1. Select button block
  2. Font size: Adjust text size in Typography panel

  3. Border radius:
    • 0px: Sharp, professional corners
    • 5-10px: Subtle rounding (modern)
    • 25-50px: Pill-shaped buttons (playful)
  4. Border width: Add outline thickness if using outline style

Button Alignment

Position buttons effectively:

  • Left aligned: Standard for text-heavy content
  • Center aligned: Landing pages, CTAs
  • Right aligned: Contact sections, navigation
  • Justified: Full-width mobile buttons

Customizing Group and Container Blocks

Group blocks wrap other blocks, allowing complex layouts without code.

Adding Background Colors to Sections

Create visual sections on your pages:

  1. Insert a Group block
  2. Add content blocks inside the group
  3. Select the outer Group block
  4. In Color panel, set Background color

Design pattern: Alternating white and light gray backgrounds create visual rhythm on long pages.

Section Padding and Spacing

Control whitespace around sections:

  1. Select your Group block
  2. Open Dimensions panel
  3. Padding: Space inside the group (around content)
    • Top padding: Space above content
    • Bottom padding: Space below content
    • Left/Right padding: Space on sides
  4. Margin: Space outside the group (between sections)

Recommended values:

  • Desktop: 60-100px top/bottom padding
  • Mobile: 40-60px top/bottom padding
  • Sides: 20-40px left/right padding

Full-Width Sections

Create edge-to-edge colored sections:

  1. Select your Group block
  2. Click the alignment button in toolbar
  3. Choose Full width
  4. The background color now extends to screen edges
  5. Content remains centered (unless you change alignment)

Use case: Hero sections, testimonials, call-to-action sections, and footer areas work great at full width.

Customizing Column Blocks

Columns enable side-by-side layouts without coding.

Creating Column Layouts

  1. Type /columns or click + > Columns
  2. Select your column configuration:
    • Two columns (50/50)
    • Two columns (33/66)

    • Three columns (equal)
    • Custom: Manual configuration
  3. Add content to each column

Adjusting Column Widths

Change column proportions visually:

  1. Select the Columns parent block (not individual columns)
  2. Drag the column divider lines left or right
  3. Or use Width percentage in sidebar for precision

Common layouts:

  • 50/50: Features, comparisons, image + text
  • 33/66: Sidebar + main content
  • 66/33: Main content + sidebar
  • 25/25/25/25: Four equal columns for features or team members

Column Spacing and Padding

Control gaps between columns:

  1. Select the parent Columns block
  2. In Dimensions panel, adjust Gap
  3. Larger gaps (30-50px) for distinct sections
  4. Smaller gaps (10-20px) for related content

Responsive Column Behavior

Columns automatically stack on mobile devices. Customize this:

  1. Select Columns block
  2. Preview on mobile using the responsive preview tool
  3. Columns stack vertically automatically
  4. Adjust individual column padding for mobile optimization

Pro tip: Test your column layouts on mobile devices to ensure content remains readable when stacked.

Customizing Cover Blocks

Cover blocks create hero sections with images and text overlays.

Adding Background Images

  1. Insert a Cover block
  2. Click Upload or Media Library to add image
  3. Your image becomes the background
  4. Add text blocks inside the Cover

Overlay Color and Opacity

Make text readable over busy images:

  1. Select the Cover block
  2. Open Color panel
  3. Choose Overlay color (typically black or brand color)

    • 0%: No overlay, full image visibility
    • 50%: Balanced visibility
    • 80%: Heavy overlay, text emphasis

Best practice: Use 40-70% opacity overlays to maintain image visibility while ensuring text readability.

Text Color on Cover Blocks

Ensure text stands out:

  1. Select text blocks inside the Cover
  2. Change Text color (white works best on dark overlays)
  3. Increase font size for hero headlines (40-80px)
  4. Add bold formatting for emphasis

Cover Block Height

Control how tall your hero sections appear:

  1. Select Cover block
  2. Find Minimum height in sidebar
  3. Set in pixels:

Block Spacing and Margins

Perfect spacing makes designs look professional:

  1. Select any block
  2. Open Dimensions panel in sidebar
  3. Adjust Margin values:
    • Top margin: Space above the block
    • Bottom margin: Space below the block
  4. Use consistent spacing (e.g., 20px, 40px, 60px) for visual harmony

Design rule: More whitespace = more elegant and easier to read.

Adding Borders to Any Block

Borders create visual separation:

  1. Select your block
  2. Open Border panel
  3. Border width: Thickness (1-5px typical)
  4. Border style: Solid, dashed, or dotted
  5. Border color: Choose from palette

  2. Open the Animation panel in sidebar
  3. Choose effect: Fade, slide, zoom, bounce, rotate

  6. Preview: See animations before publishing

Animation tips:

  • CTAs: Bounce or pulse
  • Sections: Fade in for subtle reveals

Pro tip: Use Quick Presets for one-click professional animations without adjusting individual settings.

Using Style Variations

Many blocks include built-in style variations for instant design changes.

What Are Style Variations?

Style variations are pre-designed looks for blocks that change colors, borders, shadows, and spacing with one click.

Accessing Style Variations

  1. Select a block (buttons, quotes, images work great)
  2. Look for Styles panel in sidebar
  3. Click different style options to preview
  4. Select your favorite

Blocks With Style Variations

  • Quote blocks: Default, large, plain styles
  • Separator blocks: Default, wide, dots styles
  • Table blocks: Default, stripes styles

Pro tip: After selecting a style variation, you can still customize colors, sizes, and spacing to fine-tune the look.

Creating Custom Block Patterns

Save your customized blocks as reusable patterns.

Why Create Custom Patterns

  • Consistency: Use the same design across pages
  • Speed: Insert complex layouts with one click
  • Brand standards: Maintain design guidelines
  • Client-proofing: Provide pre-designed sections for clients

How to Create Patterns

  1. Build and customize a section (e.g., testimonial with image, name, quote)
  2. Select all blocks in the section (Shift + click)
  3. Click three dots (⋮) in toolbar
  4. Choose Create Pattern
  5. Name your pattern (e.g., “Customer Testimonial”)
  6. Sync: Toggle on to make changes sync across uses
  7. Click Create

Using Your Custom Patterns

  1. Click + to add a block
  2. Select Patterns tab
  3. Find your custom pattern
  4. Click to insert
  5. Edit content while maintaining design

Example library: Create patterns for:

  • Team member bios
  • Product features
  • Pricing tables
  • Contact sections
  • FAQ items

Customization Best Practices

Follow these guidelines for professional results without coding.

1. Maintain Design Consistency

Use consistent styling across your site:

  • Colors: Stick to 2-3 primary colors
  • Font sizes: Define heading hierarchy (H1: 48px, H2: 36px, H3: 24px)
  • Spacing: Use multiples of a base unit (20px, 40px, 60px, 80px)
  • Border radius: Consistent rounding across buttons, images, boxes

Tool: Create a style guide document with your standard values.

2. Think Mobile-First

Test all customizations on mobile:

  1. Use the Preview button
  2. Select Mobile device view
  3. Check that:
    • Text is readable (16px minimum)
    • Buttons are tappable (44px minimum height)
    • Images scale properly
    • Spacing isn’t too tight

Pro tip: Preview every page on your actual phone before publishing.

3. Use Whitespace Generously

Don’t overcrowd your pages:

  • Add padding around text sections (40-60px)
  • Increase line height for better readability (1.5-1.8)
  • Use margin to separate distinct sections (60-100px)
  • Let important elements breathe

Remember: Whitespace makes designs look more expensive and professional.

4. Limit Font Sizes

Too many font sizes create chaos:

  • Headlines: 1-2 sizes maximum
  • Subheadings: 1 size
  • Body text: 1 size (16-18px recommended)
  • Small text: 1 size (14px) for captions and footnotes

5. Test Color Contrast

Ensure text is readable:

  • Dark text on light backgrounds: High contrast for body text
  • Light text on dark backgrounds: High contrast for hero sections
  • Use contrast checkers: WebAIM Contrast Checker (free online tool)
  • Minimum ratio: 4.5:1 for normal text, 3:1 for large text

6. Save Frequently

Protect your work:

  • Click Save Draft often while customizing
  • Use Preview before publishing
  • Create Revisions for easy rollback if needed
