Mastering the Art of Flex Containers in WordPress 6.3 Block Editor

In the realm of the WordPress 6.3 Block Editor, understanding flex containers and their settings can significantly streamline your site design process. Flex containers are versatile, allowing for diverse layouts that adapt seamlessly to various screen sizes.

What Are Flex Containers?

Flex containers, deriving from the CSS Flexbox module, enable you to design complex layout structures with a cleaner design logic than float or tables. The WordPress block editor has adopted this model, introducing blocks that utilize flex principles.

Full Width & Wide Width

Full Width: This setting allows a block to span the entire width of the viewport. It’s useful when you want a background color, image, or pattern to extend edge-to-edge.

Wide Width: Provides a wider design than the default width, but doesn’t span the entire viewport. It’s a middle ground between standard and full width.

Horizontal Alignment: Left, Center, Right

This determines the alignment of blocks within a container:

Left: Aligns content to the left.
Center: Centers content.
Right: Aligns content to the right.

Vertical Alignment: Top, Middle, Bottom

This specifies the vertical placement of content within a flex container:

Top: Positions content at the top.
Middle: Centers content vertically.
Bottom: Anchors content at the bottom.

Flex Spacing

Flex spacing is all about distributing space among items within a flex container:

Space-between: Places equal spacing between each item.
Space-around: Distributes space around items, half on either side.
Space-evenly: Equal spacing around and between items.

Nesting Containers

Nesting allows you to place a container within another container. It provides granular control over the design:

Outer Container defines the overarching layout.
Inner Container can have its unique properties.

Remember, the properties of the outer container may influence the available settings for the inner container.

What affects whether an element is full screen-width vs the width of the containing element?

The width of an element in a web page, especially in WordPress, can be influenced by several factors:

Theme Restrictions: Your chosen theme might have default widths set for content. Some themes restrict content to a certain width to maintain a particular design aesthetic.
Block Settings: In the WordPress block editor, blocks like Group, Cover, and Column have width settings such as wide width and full width. If you set a block to full width, it’ll stretch across the entire width of the viewport.
CSS Styling: Custom CSS can be used to override default widths. Using properties like width, max-width, and min-width can define specific measurements.
Parent Container: If an element is inside a container (like a Group block in WordPress), the width of the parent container can limit the element’s width. For example, if the container has a maximum width set, all child elements within it will be restricted to that width.

When do you put a “regular block” (such as heading and paragraphs) inside a container within a container, vs just using a single container?

Using nested containers (a container inside another container) or a single container depends on the design complexity and functionality you’re aiming for:

For Basic Designs: If you’re looking to apply a basic background color, border, or spacing around a heading and paragraph, a single container would suffice.
For Complex Designs: Suppose you want to have a section with a distinct background color and within that, you want a heading and paragraph to have their own separate background, spacing, or border. In this scenario, you’d nest the heading and paragraph inside a container, and then place that container inside another container with the distinct background color.
For Advanced Layouts: Nested containers can help achieve complex layouts like grids with unique styles within each grid cell.

What flex container settings interfere with other container settings? What is the right way to get different container layouts?

Flexbox is a versatile layout model, but some settings can interfere or override others:

Flex Direction vs. Flex Wrap: flex-direction defines the direction of the flex items (row or column). If you have flex-wrap set to wrap and there’s not enough space for items to fit in a single line, they’ll move to the next line. This might change the appearance if you initially planned for all items in one line.
Justify-content vs. Align-items: justify-content arranges items horizontally while align-items does so vertically. If you change the flex-direction, the roles of these properties will swap, which can be confusing.
Flex-grow, Flex-shrink, and Flex-basis: These properties define how items grow and shrink within a flex container. If not used correctly, they can cause items to overlap or take up more space than anticipated.

The Right Way to Get Different Container Layouts:

Plan Ahead: Before diving into designing, sketch out or note down the layout you want.
Use Developer Tools: If you’re unsure of how certain flex properties are affecting your layout, use browser developer tools to inspect elements. This allows you to see and experiment with applied styles.
Start Basic: Begin with basic settings, and then add complexity. For instance, start by setting the flex-direction and then adjust alignment, wrapping, and individual item properties.
Practice: Like all design tools, mastering flex containers in WordPress or any platform comes with practice. Experiment with different settings to understand their behavior and interactions.

Remember, while flexbox is powerful, it might not always be the solution. Depending on your layout needs, consider other CSS layout models like Grid or traditional block and inline display properties.

Setting Flexbox Widths and Heights

Setting element widths in a flexbox layout is integral to achieving a desired design. You can use various methods, depending on the specific look and functionality you aim for.

1. Setting Element Widths in Flexbox:

Pixel Widths (px):

Offers fixed-width columns regardless of the viewport size.
Can be problematic for responsive design since the width remains constant across devices.
You should rarely (if ever) use pixel widths in a Flexbox design.

Percentage Widths (%):

More responsive than pixel widths.
The columns adjust based on the percentage of the parent container’s width.
Since CSS can do simple calculations, you can specify widths as (100% / number of columns) to split evenly, e.g., 100% / 3 for 3 columns.

Flexbox Relative Widths (flex):

Uses the flex property, which is a shorthand for flex-grow, flex-shrink, and flex-basis.
The default value is flex: 0 1 auto, which means columns don’t grow beyond their content width, can shrink, and have an initial width based on content.
For equal-width columns, you can use flex: 1 which ensures that all columns take up an equal amount of available space.
To make one column twice as wide as the others, or more accurately “grow wider twice as fast”, you can use flex: 2 for that particular column and flex: 1 for the others.

2. Balancing Column Heights:

Flexbox’s primary strength is its ability to align content vertically, making it easier to balance column heights. However, equal height columns do not guarantee equal content length due to variations in content density (e.g., text, images). Here’s how you can approach it:

Equal Height Columns:

By default, flexbox child elements (flex items) will be the same height in a row. They stretch to the height of the tallest item.

Balancing Content for Approximately Equal Heights:

This requires more strategic content planning rather than a pure CSS solution.
Aim for a balanced amount of content in each column.
Utilize content strategies like trimming text, using excerpts, or using CSS media queries to adjust font sizes for different devices to ensure uniformity.

Row Wrapping:

If you have a multi-row flex container and want each row’s items to align to that row’s height instead of the tallest item in the entire container, you should separate your flex containers row-by-row.

Example CSS of a 3-Column Flexbox:

.container {
    display: flex;
    justify-content: space-between;
}

.column {
    flex: 1; /* Equal width */
    padding: 10px;
    box-sizing: border-box;
}

/* Optional: For a column to be twice as wide */
.wider-column {
    flex: 2;
}

This CSS gives you a 3-column layout where each column adjusts to the container’s width. The .wider-column class allows one column to take up additional space twice as fast compared to the others.

Making 3-column Layouts Using Flexbox

1. Creating a 3-Column Flexbox using Block Editor:

Add a Columns Block:
- In your post or page editor, click the “+” button to add a new block.
- Search for and select the “Columns” block.
- Choose the “Three columns” layout from the patterns that appear.
Adjust Column Widths:
- By default, each column in the “Columns” block will have an equal width.
- To adjust individual column widths, click on the particular column you want to modify.
- In the Block settings panel on the right, there’s a “Percentage width” slider (or a width setting). Adjust the width of the columns as desired.
Add Content to Columns:
- Click inside each column to add blocks like “Paragraph”, “Image”, “Heading”, etc.
- Add your content into these blocks.

2. Applying Custom CSS like “flex: 2;” in the Block Editor:

Add a Columns Block:
- If you haven’t already, follow the steps above to add a 3-column layout.
Use the Advanced Panel for Custom CSS:
- Click on the column you wish to apply the custom CSS to.
- In the Block settings panel on the right, scroll down to the “Advanced” section.
- There’s a field labeled “Additional CSS class(es).” Here you can add a custom class, say, wider-column .
Add Custom CSS in the Customizer:
- Go to Appearance > Customize from your WordPress dashboard.
- Navigate to Additional CSS.
- Add your custom CSS, e.g.,
Publish your changes.

By following the above steps, you have successfully applied a flex: 2; style to the desired column, making it grow wider twice as wide as the other columns.

Note: While the Block Editor provides a robust set of tools for designing layouts, sometimes it’s more efficient and offers greater flexibility to use a combination of Block Editor features and custom CSS for advanced styling needs.

In conclusion, the method you choose for setting widths in a flexbox layout depends on your design goals. For most use cases, using the flex property offers the greatest flexibility and responsiveness. Balancing content visually is a mix of CSS techniques and content curation.
