How Can I Achieve Equal Height for H2 Headings Across Multiple Flex Containers Using CSS?

Equal Height Children of Flex Items

In this instance, you're aiming to achieve equal height for all .block divs, ensuring that the .bottom div remains absolutely positioned at the bottom. While this is achievable through the current solution, you encounter an issue when h2 headings exceed a single line. To address this, you desire equal height for h2 headings within each row.

However, it's important to note that this specific requirement is not possible to achieve solely using flexbox or CSS in general.

Flexbox Equal Height Columns

Flexbox provides the align-items: stretch property by default, which causes flex items to expand the full height of the cross axis. This is known as "flex equal height columns."

Key Notes:

• Equal height columns apply only to children of a single flex container, meaning the flex items must share the same parent for this feature to work.
• Equal height columns apply to items on a single flex line. For multi-line flex containers, each line establishes its own equal height distribution.
• Individual flex items can override the align-items property using align-self, breaking the equal height feature.
• Specifying a height on a flex item overrides both align-items and align-self, ignoring the equal height setting.

Why Equal Height for Headings is Not Possible

CSS cannot implement equal height for h2 headings across different containers because these headings are not siblings within the flex container. Headings in different containers are considered "cousins" rather than siblings, and the equal height feature does not extend beyond siblings.

Conclusion

While flexbox provides powerful options for aligning and sizing content, it's limited in its ability to enforce equal height across elements that are not direct siblings. In this specific case, achieving equal height for h2 headings in different containers requires exploring alternative methods that lie outside the scope of pure CSS and flexbox.
