How Can I Achieve Equal Height Headings in Flexbox Items?

Equal Height Headings in Flexbox Items

Flexbox provides a solution for creating a responsive grid layout, ensuring equal height of child elements (.block). However, a specific issue arises when a child element contains a heading (h2) that spans multiple lines, causing a disruption in height equality.

Flexbox and Equal Heights

By default, flexbox applies a property of align-items: stretch to its container, causing child elements to stretch and occupy the full height of the container. This effect is known as "flex equal height columns."

The Challenge

The question arises: is it possible to maintain equal heights for headings (h2) that reside in different child elements? Unfortunately, CSS alone cannot resolve this issue. This is because headings in different containers are not sibling elements and do not inherit equal height properties.

Overriding Flexbox Styles

Equal height settings can be overridden in various ways:

• align-self: This property allows individual elements to override align-items settings.
• Height specification: Manually setting a height on a flex item (e.g., height: 300px) overrides both align-items and align-self.

Limitations of Flexbox

• Equal height columns only apply to child elements of a single flex line within a container.
• In multi-line flex containers, each line establishes its own equal height criteria.
• Flexbox equal height does not apply to cross-container elements, such as headings in different child elements.

Additional Considerations

• Equal height settings in flexbox are applicable only to direct children of a container.
• Equal width columns can be achieved in containers with flex-direction: column.
