Responsive layout grid

Proximus responsive layout grid adapts to screen size and orientation, ensuring consistency across layouts.

The grid is mobile-first and fundamental to everything we design. The gridding is the geometric foundation of all the visual elements of Proximus UI, from typography to columns, boxes, icons, and illustrations. It provides structure and guidance for all creative decision-making.

Anatomy

The layout grid is made up of three elements: columns, gutters, and margins.

Columns
Content is placed in the areas of the screen that contain columns.
Default gutters
Gutters are the spaces between columns. They help separate content. Gutters are present by default and identical amongst all breakpoints. For closely related content, the grid gutters can be collapsed.
Margins
Margins are the space between content and the left and right edges of the screen. Margin widths are defined as a fixed value for all the breakpoint.

Expanded grid

In some specific cases, we can used bigger gutters. With the expanded grid, gutters and columns have different values than the default one for medium up, margins remain the same.

Basic

Start by adding an element with a class of row. This will create a horizontal block to contain vertical columns. Then add divs with a columns class within that row. You can use column or columns - the only difference is grammar. Specify the widths of each column with the small-#, medium-#, and large-# classes.

Foundation is mobile-first. Code for small screens first, and larger devices will inherit those styles. Customize for larger screens as necessary (Show-for-medium is better than hide-for-small).

Info

To avoid misunderstandings, we decided to make mandatory the definition of small sizes even for small-12.

Nesting

You can nest the grids indefinitely, though at a certain point it will get absurd.

Incomplete Rows

In order to work around browsers' different rounding behaviors, Foundation will float the last column in a row to the right so the edge aligns (yes, it means the last column is not perfectly the same 1/12th). If your row doesn't have a count that adds up to 12 columns, you can tag the last column with a class of end in order to override that behavior.

Offsets

Move blocks up to 11 columns to the right by using classes like .large-offset-1 and .small-offset-3

10, offset 1

Collapse rows

The Zurb Foundation collapse class lets you remove column gutters (padding).

To collapse row columns gutters per breakpoint, you can use following rslib classes classes:

rs-collapse-for-small-only
rs-collapse-for-medium-only
rs-collapse-for-medium-up
rs-collapse-for-large-up

Gutter Removed

Centered columns

Center your columns by adding a class of small-centered to your column. Large will inherit small centering by default, but you can also center only on large by applying a large-centered class. To uncenter on large screens use large-uncentered.

Centered/uncentered classes are off course available for all device sizes.

3 centered

6 centered large

9 large uncentered

11 centered

Push/pulls

Using these source ordering classes, you can shift columns around between our breakpoints. This means if you place sub-navigation below main content on small displays, you have the option to position the sub-navigation on either the left or right of the page for large displays. Prefix push/pull with the size of the device you want to apply the styles to. medium-push-#, large-push-# is the syntax you'll use. Use large-reset-order to reset pushed or pulled columns to their original position on large screens.

Expanded gridding (larger gutters)

To allow bigger gutters between columns in a row, you can add rs-xpandgrid to <div class="row">

Lorem ipsum

Auto/Last

Using the classes rs-auto and rs-last, you can collapse the first column to the content and use the remaining space to the second column.

the remaining space

Auto/Last (flex shrink code)

Using the classes rs-flex-row, rs-flex-column and rs-flex-shrink, you can collapse one column to the content and use the remaining space to the other column.

rs-flex-column without "s"

Flex column class for auto/last gridding is rs-flex-column without "s".
rs-flex-columns with "s" is used for classic flex gridding with small-12, medium-6,... sizes classes.

shrunk column

Flex shrink/grow per breakpoint

You may also need a flex shrink or grow (to force an element to fill up the remaining space) for a specific device, you can use following classes per breakpoint:

	Small only	Small up	Medium only	Medium up	Large only	Large up
Shrink	`rs-flex-shrink-small-only`	`rs-flex-shrink`	`rs-flex-shrink-medium-only`	`rs-flex-shrink-medium`	`rs-flex-shrink-large-only`	`rs-flex-shrink-large`
Grow	`rs-flex-grow-small-only`	`rs-flex-grow`	`rs-flex-grow-medium-only`	`rs-flex-grow-medium`	`rs-flex-grow-large-only`	`rs-flex-grow-large`

Flex gridding

Flex gridding is a variant of traditional gridding. The difference is the usage of css flex properties instead of left or right float position.

To use flex gridding, the only things to do is use:

rs-flex-row instead of row
rs-flex-columns instead of columns
All sizes classes ( small-12, medium-12, large-12,... remain unchanged

rs-flex-columns with "s"

Flex column class is rs-flex-columns with "s".
rs-flex-column without "s" is used for auto/last flex gridding .

Collapse flex rows

rs-flex-collapse class lets you remove flex column gutters (padding).

To collapse flex row columns gutters per breakpoint, you can use following rslib classes classes:

rs-flex-collapse-for-small-only
rs-flex-collapse-for-medium-only
rs-flex-collapse-for-medium-up
rs-flex-collapse-for-large-up

Gutter Removed

Expanded flex gridding (larger gutters)

To allow bigger gutters between flex columns in a flex row, you can add rs-xpandgrid to <div class="rs-flex-row"> .

Info

An expanded flex grid should be nested in a grid to work properly.

Lorem ipsum

Flex order (push/pull)

You can change the order of flex columns per breakpoint with following classes:

rs-order-sX
rs-order-mX
rs-order-lX

(X is a number between 1 and 10 included.)
Columns will be sorted by ascending number. If you put no order class, it means the position is 0 so this content will be displayed first.

Horizontal alignment for flex elements

To align along the main axis, you can use following classes:

Breakpoint	Align Left	Align Right	Align center	Space between
Small up	`rs-justify-left`	`rs-justify-right`	`rs-justify-center`	`rs-justify-between`
Small only	`rs-justify-left-small-only`	`rs-justify-right-small-only`	`rs-justify-center-small-only`	`rs-justify-between-small-only`
Medium up	`rs-justify-left-medium`	`rs-justify-right-medium`	`rs-justify-center-medium`	`rs-justify-between-medium`
Medium only				`rs-justify-between-medium-only`
Large up	`rs-justify-left-large`	`rs-justify-right-large`	`rs-justify-center-large`	`rs-justify-between-large`
Large only				`rs-justify-between-large-only`

Vertical alignment for flex elements

To align along the cross axis, you can use following classes:

Breakpoint	Align Top	Align Bottom	Align middle
Small up	`rs-flex-top`	`rs-flex-bottom`	`rs-flex-middle`
Small only	`rs-flex-top-small-only`	`rs-flex-bottom-small-only`	`rs-flex-middle-small-only`
Medium up	`rs-flex-top-medium`	`rs-flex-bottom-medium`	`rs-flex-middle-medium`
Medium only	`rs-flex-top-medium-only`	`rs-flex-bottom-medium-only`	`rs-flex-middle-medium-only`
Large up	`rs-flex-top-large`	`rs-flex-bottom-large`	`rs-flex-middle-large`
Large only	`rs-flex-top-large-only`	`rs-flex-bottom-large-only`	`rs-flex-middle-large-only`

Flex direction

By default, content is aligned horizontally. You could change direction to vertical by using .rs-flex-dir-col to your row or flex element.
It can also be done per breakpoint with following classes:

Small up	`rs-flex-dir-col`
Small only	`rs-flex-dir-col-small-only`
Medium up	`rs-flex-dir-col-medium`
Medium only	`rs-flex-dir-col-medium-only`

Flex no wrap

To force all flex items to be on one line per breapoint, you can use following classes:

Small only	`rs-flex-nowrap-small-only`
Medium up	`rs-flex-nowrap-medium`
Medium only	`rs-flex-nowrap-medium-only`
large up	`rs-flex-nowrap-large`
large only	`rs-flex-nowrap-large-only`

Flex utility classes

`rs-flex`	To transform an element to a flex element (display: flex;). To avoid issue with IE, you need to combine `rs-flex` with `rs-maxw`
`rs-flex-row-wrap`	To transform an element to a flex element (display: flex;) and make its children go one next to the other and wrap onto multiple lines (flex-flow: row wrap;)
`rs-flex-auto`	To make a flex item grow or shrink to fit the space available in its flex container (flex: auto or flex: 1 1 auto;)
`rs-flex-inline`	To make a flex container display inline (display: inline-flex;)
`rs-flex-dir-row-small-only`	To make flex items be one next to to other in the flex container on mobile only (flex-direction: row;)
