Component 3: Auto-flow, Order as well as Thing Positioning

When it pertains to developing a design, CSS Grid provides us a variety of various selections for putting products. In this short article we’ll have a look at the various positioning techniques, exactly how to make use of auto-flow to stay clear of needing to clearly put every thing, as well as why often grid products may not be put where you anticipate them to be.

I such as to think about making use of Grid as 2 distinctive components:

  1. Scaffolding– or developing the framework of the grid itself. This entails specifying the residential properties acting upon the grid container, starting with display screen: grid, as well as defining the form of the grid as well as exactly how it ought to act making use of any kind of mix of grid-template-columns, grid-template-rows, grid-auto-columns as well as grid-auto-rows (or grid/ grid-template if making use of the shorthand).
  2. Providing the grid– informing the internet browser where each youngster of our grid container ought to be put.

In this short article we’ll take a much deeper consider the 2nd component, as well as specifically automobile positioning.

Various methods to put a grid thing

Specific positioning

The residential properties that permit us to clearly put products on a grid are:

  • grid-column-start
  • grid-column-end
  • grid-row-start
  • grid-row-end
  • grid-column (shorthand for grid-column-start/ grid-column-end)
  • grid-row (shorthand for grid-row-start/ grid-row-end)
  • grid-area (shorthand for grid-row-start/ grid-column-start/ grid-row-end/ grid-column-end)

The over residential properties are specified on the products themselves. Feasible worths consist of line numbers, line names, period worths or location names. There are no policies for which you ought to as well as should not make use of, as well as you can blend as well as match as you such as. As an example:

 thing-- a  {
grid-area: a;

thing-- b {
grid-area: 2/ 2/ 4/ 4;

thing-- c {
grid-row: period 2/ 5;
grid-column: 1/ 3;


In Addition, we have grid-template-areas This home it is specified on the grid container It enables us to specify grid locations with names, after that recommendation those locations to put the products:

 grid  {
display screen: grid;
grid-template-columns: repeat( 3, 1fr);
grid-template-rows: repeat( 4, 120px);
' a a a'
'. b b'
'. b b'
' ...';

a {
grid-area: a;

b {
grid-area: b;

This is quite great, as it suggests we can transform the format dramatically by just changing the grid-template-areas worth. We do not require to include or transform any kind of residential properties on the products themselves. A big win for receptive layout!

We could be lured to put every thing clearly making use of grid-template-areas However there’s one disadvantage: You can not specify overlapping locations. Developing a design like Fig 01 can not be made with grid-template-areas alone.

A grid with three items
Fig 01 Products 2 as well as 3 overlap, so just one can have its location specified by ‘grid-template-areas’.

However we can usage grid-template-areas additionally to putting products by line name or location.

 a  {
grid-area: a;

b {
grid-area: b;

c {
grid-area: 3/ 1/ 5/ 3;

Vehicle positioning

If we do not explicity area products on our grid, they will certainly be auto-placed. By default each grid products have a period of 1 on both the row as well as the column axis, so they will certainly each be put right into the following readily available grid cell. We can utilize this to our benefit: If we have something like an information feed, we do not wish to need to put each thing clearly, particularly if we do not understand the number of products there will certainly be.

Auto placement
Fig 02 No products are explicity put, for that reason they are all automobile put.

Anticipating automobile positioning

In the above instance the policies of automobile positioning are rather instinctive: Products are put along the row (or inline) axis till they fill the row, and after that they’ll cover onto the following row (developing a brand-new row if there isn’t one specified).

However if we have some products that are explicity put, as well as others that are not, them exactly how can we determine the cells the automobile put be put right into?

If I put a product on my grid making use of grid-column: 2/ period 2 I may anticipate that any kind of automobile put products being successful that a person will certainly be put after the one I’m putting ( Fig 03):

Three grid items with a mixture of explicit and auto placement
Fig 03 Heaven thing is clearly put on the row as well as column axis (making use of ‘grid-template-columns’ as well as grid-template-columns’).

What in fact occurs with the above code is the being successful products are put prior to the put thing. They are put right into the very first readily available cells, which take place to be the very first 2 in our grid.

Three grid items with a mixture of explicit and auto placement
Fig 04 Heaven thing is clearly put just on the column axis (making use of grid-template-columns’).

However if we put heaven thing just on the column axis, the products are put after the very first one:

Three grid items with a mixture of explicit and auto placement
Fig 05 Heaven thing is put on the column axis with ‘grid-column: 2/ 4’.

So why is the positioning behavior various? If we recognize the policies of automobile positioning, points come to be more clear.

Recognizing circulation

A great way to think of this is to think about our grid as a moving river. Any type of clearly put products are watercrafts secured in the river. Vehicle put products move around these, from delegated right ( Fig 06).

Grid items with a mixture of explicit and auto placement
Fig 06

Grid products that are just clearly put on one axis are a lot more loosly secured. They join the grid circulation on the staying axis.

Products put making use of a period worth alone will certainly still move like the others, yet they’ll be limited by their very own specific dimension. A product with a period of 2 will certainly move onto the following row if there are much less than 2 grid columns readily available. We can think about these as being semi-auto put ( Fig 07).

Grid items with a mixture of explicit and auto placement
Fig 07 Thing 2 has a column period of 3, so will certainly cover onto the following line.

In Fig 07 we’re just putting the thing on the column axis once again (making use of period), so succeeding products are put after it. We have sufficient products to load the grid precisely– yet as opposed to filling up earlier grid cell, the 6th as well as 7th products develop an implied track. This does not take place if we just put it clearly on the row axis ( Fig 08).

Auto placed items filling up the explicit grid
Fig 08 Thing 2 has a row period of 3

This is to do with the order in which thing positioning is solved in the grid positioning formula

Altering the circulation of your grid

There are 2 various residential properties we can make use of to scuff of products in the grid. The very first is grid-auto-flow This alters the instructions of circulation, as well as for that reason exactly how products will certainly be automobile put. Feasible worths are row (default), column, row thick as well as column thick

grid-auto-flow: column

By transforming the worth from row to column, we can see in the 2nd area in this trial that the behavior has actually currently turned around: Products put on the column axis are currently solved in advance of those on the row axis. Positioning a product on the column axis no more creates an implied grid track, as products are loaded right into every cell, yet putting a product on the row axis does

grid-auto-flow: thick

Utilizing the thick key phrase along with row or column ( row is the default), we can.
define that automobile put products ought to load themselves right into any kind of readily available grid cells (consisting of ones preceeding any kind of clearly put products). This will certainly make sure there are no spaces, also if a product is put on just one axis. In the above trial you can see exactly how each of the worths for grid-auto-flow change the behavior of the grid.


The order home is not unique to Grid– it can additionally be utilized with flexbox. It enables us to scuff of private products within the circulation. Products have a default order of 0. Altering a vehicle put thing’s order to -1 will certainly put it at the beginning of the grid automobile put grid products– after clearly put products, if there are any kind of put at the beginning of the grid.

The order home will just impact automobile as well as semi-auto put products (those making use of a solitary period worth). In the trial listed below the purple thing’s setting is modified making use of the order home, yet heaven thing, which is clearly put, is not influenced.

You may have discovered, grid-auto-flow enables us to transform the instructions of circulation from row to column, yet it does not permit us to make products circulation from right to left. Rather, we can make use of the instructions home. This becomes part of the CSS Creating Settings, which is developed to sustain global composing settings where message moves in a various instructions from left-to-right. To make our grid circulation from right to left we can utilize this:

 grid  {
instructions: rtl;

⚠ Usage with care ⚠

Qualities that impact the aesthetic order of grid products ought to be utilized with miraculous care, as the do not transform the resource order, as well as can for that reason negatively impact access. Rachel Andrew has actually composed thoroughly regarding it in her short article, Grid, material re-ordering as well as access

I think there are some situations where aesthetic re-ordering makes good sense, yet in my experience they usually include specific thing positioning.


I wish this short article has actually assisted debunk some concerns around positioning of automobile circulation grid products. You may additionally be interested to check out component 1 of this collection, Recognizing Implicit Tracks, which additionally handles positioning of grid products.
