Grid layout introduces the two-dimensional grid system. In other words the Grid layout system works with columns and rows as opposed to the one dimensional alternatives which let us work with either the columns or the rows.

This is really important because with this layout system we can build more complex layouts in a simple and clean way. To be more specific, we don’t have to include everything in the html markup as we would do with other tools like Bootstrap for example.

Now let’s see some practical tips to help us use Grid in our layouts.

Grid Tips

  1. Draw your grid first on paper.

    • It really helps you have a visual representation of what you are trying to achieve.
  2. Be cautious when using fractions.

    • Grid offers a powerful feature to set widths as fractions of the available space. However, if you mix fractions and non-flexible spacing, such as pixels, fractions are calculated based on the space remaining after the fixed width elements are accounted for. This can mean the grid doesn’t end up looking how you pictured it.
  3. Be cautious with whitespace.

    • If your layout includes any rows or columns with no elements, you need to account for this whitespace too. Be sure to account for empty contents as much as elements.
  4. Understand how explicit and implicit grids are formed.

    • Understanding how Grid forms these will really help you set up your grid properly and avoid unexpected results.
  5. Start with a simple grid.

    • Setup a simple grid and make small adjustments. If you create a grid with an even number of columns and rows it will limit the flexibility of the grid but while learning will help avoid any confusion.

Unfortunately there is one limitation to the current grid specification. This limitation is that subgrids are not yet widely available. According to the CSS specification, subgrid is defined as a nested grid that follows the same grid as the parent. Currently only Firefox supports these, and there is no current schedule for when other browsers will implement subgrids.

Having said that all major browsers support Grid and that means that you can use it right away to start creating awesome layouts. You can find out if your browser version supports it here.
