CSS Grid layout excels at dividing a page into major regions, or defining the relationship in terms of size, position, and layer, between parts of a control built from HTML primitives. | ||
336 | Auto-placement in CSS Grid Layout | CSS, CSS Grids, Guides |
In addition to the ability to place items accurately onto a created grid, the CSS Grid Layout specification contains rules that control what happens when you create a grid and do not place some or all of the child items. You can see auto-placement in action in the simplest of ways by creating a grid on a set of items. If you give the items no placement information they will position themselves on the grid, one in each grid cell. | ||
337 | Basic concepts of grid layout | CSS, CSS Grids, Guide, Layout |
CSS Grid Layout introduces a two-dimensional grid system to CSS. Grids can be used to lay out major page areas or small user interface elements. This article introduces CSS Grid Layout and the new terminology that is part of the CSS Grid Layout Level 1 specification. The features shown in this overview will be then explained in greater detail in the rest of this guide. | ||
338 | Box alignment in CSS Grid Layout | CSS, CSS Grid, Guides |
If you are familiar with flexbox then you will already have encountered the way in which flex items can be properly aligned inside the flex container. These alignment properties that we first met in the flexbox specification have been moved into a new specification called Box Alignment Level 3. This specification has details for how alignment should work in all of the different layout methods. | ||
339 | CSS Grid Layout and Accessibility | Accessibility, CSS, CSS Grids, Guides |
Those of us who have been doing web development for more years than we care to remember might consider that CSS Grid is a little bit like using “tables for layout”. Back in the early days of web design, the way we constructed page layout was to use HTML tables, then fragment our design into the cells of those tables in order to create a layout. This had some advantages over the “CSS Positioning” that came afterwards, in that we could take advantage of the alignment and full height columns offered by table display. The biggest downside however was that it tied our design to the mark-up, often creating accessibility issues as it did so. In order to lay the design out in the table we often broke up the content in ways that made no sense at all when read out by a screen reader for example. | ||
340 | CSS Grid Layout and Progressive Enhancement | CSS, CSS Grids, Design, Guide, Intermediate |
we should shortly have CSS Grid Layout support in the public versions of Firefox, Chrome, Opera and Safari. However, while evergreen browsers mean that many of us are going to see the majority of users having Grid Layout support very quickly, there are also old or non-supporting browsers to contend with. In this guide we will walk through a variety of strategies for support. | ||
341 | CSS grids, logical values and writing modes | CSS, CSS Grids, Guides |
For this guide, we will look at this feature of grid and other modern layout methods, learning a little about writing modes and logical versus physical properties as we do so. | ||
342 | Grid template areas | CSS, CSS Grids, Guide |
In the previous guide we looked at grid lines, and how to position items against those lines. When you use CSS Grid Layout you always have lines, and this can be a straightforward way to place items on your grid. However, there is an alternate method to use for positioning items on the grid which you can use alone or in combination with line-based placement. This method involves placing our items using named template areas, and we will find out exactly how this method works. You will see very quickly why we sometimes call this the ascii-art method of grid layout! | ||
343 | Layout using named grid lines | CSS, CSS Grids, Guide |
In previous guides we’ve looked at placing items by the lines created by defining grid tracks and also how to place items using named template areas. In this guide we are going to look at how these two things work together when we use named lines. Line naming is incredibly useful, but some of the more baffling looking grid syntax comes from this combination of names and track sizes. Once you work through some examples it should become clearer and easier to work with. | ||
344 | Line-based placement with CSS Grid | CSS, CSS Grids, Guide |
In the article covering the basic concepts of grid layout, we started to look at how to position items on a grid using line numbers. In this article we will fully explore how this fundamental feature of the specification works. | ||
345 | Realizing common layouts using CSS Grid Layout | CSS, CSS Grids, Guides |
To round off this set of guides to CSS Grid Layout, I am going to walk through a few different layouts, which demonstrate some of the different techniques you can use when designing with grid layout. We will look at an example using grid-template-areas, a typical 12-column flexible grid system, and also a product listing using auto-placement. As you can see from this set of examples, there is often more than one way to achieve the result you want with grid layout. Choose the method you find most helpful for the problems that you are solving and the designs that you need to implement. | ||
346 | Relationship of grid layout to other layout methods | CSS, CSS Grids, Guide |
CSS Grid Layout has been designed to work alongside other parts of CSS, as part of a complete system for doing layout. In this guide I will explain how a grid fits together with other techniques you may already be using. | ||

Let's start with a basic example. In the root stacking context we have two DIVs (DIV #1 and DIV #3), both relatively positioned, but without z-index properties. Inside DIV #1 there is an absolutely positioned DIV #2, while in DIV #3 there is an absolutely positioned DIV #4, both without z-index properties. | ||
363 | Stacking context example 2 | Advanced, CSS, Understanding_CSS_z-index |
This is a very simple example, but it is the key for understanding the concept of stacking context. There are the same four DIVs of the previous example, but now z-index properties are assigned on both levels of the hierarchy. | ||
