Which of the following is not a method for adding a field to the query design grid?
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 the 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 then be explained in greater detail in the rest
of this guide. A grid is a set of intersecting horizontal and vertical lines defining columns and rows. Elements can be placed onto the grid within these column and row lines. CSS grid layout has the following features: You can create a grid with fixed track sizes – using pixels for example. This sets the grid to the specified pixel which fits to the layout you desire. You can also create a grid using flexible sizes with percentages
or with the You can place items into a precise location on the grid using line numbers, names or by targeting an area of the grid. Grid also contains an algorithm to control the placement of items not given an explicit
position on the grid. You can define an explicit grid with grid layout. The Grid Layout specification is flexible enough to add
additional rows and columns when needed. Features such as adding "as many columns that will fit into a container" are included. Grid contains alignment features so we can control how the items align once placed into a grid area, and how the entire
grid is aligned. More than one item can be placed into a grid cell or area and they can partially overlap each other. This layering may then be controlled with the
Grid is a powerful specification that, when combined with other parts of CSS such as flexbox, can help you create layouts that were previously impossible to build in CSS. It all starts by creating a grid in your grid container. We create a grid container by declaring In this example, I have a containing div with a class of wrapper and, inside are five
child elements. I make the
All the direct children are now grid items. In a web browser, you won't see any difference to how these items are displayed before turning them into a grid, as grid has created a single column grid for the items. At this point, you may find it useful to work with the
Grid Inspector, available as part of Firefox's Developer Tools. If you view this example in Firefox and inspect the grid, you will see a small icon next to the value
As you learn and then work with the CSS Grid Layout, this tool will give you a better idea of what is happening with your grids visually. If we want to start making this more grid-like we need to add column tracks. Grid tracksWe define rows and columns on our grid with the
Grid tracks are defined in the
explicit grid by using the Basic exampleI can add to our
earlier example by adding the I have now created a grid with three 200-pixel-wide column tracks. The child items will be laid out on this grid one in each grid cell.
The fr unitTracks can be defined using any length unit. Grid also introduces an additional length unit to help us create flexible grid tracks. The new
Unequal sizesIn this next example, we create a definition with a
Mixing flexible and absolute sizesIn this final example, we mix absolute sized tracks with
Track listings with repeat() notationLarge grids with many tracks can use the
Can also be written as:
Repeat notation can be used for a part of the track listing. In this next
example I have created a grid with an initial 20-pixel track, then a repeating section of 6
Repeat notation takes the track listing, and uses it to create a repeating pattern of tracks. In this next example, my grid will consist of 10 tracks, a
Implicit and explicit gridsWhen creating our example grid we specifically defined our column tracks with the If you place something outside of the defined grid—or due to the amount of content, more grid tracks are needed—then the grid creates rows and columns in the implicit grid. These tracks will be auto-sized by default, resulting in their size being based on the content that is inside them. You can also define a set size for tracks created in the implicit grid with the In the below example, we use
Track sizing and minmaxWhen setting up an explicit grid or defining the sizing for automatically created rows or columns we may want to give tracks a minimum size, but also ensure they expand to fit any content that is added. For example, I may want my rows to never collapse smaller than 100 pixels, but if my content stretches to 300 pixels in height, then I would like the row to stretch to that height. Grid has a solution for this with the
Grid linesIt should be noted that when we define a grid we define the grid tracks, not the lines. Grid then gives us numbered lines to use when positioning items. In our three column, two row grid we have four column lines.
Lines are numbered according to the writing mode of the document. In a left-to-right language, line 1 is on the left-hand side of the grid. In a right-to-left language, it is on the right-hand side of the grid. Lines can also be named, and we will look at how to do this in a later guide in this series. Positioning items against linesWe will be exploring line based placement in full detail in a later article. The following example demonstrates doing this in a simple way. When placing an item, we target the line – rather than the track. In the following example I am placing the first two items on our three column track grid, using the The second item starts on grid column line 1, and spans one track. This is the default so I do not need to specify the end line. It also spans two row tracks from row line 3 to row line 5. The other items will place themselves into empty spaces on the grid.
Note: Don't forget that you can use the Grid Inspector in Firefox Developer Tools to see how the items are positioned against the lines of the grid. Line-positioning shorthandsThe longhand values used above can be compressed onto one line for columns with You can omit the end value if the area only spans one track.
Grid cellsA grid cell is the smallest unit on a grid. Conceptually it is like a table cell. As we saw in our earlier examples, once a grid is defined as a parent the child items will lay themselves out in one cell each of the defined grid. In the below image, I have highlighted the first cell of the grid.
Grid areasItems can span one or more cells both by row or by column, and this creates a grid area. Grid areas must be rectangular – it isn't possible to create an L-shaped area for example. The highlighted grid area spans two row and two column tracks.
GuttersGutters or alleys between grid cells can be created using the
Note: When grid first shipped in browsers the Browsers all now support unprefixed values, however the prefixed versions will be maintained as aliases making them safe to use.
Any space used by gaps will be accounted for before space is assigned to the flexible length Nesting gridsA grid item can become a grid container. In the following example, I have the three-column grid that I created earlier, with our two positioned items. In this case the first item has some sub-items. As these items are not direct children of the grid they do not participate in grid layout and so display in a normal document flow.
Nesting without subgridIf I set
In this case the nested grid has no
relationship to the parent. As you can see in the example it has not inherited the SubgridIn the working draft of the Level 2 Grid specification there is a feature called subgrid, which would let us create nested grids that use the track definition of the parent grid. Note: This feature shipped in Firefox 71, which is currently the only browser to implement subgrid. In the current specification, we would edit the above nested grid example to change the track definition of
Layering items with z-indexGrid items can occupy the same cell, and in this case we can use the Overlapping without z-indexIf we return to our example with items positioned by line number, we can change this to make two items overlap.
The item Controlling the orderWe can control the order in which items stack up by using the

Explore and play with the code examples, and then move on to the next part of this guide, where we will really start to dig into the details of CSS Grid Layout.
