Which is 2.4 columns wide: let’s call it col-2dot4 (and col-sm-2dot4, col-md-2dot4, …).Įach column should eat 20% of the available space ( 100 / 5 = 20): that’s easy. Let’s stick to the example of 5 columns per row. Good news, this is possible: you just need a few custom CSS rules. It some cases, one wants/needs to fit, for instance, 5 equal-width columns in a row, and to have them take all the available Note: I know one could use the CSS grid now, but this article is about Bootstrap. Number of same-width columns per row which is not a divisor of 12. Its grid system is very well crafted, but it doesn’t allow to have a Justify-content for horizontal or vertical alignment (centering, bottom, right, etc.).Bootstrap is an awesome toolkit when it comes to build responsive web pages that workĪcross different browsers with little effort. Use auto-margins or Flexbox align-items and

This typical 2 column page layout is where we can see the most common use. Rows are display:flex, and therefore Columns are equal height in the same row. Bootstrap 3s responsive grid is powerful, but getting columns to stack nicely. Therefore, you only need to use the class for the smallest width you want to support. The smaller grid classes also apply to larger screens unless overridden specifically for larger screen width. Use a specific col-* to prevent that vertical stacking. Specific col-* class in your HTML markup. Key points on Responsive Design using the Grid:Ĭolumns will stack vertically (and become full-width) at the smaller screen widths unless you use a The sidebar will stack on top at the sm breakpoint of 576px: The right column will automatically grow to fill the width. Here’s an example of combining the classic defined-width columns, Remember, you can switch out sm for whatever breakpoint (md,lg,xl) is needed.Ģ columns, left sidebar & right. In this example, the `cols` remain horizontal until the sm breakpoint of 576px, and then stack vertically: The `cols` remain horizontal at all widths, and don’t stack vertically because the xs breakpoint is the default:ģ equal-width columns (responsive). Take a look at a few auto-layout Grid examples…ģ equal-width columns. But, don’t forget, the 12-unit columns can be mixed-in as needed. The auto-layout columns are perfect for any layout scenarios where equal-width columns are required.

The 2nd segment of the class name tell us the screen size. Because of their simplicity, I prefer them over the classic 12-unit columns. So the column width is determined depedning on which col-xx-x class we are using. The Bootstrap 4 auto-layout columns also work responsively. For example:įor a different column width on a larger tier, use the appropriate larger breakpoint to override the smaller breakpoint.įor example, 3 columns wide on sm, and 4 columns wide on md-and-up: For the same column width on all tiers, just set the width for the smallest tier that’s desired.

Therefore, col-sm-6 really means 50% width on small-and-up. Or, in reverse… xl > overrides lg > overrides md > overrides sm > overrides (xs) Larger breakpoints, override Smaller breakpoints. Since (xs) is the default breakpoint, the col-12 is implied. Below 767px viewports, the columns become fluid and stack vertically. With the responsive CSS file added, the grid adapts to be 724px and 1170px wide depending on your viewport. Since I didn’t specify a default Column width, the 50% width was only applied on 768px and wider for the sm breakpoint. The default Bootstrap grid system utilizes 12 columns, making for a 940px wide container without responsive features enabled. This is because (xs) is the default or implied breakpoint. On less than 768px, the 2 columns become 100% width and stack vertically: The col-sm-6 means use 6 of 12 columns wide (50%), on a typical small device width (greater than or equal to 768 px): This will effectively show two columns for screen resolution greater than 768px. In the following example I have used col-sm-6 for each column. They enable you to control Column behavior at different screen widths.įor example: here are 2 columns, each 50% width: Answer (1 of 2): You can build a two column layout easily using bootstrap grid layout columns. So instead ofīootstrap uses CSS media queries to establish these Responsive Breakpoints. Why did I put (xs) in parenthesis, and not the other breakpoints? Since xs (extra-small) is the defaultīreakpoint, the -xs infix that was used for Bootstrap 3.x is longer used in Bootstrap 4.x.
