To look after this the Bootstrap framework uses so called columns and breakpoints . In a several words the breakpoints are predefined screen widths at which a shift occurs and the Bootstrap Columns Form become transposed to ideally suit more appropriate. The earlier version applied 4 breakpoints and the most current Bootstrap 4 system offers one extra so they attain in fact five. Here they are along with the highest value they expand to. The correct boundary number in itself refers to the following screen scale.

Extra small up to 34em ( or 544px) – up to Bootstrap 4 Alpha 5 had the -xs- infix. In Bootstrap 4 alpha 6 this infix is dropped so just the number follows;

Small – from 34em up to 48em ( or 768px ) – has the -sm- infix;

Medium – from 48em up to 62em ( or 992px ) – has the -md- infix;

Large – from 62em up to 75em ( 1200px ) - -lg- infix;

Extra large – 75em and everything above it – the new size in Bootstrap 4 – has the -xl- infix.

Later arrives the display dimension infix which in turn identified down to what screen dimension the column feature will span the pointed out quantity of columns. In the case that the display sizing is more compact -- the column component takes up the full screen width-- like it was specified .col-12 (.col-xs-12 up to Bootstrap 4 alpha 5).

Auto layout columns

Employ breakpoint-specific column classes for equal-width columns. Add in any number of unit-less classes for every breakpoint you really need and each Bootstrap Columns Grid will certainly be the equivalent width.

Equivalent width

For example, listed below are two grid layouts that apply to every gadget and viewport, from xs.

<div class="container">
  <div class="row">
    <div class="col">
      1 of 2
    </div>
    <div class="col">
      1 of 2
    </div>
  </div>
  <div class="row">
    <div class="col">
      1 of 3
    </div>
    <div class="col">
      1 of 3
    </div>
    <div class="col">
      1 of 3
    </div>
  </div>
</div>

Placing one column size

Auto-layout for flexbox grid columns likewise signifies you can easily establish the width of one column and the others are going to promptly resize about it.

      3 of 3
    </div>
  </div>
</div>

Variable width web content

Working with the col- breakpoint -auto classes, columns are able to size itself built upon the common size of its content. This is very useful for one line web content like inputs, numbers, etc. This specific, in conjunction with horizontal alignment classes, is really valuable for centralizing formats together with uneven column sizes as viewport width changes.

<div class="container">

    </div>
    <div class="col col-lg-2">
      3 of 3
    </div>
  </div>
</div>

Identical size multi-row

Establish equal-width columns that extend multiple rows by simply filling in a .w-100 specifically where you prefer the columns to break to a new line. Help make the divisions responsive simply by putting together the .w-100 with some responsive display screen utilities.

<div class="row">
  <div class="col">col</div>
  <div class="col">col</div>
  <div class="w-100"></div>
  <div class="col">col</div>
  <div class="col">col</div>
</div>
