html - Bootstrap row with columns of different height -


i have like:

<div class="row">     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div> </div>

now assuming that, content boxes of different height, same width - how keep same "grid based layout" , yet have boxes line under each other, instead of in perfect lines.

currently twbs place next line of col-md-4 under longest element in previous third row., each row of items aligned clean - while awesome want each item fall directly under last element

this popular bootstrap question, i've updated , expanded answer.

the bootstrap "height problem" occurs because columns use float:left. when column “floated” it’s taken out of normal flow of document. shifted left or right until touches edge of containing box. so, when have uneven column heights, correct behavior stack them closest side.

bootstrap uneven wrapping columns

note: options below applicable column wrapping scenarios there more 12 col units in single .row. readers don't understand why there more 12 cols in row, or think solution "use separate rows" please read first!

there few ways fix this.. (updated 2017)

1 - 'clearfix' approach (recommended bootstrap) (requires iteration every x columns). force wrap every x number of columns...

enter image description here

<div class="row">     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="clearfix"></div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="clearfix"></div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div>     <div class="col-md-4">content</div> </div>

clearfix demo (responsive tiers) - eg. col-sm-6 col-md-4 col-lg-3

there css-only variation of 'clearfix'

2 - make columns same height (using flexbox):

since issue caused difference in height, can make columns equal height across each row. flexbox best way this, , natively supported in bootstrap 4...

enter image description here

.row.display-flex {   display: flex;   flex-wrap: wrap; } .row.display-flex > [class*='col-'] {   display: flex;   flex-direction: column; }

flexbox equal height demo

3 - un-float columns use inline-block instead..

again, height problem occurs because columns floated. option set columns display:inline-block , float:none. provides more flexibility vertical-alignment. however, solution there must no html whitespace between columns, otherwise inline-block elements have additional space , wrap prematurely.

demo of inline block fix

4 - css3 columns approach (masonry-like css solution)..

this not native bootstrap 3, approach using css multi-columns. 1 downside approach column order top-to-bottom instead of left-to-right. bootstrap 4 include type of solution: bootstrap 4 masonry cards demo.

bootstrap 3 multi-columns demo

5 - masonry javascript/jquery approach

finally, may want use plugin such isotope/masonry: enter image description here
