php - Bootstrap row element based on breakpoint -


i'm using bootstrap , looping div - because bootstrap requires parent div 'row' class, need print row based on number of divs within that. problem is, examples can find set number, , need based on breakpoint. example, code is:

<div class="row">      <?php foreach($projects $project): ?>        <div class="col-lg-4 col-md-6 col-sm-12 project_box">          <a href="<?= $project->url() ?>" class="project_name"><?= $project->title()->html() ?></a>            <?php if($image = $project->images()->sortby('sort', 'asc')->first()): $thumb = $image->crop(600, 600); ?>              <a href="<?= $project->url() ?>"><img src="<?= $thumb->url() ?>" alt="thumbnail <?= $project->title()->html() ?>" class="responsive" /></a>            <?php endif ?>            <p class="summary">              <?php echo excerpt($project->problem(), 200) ?>            </p>          </a>          <a href="<?= $project->url() ?>" class="btn project">read more</a>      </div>      <?php endforeach ?>    </div>

as can see, child div in question needs wrapped 'col-lg-4 col-md-6 col-sm-12' meaning on large devices row parent should printed every 3 divs, on medium every 2 , on small , small every 1.

are there ideas or examples on this? such hard thing google , i'm out of ideas. thanks!

you don't need "print" row every x cols. put of cols in single .row.

<div class="row">     <div class="col-lg-4 col-md-6 col-sm-12 project_box">..</div>     <div class="col-lg-4 col-md-6 col-sm-12 project_box">..</div>     <div class="col-lg-4 col-md-6 col-sm-12 project_box">..</div>     <div class="col-lg-4 col-md-6 col-sm-12 project_box">..</div>     <div class="col-lg-4 col-md-6 col-sm-12 project_box">..</div>     ... </div>

this known column wrapping.

however, if content of each col varies in height, need use "clearfix" responsive resets every x cols, or make columns same height. otherwise you'll have the height problem.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
