Bootstrap 3 : 实现5栏设计 5 columns layout with Twitter Bootstrap

By default Bootstrap does not provide grid system that allows us to create five columns layout, but as you can see it’s quite simple.

At first you need to create default column definition in the way that Bootstrap do it. I called my classes col-..-15.

.col-xs-15,
.col-sm-15,
.col-md-15,
.col-lg-15 {
    position: relative;
    min-height: 1px;
    padding-right: 10px;
    padding-left: 10px;
}

Next you need to define width of new classes in case of different media queries.

.col-xs-15 {
    width: 20%;
    float: left;
}
@media (min-width: 768px) {
.col-sm-15 {
        width: 20%;
        float: left;
    }
}
@media (min-width: 992px) {
    .col-md-15 {
        width: 20%;
        float: left;
    }
}
@media (min-width: 1200px) {
    .col-lg-15 {
        width: 20%;
        float: left;
    }
}

Now you are ready to combine your classes with original Bootstrap classes. For example, if you would like to create div element which behave like five columns layout on medium screens and like four columns on smaller ones, you just need to use something like this:

<div class="row">
    <div class="col-md-15 col-sm-3">
    ...
    </div>
</div>
