Shopify changing the layout of the collections - html

Question

I would like to change the layout of a page of collections, right now it's just one column. I would like to make it at least 3 per row.
Here is the existing layout
to something like this
1:
Here's the code
<div id="content" class="col-md-12 center-column content-with-background">
<div class="row">
<div class="col-sm-12">
{{page.content}}
</div>
</div>
</div>
{% comment %}
Collections are listed here.
{% endcomment %}
{% capture uses_minimal_framework %}{% include 'product-loop' %}{% endcapture %}
{% if uses_minimal_framework contains 'Liquid error' %}
{% assign uses_minimal_framework = false %}
{% assign grid_item_width = 'large--one-quarter medium--one-third small--one-half large--col-3 medium--col-4 small--col-6' %}
{% else %}
{% assign uses_minimal_framework = true %}
{% assign grid_item_width = 'span3' %}
{% endif %}
{% assign image_size = 'medium' %}
{% if linklists[page.handle].links.size > 0 %}
{% assign number_of_links = 0 %}
<div class="grid-uniform{% if uses_minimal_framework %} row{% endif %} clearfix">
{% for link in linklists[page.handle].links %}
{% if link.type == 'collection_link' %}
{% comment %}
If we have a collection link.
{% endcomment %}
{% assign collection = link.object %}
{% assign number_of_links = number_of_links | plus: 1 %}
<div class="grid__item grid-item product-grid-item {{ grid_item_width }} text-center">
<div class="grid__image product-grid-image">
<a href="{{ link.url }}" class="grid-image--centered">
{% comment %}
Bring in the featured image of the first product in the collection if no collection
image has been uploaded for it.
{% endcomment %}
{% if collection.image %}
<img src="{{ collection | img_url: image_size }}" alt="{{ link.title | escape }}">
{% else %}
{% assign product = collection.products.first %}
<img src="{{ product | img_url: image_size }}" alt="{{ link.title | escape }}">
{% endif %}
</a>
</div>
<p class="collection-grid__item-title">
{{ link.title }}
</p>
</div>
{% if uses_minimal_framework %}
{% cycle 'clear-item': '', '', '', '<div style="clear:both"></div>' %}
{% endif %}
{% elsif link.type == 'page_link' %}
I don't know where to edit the code so i copied the part i think it is in. Thank you so much.

Try changing the 3rd line
<div class="col-sm-12">
to this
<div class="col-md-12">
That should resize it to fit more items on the screen.
