+.container,

[saroyanm, 2016/11/08 16:19:40]

What suppose to be the difference between the container and .row ?

[juliandoucette, 2016/11/09 14:51:16]

Acknowledged.

[juliandoucette, 2016/11/09 14:51:16]

We decided to move .container to _content.scss.

[juliandoucette, 2016/11/09 19:47:18]

Done.

+.container-fluid
+{
+  margin: 0px auto;
+  padding: 0px $small-space;
+  max-width: 100%;
+}
+
+.container:after,

[saroyanm, 2016/11/08 16:19:40]

Note: we might use double colon as soon we will drop IE8 support.

[juliandoucette, 2016/11/09 14:51:16]

Acknowledged.

[juliandoucette, 2016/11/09 19:47:18]

Done.

+.container-fluid:after,
+.row:after
+{
+  content: "";
+  display: table;

[saroyanm, 2016/11/08 16:19:40]

I'll suggest to use display: block;
I can't see reason of using display: table; if you are not planing to use table
like structure. While clearing with the block element sounds more reasonable IMO
and provide less questions even if it's used with the display:table in other
examples.

[juliandoucette, 2016/11/09 14:51:16]

Acknowledged.

I will change this to display:block.

[juliandoucette, 2016/11/09 19:47:18]

Done.

+  clear: both;
+}
+
+.row
+{
+  margin: 0px -$small-space;

[saroyanm, 2016/11/08 16:19:39]

Why do we need to use negative margins here ?

[juliandoucette, 2016/11/09 14:51:16]

It should be (-$small-space) to avoid incorrect calculation.

[juliandoucette, 2016/11/09 14:51:16]

Negative margin reasoning:

To add consistent padding around all columns except for the first left padding
and last right padding.

[juliandoucette, 2016/11/09 19:47:18]

Done.

+}
+
+.column
+{
+  position: relative;
+  min-height: 1px;
+  padding: 0px $small-space;
+  width: 100%;
+}
+
+[dir="ltr"] .column

[saroyanm, 2016/11/08 16:19:39]

detail: .column selector should be enough, same applies to similar "ltr" styles
below.

[juliandoucette, 2016/11/09 14:51:16]

Acknowledged.

This only applies to properties which are overridden by rtl. 

[juliandoucette, 2016/11/09 19:47:18]

Done.

+{
+  float: left;

[saroyanm, 2016/11/08 16:19:40]

I'm not opposed of using floats, because seems like having the solution of
clearing it should cover most of the issues that appears when people forget to
clear, but I'd like to ask @Thomas opinion regarding this as well.

[juliandoucette, 2016/11/09 14:51:16]

Julian - Acknowledged.

@Thomas's opinion is still requested.

+}
+
+[dir="rtl"] .column
+{
+  float: right;
+}
+
+@media (min-width: $mobile-breakpoint)
+{
+  .container
+  {
+    width: 540px;

[saroyanm, 2016/11/08 16:19:39]

Why is the width specification for the container is necessary here and below ?
Maybe I do not know the difference between container and row, that why it's
questionable for me.

[juliandoucette, 2016/11/09 14:51:16]

Acknowledged.

- We are moving container outside
- We set the width of the regular container to avoid scaling edge cases

[juliandoucette, 2016/11/09 19:47:18]

Done.

+
+@media(min-width: $desktop-breakpoint)

[saroyanm, 2016/11/08 16:19:39]

I can't see a reason why we need to specify desktop-breakpoint, I think this
should be the default style, BTW the mobile-breakpoint is missing.

[juliandoucette, 2016/11/09 14:51:16]

Acknowledged.

- Since we are styling mobile first, $mobile-breakpoint is not necessary 

[juliandoucette, 2016/11/09 19:47:18]

Done.

+  }
+
+  .one-fourth
+  {
+    width: 25%;
+  }
+
+  [dir="ltr"] .pull-one-fourth

[saroyanm, 2016/11/08 16:19:40]

A suggestion regarding pulling and pushing. 
I'm not really sure if we will use the part of the functionality from it, so
maybe we can make it simpler, what about current implementation ? It will make
things more simpler IMO:

.one-fourth
{
  width: 25%;
}

.one-fourth.move-to-end
{
  left: 75%;
}

.one-fourth.move-to-start
{
  left: 0px;
}

Let me know if you think that in our designs we are going to use pull and push
functionality in the way you have implemented.

[juliandoucette, 2016/11/09 14:51:16]

Acknowledged.

- naming TBD
- we'll cover 1/2, 1/3 + 2/3, 1/4 + 3/4 (not individual 1/4s and 1/3s)

[juliandoucette, 2016/11/09 19:47:18]

Done.
