I thought we were planing to move parts of normalize.css into reset.css and and
rename the file if needed. Or create separate normalize.css

[juliandoucette, 2016/11/10 17:42:07]

We split parts of normalize.css into _reset.scss and _content.scss. That's why
"this file contains parts of normalize.css". We have to give attribution to
comply with the MIT license.

Detail: please specify units where possible.

[juliandoucette, 2016/11/10 17:42:07]

Acknowledged.

[juliandoucette, 2016/11/11 16:27:10]

MDN prefers unit-less numbers for line-height values.

@see
https://developer.mozilla.org/en-US/docs/Web/CSS/line-height#Prefer_unitless_...

I recommend we leave this as-is.

[saroyanm, 2016/11/10 16:30:43]

The way the comments are written are affecting CSS file readability IMO.
I'll strongly recommend if there is a need for the comment to put it on top of
the group of selectors.
We can have this comments moved to HTMl file. We can have general comment on top
of both, ex.: "responsive container"

[juliandoucette, 2016/11/10 17:42:08]

Acknowledged.

[juliandoucette, 2016/11/11 16:27:11]

Done.

- I removed these comments (I don't think we need them).
- I removed .container-fluid (I don't think we need it).

- */
-.container-fluid
-{
-  width: 540px;

[saroyanm, 2016/11/10 16:30:45]

I thought the plan was to calculate the width from the breakpoint values.

[juliandoucette, 2016/11/10 17:42:07]

No. There is no algorithm to calculate these widths. They are based on browser
statistics.

[juliandoucette, 2016/11/11 16:27:14]

I have included ${device}-${width} variables in _variables.scss instead.

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

[saroyanm, 2016/11/10 16:30:44]

I do not think that this rules belong to current review, are they ? Looks like
grid specific implementation if I'm not wrong.

[juliandoucette, 2016/11/10 17:42:09]

I think you are wrong. These styles clear containers and any element that
contains the clearfix class. This applies to the grid and any other floating
elements (EG: float-start, float-end).

[juliandoucette, 2016/11/11 16:27:14]

Done.

I separated these classes and added more explanation.

-.container-fluid:after,
-/**
- * Force any element to clear all
- */
-.float:after

[juliandoucette, 2016/11/10 16:08:07]

This is a mistake. ".float" should be ".clearfix".

[juliandoucette, 2016/11/11 16:27:13]

Done.

-{
-  display: block;
-  clear: both;
-  content: "";
-}
-
-@media(min-width: $tablet-breakpoint)

[saroyanm, 2016/11/10 16:30:46]

Note: I do see a reason why @media queries are located after the .container
styles, but as soon we will add more rules into @media queries I think it would
be more convinient to move them on the bottom of the file. Weak suggestion: we
can move them to the bottom now.

[juliandoucette, 2016/11/10 17:42:08]

Don't you think that the rules that are applied to .container are more readable
if they are kept together?

[juliandoucette, 2016/11/11 16:27:14]

Done.

Looks like you and Thomas outnumber me on this one.

[saroyanm, 2016/11/10 16:30:46]

Maybe it's a personal opinion, but I kinda feel like the overwriting the rules
doesn't make the file more readable, what about removing headings from top
selectors and having only here, by changing the rule to:
margin: $medium-space 0px $small-space 0px;

What is the problem with border-box reset we have in Firefox ?

[juliandoucette, 2016/11/10 17:42:06]

Acknowledged.

[juliandoucette, 2016/11/11 16:27:11]

Done.

-  box-sizing: content-box;
-  /* Show the overflow in Edge and IE. */

[saroyanm, 2016/11/10 16:30:44]

Not really sure why we need overflow property on hr element ?

[juliandoucette, 2016/11/10 17:42:10]

It depends on how we style hr. The default style is overflow: visible except in
IE. Hence the normalize fix.

[juliandoucette, 2016/11/11 16:27:12]

Done.

Removed. These styles were not necessary for us.

-  height: 0px;

[saroyanm, 2016/11/10 16:30:45]

note: Feels like this style belongs to normalize.css

[juliandoucette, 2016/11/10 17:42:09]

I put the normalize.css things that apply to content in content.scss

[juliandoucette, 2016/11/11 16:27:12]

Most of the normalize.css changes are made irrelevant by our styles now. Let me
know if you find anything that smells.

[saroyanm, 2016/11/10 16:30:45]

Detail: seems like this also part of normalization and couple of styles below
I've also noticed. Make sense to decide where we want to move normalization
related properties, I thought we decided to move to reset.css

[juliandoucette, 2016/11/10 17:42:08]

See comment above.

[juliandoucette, 2016/11/11 16:27:12]

Correction:

These comments are no longer valid because I changed the CSS from normalize.css.
Font-family and font-size are set inconsistently across browsers. Setting them
for pre and code corrects this.

-  /* Correct the odd font sizing in all browsers. */

[saroyanm, 2016/11/10 16:30:44]

Why youtube ? I think this style shouldn't have specific website name. Previous
.embed were fitting better IMO.

I thought it was simpler for content developers.
