GETTING MORE FLEXIBLE WITH FONT SIZE MEASUREMENTS

px is an absolute unit of measurement - px units don't scale

!em is not an absolute unit -

it is a unit that is relative to the currently chosen font size.

PIXELS VS. EMS

body  {  font-­‐size:62.5%;  }  h1  {  font-­‐size:  2.4em;  }  /*  =24px  */  p    {  font-­‐size:  1.4em;  }  /*  =14px  */  li  {  font-­‐size:  1.4em;  }  /*  =14px?  */  !li  li  {  }  !1.4em  =  14px   BUT  14  *  1.4  =  20

FONT SIZE COMPOUNDS

The em unit is relative to the font-size of the parent, which causes the compounding issue.

!The rem unit is relative to the root—or the html—

element.

REM == ROOT EM

BUILDING MOBILE FIRST

Building from Small Screen Towards Large Screen !

Which in turn saves you from having to overwrite lots of CSS in the long run

BUILDING MOBILE FIRST

@media  only  screen  and  (min-­‐width  :  30em)  {  …  }

STARTING LIGHT

@media  only  screen  and  (max-­‐width  :  30em)  {  …  }

WHAT ABOUT MAX-WITDH?

@media  only  screen    and  (min-­‐width  :  30em)  and  (max-­‐width  :  34.375em)  {  !

  /*  fine  tuning  for  certain  elements  */  !

}

MY EXCEPTIONS

ORGANIZING YOUR MEDIA QUERIES

Breakpoints don’t necessarily have to be device sizes !

Rather set them where stuff looks good !

Consider most commonly used devices (Which can be quite a guessing game)

You could se"le for fixed breakpoints… but that’s cheating! ✌️

!Why should definitely opt for a fluid grid

popular devices.

USING EM’S IN MQ’S

@media  only  screen  and  (min-­‐device-­‐width  :  37.5em)  {  …  }

100% ZOOM IN 1024PX WIDE VIEWPORT

175% ZOOM IN 1024PX WIDE VIEWPORT W/ EM BASED MQ (SAME VIEW AS IN A 320PX VIEWPORT)

100% ZOOM IN A 320PX WIDE VIEWPORT

<link  rel="stylesheet"  href="css/app.css"  />  <link  rel="stylesheet"  href="css/480.css"  />  <link  rel="stylesheet"  href="css/768.css"  />  <link  rel="stylesheet"  href="css/1024.css"  />  !

OR  @import  “480.css”;  @import  “768.css”;  @import  “1024.css";

THE EARLIER DAYS OF RWD

.panel-­‐wrap  {     margin-­‐bottom:  0.5rem;     @include  media(30em)  {       padding-­‐left:  0.3125rem;       padding-­‐right:  0.3125rem;     }     @include  media(38em)  {       padding-­‐left:  0.6375rem;       padding-­‐right:  0.6375rem;     }     @include  media(50em)  {       padding-­‐left:  0.9375rem;       padding-­‐right:  0.9375rem;     }  }

I PREFER ONE FILE WITH INLINE MQ’S

IMPORTING PARTIALS

SELECTORS & CHOICES

CLASSES VS. ID’S

1. ID’s & Classes all over the place

2. ID’s for main elements, classes mostly everything else

3. ID’s only for JavaScript, classes for everything CSS

MY SELECTOR EVOLUTION

SEMANTIC CLASSES !

VS. !

PRESENTATIONAL CLASSES

USE CLASS ATTRIBUTES WITH SEMANTICS IN MIND

Choose your class names to what the element is instead of how it looks

.blue-­‐box  {        background:  #51A7F9;      }

.blue-­‐box  {        background:  #DC0100;      }

.box  {        background:  #F28717;      }

ANOTHER ADVANTAGE OF USING SEMANTIC CLASSES OVER PRESENTATIONAL CLASSES

CHANGE ELEMENT APPEARANCE WITHOUT TOUCHING YOUR HTML

<div  class=“small-­‐12  medium-­‐8  large-­‐6”>      …  </div>

<div  class=“small-­‐12  medium-­‐8  large-­‐6”>      …  </div>

.small-­‐12  {  declaration  here  }  !

.large-­‐6  {  declaration  here  }

.news-­‐item-­‐block  {      @extend  .small-­‐12;      @extend  .large-­‐6;  }

<div  class=“news-­‐item-­‐block”>      …  </div>

.news-­‐item-­‐block  {      @extend  .to-­‐whatever-­‐you-­‐want;     and-­‐another-­‐property:  value;  }

<div  class=“news-­‐item-­‐block”>      …  </div>

CLASS NAMES

CLASS NAMING IS HARD

DON’T MAKE YOUR LIFE HARDER THAN IT NEEDS TO

BE

MY FAVORITE WORD:

SPECIFICITY

★ Try to avoid long selector chains

★ They are painful to overwrite

★ Nest 2 or max 3 levels deep

★ Check your output file when nesting rules

IF YOU NEED TO USE !IMPORTANT TO OVERWRITE A STYLE, YOU PROBABLY MESSED UP SOMEWHERE ELSE!

DON’T WORRY ABOUT THE SIZE OF YOUR CSS

!

RATHER CARE ABOUT IMAGE SIZE

IMAGES

AVERAGE RESPONSIVE SITE SIZE

INCREASE SINCE 2011

IMAGES OFTEN ACCOUNT FOR MOST OF THE DOWNLOADED

BYTES ON A PAGE. !

OPTIMIZING IMAGES CAN OFTEN YIELD LARGE BYTE

SAVINGS AND PERFORMANCE IMPROVEMENTS.

You have to make decisions and sacrifices sometimes. As long as you know why you made them, it should be

alright to do so
