Part 1: Typography

The first "normal" paragraph should have 23px under the lead paragraph

  1. Font-size 18px
  2. Line-height 28px
  3. Margin-bottom 24px
.lead{
  font-family: "If Sans Bold", Arial, sans-serif;
  font-weight: normal;
  font-variation-settings: 'wght' 126;
  font-size: 18px;
  line-height: 28px;
  letter-spacing: normal;
  margin-bottom: 24px;
}

LGTM!

Or?

~ 20%

Developers and designers often speak different languages

// Two figures with speech bubbles

1: Parlez vouz REM?
2: Que?

CSS gives us the illusion that it understands design

.heading{
  font-size: 18px;
  line-height: 28px;
}

It looks pretty easy?

CSS

Design

To the left, what CSS does. To the right is what the designer is expecting to see. CSS centers the text in the line-height. The designer align it to the baseline, the bottom of the line-height.

Developers are left tweaking the CSS until it looks good

Some versions of typography metrics calculators to find the metric (the dimensions and properties)

From left to right: 1. nothing is done 2. with basekick 3. Normalized, with adjusted line-heights based on baseline grid (4px/8px)

Part 2: Colors

Sketch

The colors are not specified

🤔

Manual fetching of colors

#C62334

#F52340

#B82A38

#C82334

Get the point?

Decent communication

Too many colors and too few guidelines

Too few colors and too strict guidelines

Communicated by different nomenclature

Part 3: Icons

Viewbox and non-centered icons

pin 3

Stroke and boundaries

Using fill AND stroke..

Missing icons in the set

// Puzzle

1: I see that I'm missing some pieces, but the box is empty..

Different icon styles in the set

// Puzzle

Dad: Why do we have piecec from 4 different puzzles in the box?
Child: I think they fit nice together!

Part 4: Responsive

Static sketch

🤔

Sketches for mobile

😟

The developer is left to "fill in the gaps" in different breakpoints

But what about larger screens?

Denne talken vil vise smertene en utvikler har med designskissene når utvikleren implementerer typografidesign. Har du noen gang lurt på hvorfor avstanden mellom tittelen og teksten sier 30px i skissen, men at det ikke stemmer overens med html og css? Vel, jeg vil få deg til å forstå hvorfor og hvordan du løser dette.
