<h1>Western Electric Big Button Phone</h1>
<p>The Western Electric Big Button phone was introduced around 1974. It was made available in two color schemes, one orange/yellow and another blue/green. This pen imitates its style using a modern font (Work Sans) and some trickery with text shadows and strokes.</p>

// A recreation of the Western Electric Big Button phone produced in the 1970's.  Recreated using flexbox, grid, text shadows, and text strokes. This pen encountered several CSS quirks.

// First, is that setting a border radius and overflow:hidden breaks anti-aliasing on the border radius, leaving a jagged appearance. This was worked around a bit by adding a very soft light box-shadow on the side that has the border radius. This alleviates the problem somewhat.

// Second, text-stroke is still crudely implemented in browsers.  All text strokes are drawn on the outside of the glyph which changes the shape of the glyph. Additionally, text shadows are sized using the inside of the glyph, and end up smaller. To work around this, I oversized the text-stroke and then tried to position each glyph so that the stroke slightly overflowed the container and was cut off. This gives a smoother appearance, but is imprecise and cuts a few of the characters off.
