The colored box before the example color lightgoldenrodyellow is almost invisible. Maybe give it a small border or choose another color as example.

3rd paragraph from from the end (3rd item in 2nd list on the page)

In "The function calc() from CSS Values & Units Level 3 not only is very powerful for performing calculations, but also very well supported, even today." the words "CSS Values & Units Level 3" should probably be in bold type.

Because of the line break in the code block there should be a backslash after “height="100"”, too.

Code Block

linear-gradient(90deg, #655 41px, transparent 0); should be: linear-gradient(90deg, #655 23px, transparent 0); and background-size: 41px 100%, 61px 100%, 83px 100%; should be: background-size: 83px 100%, 61px 100%, 41px 100%; In the online dabblet example the code is correct.

bottom comment

"Relatively prime numbers have no common divisors" => Relatively prime numbers have no common divisors except 1 "a prime number is relatively prime with any other number" => PRIME NUMBER and RELATIVELY PRIME are two different concepts. It has no necessary connection about them.

last link in last text paragraph

Dudley Storey’s website has now the adress thenewcode.com instead of demosthenes.info. The old link is routed to the new one, so this is a minor problem. To make typing the adress easier it’s also possible to omit the article title in the link and end at after the article number: thenewcode.com/840

The 2nd code block

`0` should be `0 0`. Because `0` of background-position means `0 50%`. (Originally submitted by @GalliLiu)

1st paragraph in "Quarter ellipses"

In "Following a similar thought process as before, we can notice that to create a quarter ellipse, one of the corners needs to have a 100% radius both horizontally and vertically, and the other four will have no rounding." "four" should be replaced with "three" (one corner with 100% and the other three with 0, together four).

I suppose that "1/8th" should be "1/8" or "eighth".

Last code block / figure 3.29

The color declarations are different in the code (#58a and #655) for easier debugging. However, in figure 3.29 only #58a is shown as a gradient color.

First code block

In the two `linear-gradient` code line, `#58a` and `#655` need to be exchanged for each other to match Figure 3.28. (Submitted by @ArvinTung)

The colored box before the color example #58a shows the wrong color (#655?). It should be blue instead.

First paragraph

"Yes, a negative `animation-delay` is not only allowed by the specification, but is very useful for cases like this:" cannot link up the following quotation of spec. The last part of this sentence ("... but is very useful for cases like this") should be removed, because those use cases have been moved to the side note of "Tip!".

codeblocks for figure 4.6 and 4.7

The figures don’t show the box-shadows specified in the code examples. With “box-shadow: 2px 2px 10px rgba(0,0,0,.5);” there a shadow on the top and the left side should be visible. If the code shall fit the figures it should say “box-shadow: .1em .1em .1em rgba(0,0,0,.5);” as the online example. (Four places to correct: caption to figure 4.6 and all code blocks on page 136).

Last paragraph

This sentence: "The first filter we will apply is sepia(), which gives the image a desaturated orange-yellow tint, with most pixels having a hue of around 35–40." should probably refer figure 4.10

The filter sepia() seems to need a value to work, it should be sepia(1). That’s also true for the online example at play.csssecrets.io/color-tint-filter

last paragraph

In the code examples the background color is hsla(0,0%,100%,.3), thus white with 30% opacity. In the text it says “being 25% opaque”.

First paragraph of "The solution" section

In "Their main premise is usually adding two triangles on the top-left corner: ..." it should probably be "top-right corner"; in the previous paragraph is was stated that "usually the top-right or bottom-right one" get this style.

Last paragraph before Play!

In "As you can see in Figure 4.28, this finally gives us a nice, flexible, minimalistic rounded corner." instead of "rounded corner" it should be "folded corner".

Side note

If there was something like ":nth-line()", it should be a "pseudo element", just like "::first-line".

In this sentence "...as each stripe accounts for two lines", instead of "each stripe", "each tile" might be more proper, because readers may consider one tile as two stripes.

The only code snippet

In the code snippet we use "tab-size: 4;", but on the figure the code is "displayed with a tab width of two characters". From the text in the following paragraph - "As you can verify in Figure 5.13, it now looks much easier to read." - it becomes clear, that the figure should reflect the value used in the code snippet. Therefore, in the code snippet it should be changed to "tab-size: 2;".

IMHO the text contained the table would better reflect the change to table-layout: fixed. Now there is a contradiction between content and its former self-explaining charcter on page 267.

The footer shown there does not stick to the bottom. It should, since the content is long enough.

Tip at the lower right corner of the page

Currently the tip says: "when using flex: 2 for main and flex: 1 for footer, the height of the footer would be twice the height of the content”. Shouldn’t it be the opposite: "the main will receive 2 pixels for every pixel that is received by footer”? Or do I misunderstand the sentence?

"...We want the timing function of the main direction to be the accelerating one (ease-out) and the one of the reverse direction to be decelerating (ease-in)..." In this sentence, `ease-out` and `ease-in` should be exchanged for each other. (Submitted by @406298102 )

If an animated GIF is set "global palette", then all frames share the 256 color palette; but, if it's set "local palette", then each frame has its own 256 color palette. However, local palettes usually cause bigger file size.
