Description Javier Fernandez 2019-03-05 16:09:12 PST
The CSS WG has resolved [1] add a deprecated note to prevent the usage of 'overflow-wrap: break-word' in favor of 'overflow-wrap: anywhere'.

The new value is described as follows:

I have sent the "intent to implement" request for Blink. Showing some public support in this bug would help to get the request approved.

Implementing this is a good idea. (You can consider this "public support.")

We already implement (the deprecated) word-break:break-word, which is defined[1] to "have the same effect as word-break: normal and overflow-wrap: anywhere." Therefore, implementing this should be fairly straightforward.

From looking at WebKit source code (RenderStyle::breakWords()), it appears that word-break:break-word is currently treated identically to overflow-wrap:break-word, which I think is incorrect according to the spec text quoted above. It would be cool if this project fixed this, too (though, of course, fixing this could be tracked in a separate bug).

@Myles, The wrapping behavior of word-break:break-word / overflow-wrap: anywhere is the same as that of overflow-wrap:break-word, but the effect on intrinsic sizing is different. A quick bit of testing shows that safari has the expected sizing behavior difference between word-break:break-word and overflow-wrap:break-word.

To test, you can try this:

  <section style=width:0>
    <div style=float:left>longword</div>

If you put overflow-wrap:break-word on the div, the longword will not wrap, but if you put word-break:break-word instead, it will.

It would be really nice to see this implemented so it can be used across the board - other major browsers support this since 2019 (Firefox) / 2020 (Chrome, Edge).

This bug seems to be fixed.

I think this is implemented and we pass 'WPT' tests as well: https://wpt.fyi/results/css/css-text/overflow-wrap?label=master&label=experimental&aligned=&q=overflow-wrap-anywhere

Do we need anything more here?
