<!-- | |
The initial version of this test was relying on color | |
composition and was predicting a lime-green-ish (#7FBF80: | |
slightly desaturated lime green) background color for "Txet". | |
"#7fbf80 color description : Slightly desaturated lime green" | |
https://www.colorhexa.com/7fbf80 | |
This test does not rely on color composition but the | |
test nevertheless verifies the ::selection overlay drawn | |
over the ::grammar-error overlay. | |
Chromium 83+'s selection highlight will vertically | |
extend to line box top and bottom... which is | |
under an eventual discussion in | |
https://github.com/w3c/csswg-drafts/issues/5395 | |
One easy way to work around this issue | |
would be to set 'line-height' to '1' instead of | |
'90px'. | |
--> | |
<style> | |
div | |
{ | |
font-size: 60px; | |
line-height: 1; | |
/* | |
We deliberately set line-height to 1 in order | |
to avoid/work around a possible difference | |
of rendering of highlight overlay among browsers. | |
In Chrome 80+, the selection highlight | |
overlay will extent vertically to include line | |
box top and line box bottom. This is not | |
the case in Firefox 68+. | |
*/ | |
} | |
div::selection | |
{ | |
background-color: rgba(0%, 50%, 100%, 0.5); | |
/* | |
a very lite blue color | |
according to | |
https://www.colorhexa.com/7fbfff | |
*/ | |
color: yellow; | |
} | |
div::spelling-error | |
{ | |
background-color: yellow; | |
color: red; | |
} | |
</style> | |
<script src="support/selections.js"></script> | |
<p>PREREQUISITE: User agent needs to have an enabled and capable spelling error module. If it does not, then this test does not apply to such user agent. | |
<p>Test passes | |
<ul> | |
<li>if each glyph of "Txet sample" is yellow | |
<li>if "Txet" has a desaturated lime green background | |
<li>if " sample" has a very lite blue background and | |
<li>if there is no red. | |
</ul> | |
<!-- | |
The bad spelling of Txet is intentional and part of this test. | |
https://html.spec.whatwg.org/multipage/interaction.html#spelling-and-grammar-checking | |
• contenteditable makes the text “checkable for the purposes of [spelling and grammar checking]” | |
• spellcheck tries to enable spelling and grammar checking (subject to user preferences) | |
• lang tries to guide the UA towards checking the text in English (but the UA may ignore this) | |
--> | |
<div id="test" contenteditable="true" spellcheck="true" lang="en">Txet sample</div> | |
<script> | |
const test = document.querySelector("#test"); | |
selectNodeContents(test); | |
trySpellcheck(test); | |
