| 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> | |
| function startTest() | |
| { | |
| var targetRange = document.createRange(); | |
| /* We first create an empty range */ | |
| targetRange.selectNodeContents(document.getElementById("test")); | |
| /* Then we set the range boundaries to the children of div#test */ | |
| window.getSelection().addRange(targetRange); | |
| /* Finally, we now select such range of content */ | |

| <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. | |
