webkit-line-clamp | JS polyfill CSS property -webkit-line-clamp | User Interface library

You've got an error in your CSS selector for your

You're selecting .list ul when your intention is ul.list

You can just display: inline-block; instead of display: table-cell; in .postInfo.

For displaying the full text from a multiple line snippet of the full text, you can add and remove classes to control the size and the ellipsis status.

I’m not sure there’s a way to put your More / Less button on the same line as the ellipsis, as -webkit-line-clamp ends the text at the end of the line, but you could put the button below the text.

Note: I’m using a button, rather than a link, as a button is better for accessibility (a link goes somewhere, a button does something).

-webkit-line-clamp doesn’t work in IE, so you won’t get the ellipsis, but the text block will still expand.

This solution does require setting the max-height of the text box in the CSS in a couple of places (I’ve used 3.375rem for three lines).

it's because the product_stock variable is undefined when you call it on the script. instead of using javascript code, just add the style directly to the PHP code.

You can do that in php

By looking at the component, you're doing two things upon clicking the button:

• removing the truncate class from the paragraph
• setting truncated property to false.

I would bind the class to the property, using :class="{ truncate: truncated }" and then the only thing in need of testing onclick is that truncated has been set to false (you don't want to test if Vue works).
This removes the need for your showAll to manually remove the class from the paragraph: Vue is data driven => you change the data, Vue manages DOM accordingly.

To make it as clear as possible: you should only test the component's logic and nothing else. You're not testing Vue, JavaScript or the browser. You trust that those work (other people are in charge of writing tests for them). So, in order:

• expect truncated to have the proper value upon mounting (effectively testing isOverflown() provides the expected output in each of the cases you care about)
• when truncated is true trigger a click on the button (no need to expect the button to exist when truncated is true, as you'd be testing if v-if works). After clicking the button, in $nextTick() expect truncated to be set to false.

And here is the list of things you should not test:

• that JavaScript works
• that Vue works (applies :class and :style, applies v-if, etc...)
• that the browser understands and applies -webkit-line-clamp
• that your testing library works
• that showAll has run after clicking the button (you want to be able to rename the method and your test should still pass if clicking the button sets truncated to false).

That's about it.

You will want to apply another class to the same div upon the user clicking 'read more'

This class should apply the none value to the line-clamp property that stops the text-overflow and ellipses from occurring.

Your css will be something like:

You can add Javascript Like this

Just do npm i react-lines-ellipsis --save and use like this
