Some basic documentation can be found here.

Css – How can I implement a "see more" button on a div with set height, but very large content?

I’m sure this has been asked many times before, but I’m having difficulty wording this in a way that gets me results. I have also found very outdated answers (8+ years ago), and they seemed too complicated considering the technology we have today.The modern solutions I’ve found work specifically with text, by using things like -webkit-line-clamp

This project uses Angular, Angular Material, and Sass, so I’m sure there is an elegant way to achieve this. I just need to implement something like the image below:

enter image description here

The content shown inside will be a bar chart, but I don’t think this makes much of a difference.

Again, I’m sorry for asking a, no doubt, extremely repeated question, but I just haven’t found any answers or tutorials. A suggestion for search terms would already help me a lot.

    You can get it only with a variable

    more:boolean=false;

<div [style.max-height.px]=more?50:null>
    ..your image..
</div>
<button (click)="more=!more">{{more?'show less':'show more'}}</button>

    well, you can create a component, or a directive with this idea, but it’s only change the style.max-height binding with a variable.
