I'm looking for a solution to this problem:

I have a lwc that get passed a text and displays it, but when it's too long (being a title I can't truncate it) I'd need to resize it, to make sure the entire text is displayed and fits his container.

How can I do this?



import { LightningElement, api } from 'lwc';
export default class LwcAppStoreTile extends LightningElement {
@api appname;


    <div class="class1">{appname}</div>

.class1 {
    height: 30px;
    width: 182px;
  • Can you show some image with some code what are you trying to achieve? – Nagendra Singh Jan 13 at 12:27
  • I added the code, not that makes much difference – Francesco Ghiselli Jan 13 at 12:40
  • It has fixed width and height. Should it resize horizontally or vertically? – RubenDG Jan 13 at 17:59
  • I need to resize the text, not the container – Francesco Ghiselli Jan 14 at 15:42

I know 2 ways to adjust font-size function to the size of the screen :

  1. The most simple is to use the vw unit which represent 1/100e of viewport size (more info):


h1 { font-size: 8vw }
h2 { font-size: calc(1em + 5vw) }
  1. Use media query in your css : https://www.w3schools.com/css/css_rwd_mediaqueries.asp
  • I don't need the text to resize based on the screen. The text need the fit inside a div with certain dimensions. – Francesco Ghiselli Jan 14 at 14:57
  • I dont find anything else in case of LWC. I think the best parctice here is to use vw unit. Other way you have external libraries but I personally prefert avoid them as much as possible => css-tricks.com/fitting-text-to-a-container/… – Badbaxx Jan 15 at 8:42
