Have you worked with Quasar before? Have you tried to customize and style it?

Yes, I have worked with Quasar Framework, which is based on Vue.js and provides many ready-made UI components.

For customization and styling, I used the following approaches:

• Overriding theme variables (CSS variables) to change colors, padding, and fonts.
• Using SCSS/LESS for more flexible component styling.
• Creating custom components based on Quasar with extended functionality.
• Using slots to insert custom content into standard components.

An example of overriding the button color via a CSS variable:

:root {
  --q-btn-bg-color: #4caf50; /* green background for buttons */
}

Thus, you can quickly adapt the appearance to the project design.
