text-ellipsis

ellipsis	Show single line of text, cut overflow with ellipsis
ellipsis2	Show only two lines of text, cut overflow with ellipsis (line-height + max-height). Cons: It's no allowed to use `padding-bottom` on elements with `ellipsis2`. Text on it won't be hidden.

toggle

Work in progress.
This is an attempt to structure html/css for elements like checkboxes and radio buttons.

Define .toggle classes with .if-on and .if-off

The most basic toggle

.toggle.active .if-off { display: none; }
.toggle:not(.active) .if-on { display: none; }

<button v-on:click="toggle" v-bind:class="{active: is_active}" class="toggle">
    <span class="if-on">ON</span>
    <span class="if-off">OFF</span>
</button>

Use Case #1

There is a BUTTON with SVG icon and text inside. This two elements should have slightly different gray colors by default, but they should have the same red color when button is hovered by mouse.

One solution for this task is to use two separate elements with when generic .if-on and .if-off classes

<button class="toggle-hover app-color-silver1 app-hover-color-red">
    <svg-icon-close class="if-on app-color-silver2"></svg>
    <svg-icon-close class="if-off app-color-red"></svg>
    Disconnect
</button>

Another solution would be to use just one element but with a class prefixed with if-on

<button class="toggle-hover app-color-silver1 app-hover-color-red">
    <svg-icon-close class="if-on-app-color-red app-color-silver2"></svg>
    Disconnect
</button>

<style>
.toggle-hover .if-on-app-color-red { color: red; }
</style>
