Как создать и использовать CSS спрайт?

CSS-спрайт – это метод объединения нескольких изображений в один файл для оптимизации загрузки и отображения на веб-странице.

Зачем нужны спрайты?
Уменьшают количество HTTP-запросов → вместо 10 изображений браузер загружает 1 файл
Ускоряют загрузку сайта → меньше сетевой нагрузки
Кэшируются в браузере → реже загружаются заново

Создание CSS-спрайта
Допустим, у нас есть 3 иконки:
icon-home.png
icon-user.png
icon-settings.png
Мы объединяем их в один файл (sprite.png):

Использование спрайта с CSS
Теперь нам нужно показать нужную часть изображения с помощью background-position.

.sprite {
  background: url("sprite.png") no-repeat;
  display: inline-block;
  width: 32px;
  height: 32px;
}

/* Позиции каждой иконки */
.icon-home { background-position: 0 0; }  /* Первая иконка */
.icon-user { background-position: -32px 0; }  /* Вторая иконка */
.icon-settings { background-position: -64px 0; }  /* Третья иконка */

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each.
