Мне нужна ваша помощь
Я новичок в веб-разработке
Можете ли вы объяснить, почему поле ввода не выравнивается по центру?
<"input type="text" id="search_bar" class="form-control" placeholder="Search" align="center">
В CSS я пытался добавить "float:center;" в нескольких местах в CSS, связанных с полем ввода, но, похоже, ничего не работает вообще.
вот код:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
