Изменение класса css с использованием переменной php
вам нужна ваша помощь. Так как название предлагает, я пытаюсь изменить классы css с помощью переменной PHP. Поэтому в основном я хочу создать цикл, который эхо кода. Но я хочу, чтобы класс div в первом цикле был другим – он должен быть скрыт.
Вот упрощенный код, который я сделал, чтобы сделать проблему понятной. Я не знаю, где ошибки. Пожалуйста, порекомендуйте.
html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> .hidden < visibility:hidden; >.visible < visibility:visible; >.firstclass php $case = 4; $page = ""; $class = ""; if ($page == 0) < $class = "hidden"; >else < $class = "visible"; >for ($page = 0; $page < $case; $page++) < echo "This is page $page
"; > ?> Вам нужно поставить условие if в цикл
Поскольку существует условие, когда $ page == 0, то он даст скрытый класс, поэтому, если вы просто поместите его за пределы цикла, тогда $ page никогда не получит значение int, потому что в верхней части условия есть $ page знак равно
for ( $page = 0; $page < $case; $page++ ) < $class = ($page == 0) ? 'hidden' : 'visible' ; echo 'This is page' .$page. '
'; > for ($page = 0; $page < $case; $page++) < echo ("This is page $page
"); > div class and style together in PHP
In your style, use the same name:value; syntax that you use in your CSS (notice the colon (:) between the two:
. 1
2
3
4
5
6

Good luck in the future

the syntax is like width: 100px !important and not width=100px !important

HTML div style class
Inserting style for div, there are three ways:
External style sheet, — In this case we make file as style.css where we add CSS style
Internal style sheet, — We add CSS style betweenthem:
Inline style,
For any on your page, you can specify any CSS property as: color, font-style, font-family, font-size, background, etc.
Example: On this window you can edit online this script,
div class and internal style.
.text font-family: Verdana, Geneva, sans-serif;
font-size: 16px;
color: #09C;
background-color: #CCC;
margin: 12px;
padding: 15px;
