Вы можете использовать javascript для достижения этого, установив стиль отображения левой боковой панели на none
при отсутствии содержимого. Если я прав в том, что вы хотите, вы хотите удалить боковую панель слева, если она пуста, и позволить основной и правой руке взять на себя сетку, да?
Вы можете проверить, пуст ли текст left-sidebar-content
, используя условное === ''
. Если он пуст, установите отображение вашего класса left sidebar
на none
. Когда в left-sidebar-container
есть контент, он будет отображать css, изначально определенный как display: grid
.
let left = document.getElementById('left-sidebar-container'); //<-- get the left-sidebar-container with its id
let leftSB = document.getElementById('left-sidebar'); //<-- get the left-sidebar with its id
let content = document.querySelectorAll('.content'); //<-- get the .content element using it class
let check = left.textContent; //<-- save the textContent inside a variable
if(check === ''){ //<-- conditional if statement to see if the textContent is set to '' or empty
leftSB.style.display = 'none'; //<-- set the display of the left-sidebar to none
}
.content {
display: grid;
grid-template-columns: minmax(0,.5fr) minmax(0,1fr) minmax(0,.5fr);
grid-column-gap: 2.5%;
grid-row-gap: var(--margin-bottom)
}
