Your CSS style is written incorrectly. When adding the class name, it was added to the same element, and there is an extra space in the middle of your style. container. lakisa menu+nav li. The correct example should be

/*  big blue SPINNER */
.container.lakisa-menu .circle {
transform: rotate(-70deg);
}

.container.lakisa-menu+nav li {
transform: translateX(0);
transition-delay: 0.3s;
}

Is this the effect you want to achieve by clicking and rotating?
