What is the meaning of flex 1 in terms of CSS?

In the context of web development, flex 1 in the realm of CSS flexbox is a flex item’s property that is used in the distribution of available spaces along the container of flex main axis.

Here is the explanation given with an example:-

Consider a scenario where you have a flex container that contains flex items:-

HTML

  Item 1

  Item 2

  Item 3

CSS using flex 1

.flex-container {
  Display: flex;
}
.flex-item {
  Flex: 1;
}

When you implement the flex 1 to the flex items, it will assign a flexible size to all the items of the flex container. This property would distribute the available spaces equally along with the main axis of the flex container.

Therefore, flex 1 allows you to dynamically grow or manipulate the items of the flex container according to your needs and requirements which helps you further in the creation of web layout effectively.
