![]() The overflow-x property controls horizontal overflow – in other words, overflow from the left and right of an element’s box. Instead of using the overflow, you can use the overflow-x and overflow-y properties to control the overflow horizontally and vertically. See the Pen css overflow: auto by HubSpot ( on CodePen. In the example below, both divs are defined have an overflow value of auto, but only the second div has scrollable overflow and a scrollbar. The “auto” value is similar to scroll, but adds a scrollbar only if the box has overflow. See the Pen css overflow: scroll by HubSpot ( on CodePen. However, a scrollbar is be added so users can scroll to see the content that’s not currently visible. To hide overflow from rendering outside the element’s box while enabling users to view that content, set the overflow property to “scroll.” The overflow will still be clipped at the box’s padding edge. A user could use the mechanisms defined by the CSSOM View Module, for example, to see the hidden content. Note that this value still allows programmatic scrolling, which means the box is technically a scroll container. See the Pen css overflow: hidden by HubSpot ( on CodePen. Also, it will not allow the user to view the content beyond the padding edge by scrolling. This will clip the content at the box’s padding edge. To prevent overflow from rendering outside the element’s box, you can set the overflow property to hidden. See the Pen css overflow: visible by HubSpot ( on CodePen. This is the default value of the overflow property. Instead, it will render outside the element’s box and may overlap with other elements on the page. Visible means that the overflowing content will not be clipped. The CSS overflow property has several ways to control overflow. ![]() When the content of an HTML element extends beyond any of the box’s edges - whether that’s the content edge, padding edge, border edge, or margin edge - it is called overflow. This box comprises four layers: the content itself, the padding, the border, and the margin. You can use the CSS overflow property to control what happens to the overflow.īefore we look at the overflow property, let’s clarify what we meant by the “element box.” According to the CSS box model, a box is generated for HTML elements. This can happen when an element has a specified height that’s too small for the content it contains. In CSS, overflow occurs when an element’s content does not fit entirely inside the element box. Whether you’re using plain CSS or a framework like Bootstrap, here’s what you need to know. Then, we’ll explain how to control it with the following CSS properties: ![]() This way the article area receives its own scroll, and the header always stays on top.In this post, we’ll explain what overflow is in CSS. Remove the background color from the blue container, and add overflow: scroll to it.Paste the result of the Text task in the Box model article into the centered container.In the blue container, create a single child container that takes full width using width: 100%, but doesn’t expand beyond the specified width using max-width: 480px.Since you need to center the article, you need to turn the blue container into a flex parent container using display: flex and center the content horizontally using justify-content: center.See the Pen Flex-overflow-Task 1.1, step 1 by And on CodePen. You should be able to see in the Preview that this container takes all the available space: Create another child container with a blue background.You can also use the code from prototype from the article. Paste the result of the task in the flex: 1 article as the first child of the flex container.In HTML, create a flex parent container.See the Pen Flex-overflow-Task 1.1 by And on CodePen. # ArticleĬreate a low-fidelity design of an article page: overflow specifies the behavior of child containers when they don’t fit into the container.īy default, when a child container is larger than its parent, it remains visible.Wwith backgrounds applied, you can see how the child goes beyond the parent’s boundaries:ĭon’t forget to collapse the containers that you don’t work with to make navigating the code easier. The overflow property isn’t directly related to flexbox, but it is required for most layouts created with flex. Nesting flex containers within flex containers-each with its own set of properties-allows you to create almost any layout you can imagine. The content area is also a flex parent populated with cards, that are flex containers themselves, and so on.įlexbox allows you to organize items in one direction and to control their alignment. The bottom toolbar is a flex parent to five tabs.
