Understanding Overflow in CSS
In CSS, the overflow property is used to control how content that exceeds a restricted area is displayed. The different states of overflow include visible, hidden, scroll, and auto. overflow-x and overflow-y are used respectively to control horizontal and vertical overflow.
Relationship Between overflow-x and overflow-y
When overflow-y: auto is set, the browser tries to manage additional content vertically. However, in some cases, this setting may cause the content not to be displayed horizontally. This is because browsers prefer to confine content to one direction, especially when the overflow contains more content than the vertical space allows.
How overflow-y: auto Works
When overflow-y is set to auto, the browser only enables vertical scrolling when the content exceeds the limit. Conversely, if there is no additional content, it will not show any scrollbar. However, this property can inadvertently affect overflow-x, particularly when the internal content is significantly larger than the available vertical content.
Ways to Control overflow Better
If you want to avoid horizontal overflow being hidden, you can apply overflow-x settings separately. For instance, you could explicitly set overflow-x: visible; to ensure that the content is displayed horizontally.
<style>
.content {
width: 200px;
height: 150px;
border: 1px solid black;
overflow-x: visible;
overflow-y: auto;
}
</style>
<div class="content">
<p>This is a sample text with more content than allowed in a defined box.</p>
<p>If the width of this box is insufficient, this text should cause the scrollbars to appear.</p>

<style> Definition of CSS styles
.content Selector class for the element we want to apply the overflow property
width: 200px; Restricts the element's width to 200 pixels
height: 150px; Restricts the element's height to 150 pixels
border: 1px solid black; Adds a solid black border to the element
overflow-x: visible; Allows additional content to be displayed horizontally
overflow-y: auto; Enables vertical scrollbar only if there's additional content
