What is Max-width?
Hello! Today we want to talk about the feature Max-width in CSS. This feature is one of the tools used for controlling and changing the width of an element on a web page. When talking about responsive design, Max-width can be your best friend! How? Well, stick around to understand.
Let’s assume you have an image that you want to resize across different devices. Using Max-width allows you to limit the width of an element (like an image) to a specific size. Thus, if the width of the image exceeds the predefined limit, it self-adjusts to the smallest possible size. However, if it is less than this amount, it remains unchanged.
Practical Usage
The main usage of Max-width is commonly in responsive design. For example, to prevent images from getting larger than the width of their containers in larger screens. This feature allows you to ensure that your design always fits properly on the screen.
An Example of Usage
Now let's take a real example of Max-width and implement it. In the example below, we want to make sure that an image never exceeds 100% of its container's width.
<style>
img {
max-width: 100%;
height: auto;
}
</style>
<img src="example.jpg" alt="example">
