How to Craft CSS Media Queries for Multiple Screen Sizes

To ensure your website renders seamlessly across various devices, understanding CSS media queries is crucial. This article guides you in creating efficient media queries to optimize your layout for specific screen sizes.

Understanding Your Screen Sizes

You need to determine the screen sizes you want to support. In the provided scenario, you're targeting:

• 640x480
• 800x600
• 1024x768
• 1280x1024 (and larger)

Creating Media Queries

To create effective media queries, follow these guidelines:

@media media_condition {
  /* CSS styles for the specified condition */
}

In this condition, the media_condition defines the parameters for when the CSS styles should be applied. Let's break down the media queries:

@media screen and (max-width: 640px) {}

This query selects all screens with a maximum width of 640px. It ensures that the styles are applied for screens up to 640x480.

@media screen and (max-width: 800px) {}

Similar to the previous query, this one targets screens up to 800x600, excluding 640x480 screens.

@media screen and (max-width: 1024px) {}

This query selects screens up to 1024x768, excluding 800x600 screens.

@media screen and (max-width: 1280px) {}

This query targets screens up to 1280x1024, excluding 1024x768 screens.

By using a series of increasing max-width media queries, you ensure that the correct styles are applied to the appropriate screen sizes.

Comprehensive Media Query Solution

Combining all the queries into a single document, you can use the following code to cover all the target screen sizes:

@media only screen and (max-width: 640px) {}
@media only screen and (max-width: 800px) {}
@media only screen and (max-width: 1024px) {}
@media only screen and (max-width: 1280px) {}

Remember to define the appropriate CSS styles for each media query. This comprehensive approach ensures that your layout adapts effectively to various screen sizes.
