What is the precise functioning of CSS Media Query?

Imagine having 2 separate CSS files, desktop.css and ipad.css, both being used on the same HTML page.

In desktop.css, we have a pseudo div defined like this:

div.someClass{float:left;overflow:hidden;height:100px}

Now, if the user resizes the browser to iPad size and ipad.css is applied, what happens?

Do the properties from desktop.css still apply or are they completely replaced by the properties in ipad.css?

For example, if I want to change the overflow property to 'visible' in ipad.css, do I need to explicitly specify it? Or can I simply define it like this within ipad.css:

div.someClass{float:left;height:100px}

Will the default value of overflow: visible be automatically applied to the div?

Answer №1

@testndtv; make sure to include the overflow:visible property in your ipad.css file. This is essential because the media query will only detect the screen resolution and apply the corresponding css styles based on that. Therefore, we need to override any existing properties in the ipad.css from the activated one.

To update your ipad.css, use the following code snippet:

div.someClass{float:left;overflow:visible;height:100px}

Answer №2

The C in CSS stands for Cascading. When the styles from ipad.css are loaded after and have higher specificity, they will take precedence and be applied.

If a property is not defined in ipad.css but is in desktop.css for the same element (assuming you load desktop.css first), it will default to the rules set in desktop.css.

Answer №3

The way you structure your queries will determine the outcome. It is possible to achieve both methods.
