Building Responsive Layouts: A Guide to Breakpoints, Font Sizing, and Blur Effects

positioning

What is positioning? This determines how an element is positioned on the web page.

Types of Positioning:

Absolute position
Allows complete control over the element's location on the page, independent of the normal document flow (like "god mode"). However, other elements will ignore it and potentially overlap.

Relative position
Positions the element relative to its normal position in the document flow. Great for when you want an element to shift slightly based on its surroundings (e.g., a parent element). Unlike absolute positioning, other elements will still consider it.

Unset option
Resets the element's position back to its normal position in the document flow. This removes any previously applied positioning (absolute or relative) and makes the element inherit its properties from the parent element.

Responsive sizes
Here, you define your responsive breakpoints for different screen sizes:
Sm: Small - 360px wide by 800px tall
Md: Medium - 768px wide by 800px tall
Lg: Large - 1024px wide by 800px tall
Xl: Extra Large - 1280px wide by 800px tall

Font Sizes

Use "em" for fonts: Recommends using "em" units for font sizes as they allow for easier scaling in responsive design.
Growing Default Font Size: While it's possible to increase the default font size for responsive design, "em" units offer more flexibility.

Blure background
This section provides code snippets for blurring a background with different filter options (opacity, brightness) but needs correction in syntax:

Filter: opacity(X,X);
-webkit-filter:opacity(X,X);
-webkit-filter:brightness(X);
-webkit-filter:brightness(X);

                    Then blure it!

Filter: Use opacity(value) only once. Here it's repeated.
Vendor Prefixes: For broader compatibility, add -webkit-filterbefore the standard filter property.
Clarity: Mention that "X" needs to be replaced with the desired value for opacity and brightness (e.g., opacity(0.5) for 50% opacity).
