Yes→Re-detect Screen Size

↩No +---> Back to Apply Media Queries

The theme loads base styles, detects screen size, applies media queries to adjust layout, and re-renders responsively on window resize.

Execution Sample

Wordpress

@media (max-width: 600px) {
  body {
    background-color: lightblue;
  }
}

This CSS changes the background color to light blue when the screen width is 600px or less.

Execution Table

Step	Screen Width (px)	Media Query Condition	Action Taken	Visual Effect
1	1024	max-width: 600px? False	Apply base styles only	Normal desktop layout with default colors
2	600	max-width: 600px? True	Apply media query styles	Background changes to light blue, layout adjusts for small screen
3	480	max-width: 600px? True	Apply media query styles	Background remains light blue, layout optimized for smaller devices
4	800	max-width: 600px? False	Revert to base styles	Background returns to default, layout adjusts for medium screen
5	400	max-width: 600px? True	Apply media query styles	Background changes to light blue again, layout for small screen

💡 Execution continues as user resizes window; styles update dynamically based on screen width.

Variable Tracker

Variable	Start	After Step 1	After Step 2	After Step 3	After Step 4	After Step 5
screenWidth	N/A	1024	600	480	800	400
mediaQueryApplies	N/A	False	True	True	False	True
backgroundColor	default	default	lightblue	lightblue	default	lightblue

Key Moments - 2 Insights

Why does the background color change only when the screen width is 600px or less?

Because the media query condition 'max-width: 600px' is true only when the screen width is 600px or less, as shown in the execution_table rows 2, 3, and 5.

What happens when the user resizes the window from 480px to 800px?

The media query condition becomes false, so the styles revert to base styles, changing the background color back to default, as seen in execution_table row 4.

Visual Quiz - 3 Questions

Look at the execution_table, what is the backgroundColor at step 3 when screenWidth is 480?

A lightblue

B white

C default

D darkblue

💡 Hint

Check the 'backgroundColor' value in variable_tracker after Step 3.

At which step does the media query condition become false after being true?

A Step 2

B Step 3

C Step 4

D Step 5

💡 Hint

Look at the 'mediaQueryApplies' row in variable_tracker and execution_table conditions.

If the max-width in the media query changed to 500px, how would the background color behave at step 2 (600px)?

A It would be lightblue

B It would remain default

C It would be darkblue

D It would be transparent

💡 Hint

Consider if 600px satisfies 'max-width: 500px' condition.

Concept Snapshot

Responsive Theme Patterns in WordPress:
- Use CSS media queries to detect screen size.
- Apply base styles first, then override with media queries.
- Media queries adjust layout and styles for different devices.
- Browser re-applies styles on window resize.
- Example: '@media (max-width: 600px) { ... }' changes styles for small screens.

Full Transcript

Responsive theme patterns in WordPress use CSS media queries to adapt the website layout and styles based on the screen size. The browser first loads base styles, then checks the screen width. If the screen width matches a media query condition, such as max-width 600px, it applies the specified styles, like changing background color or adjusting layout. When the user resizes the window, the browser re-evaluates the conditions and updates styles accordingly. This ensures the website looks good on desktops, tablets, and phones by dynamically changing styles as shown in the execution steps and variable changes.
