Animated loader · gpt-oss-safeguard-20b

We need to build an index.html with GSAP animation, with shapes and dots. We'll use GSAP's timeline. Need pause/resume/restart controls.

We can create a simple container with a group of shapes maybe 4 rounded rectangles that animate scale and position and border radius.

Also a row of five dots that animate opacity or position in staggered fashion.

Implement controls as buttons: Pause/Resume and Restart.

The script uses gsap.min.js loaded from local. We'll add a script src="gsap.min.js" then our code.

Let's craft index.html with dark background: background:#111.

In CSS, create container centered with flex. Use .shape elements with width/height, border radius etc.

Use GSAP to animate shapes: timeline with repeat: -1, yoyo? maybe not; but we want smooth transition without abrupt jump. Use timeline with .to() each shape.

Also dots: create 5 span elements with class dot, styled as circles with size, background color, margin.

Animate opacity: timeline.stagger from 0 to 1 and back.

Use timeline.reversed? pause/resume using timeline.pause(), .play().

Restart: set timeline.restart() or .seek(0).restart().

Make sure the controls reflect state: Pause button toggles to Resume.

Implement using DOMContentLoaded.

Let's produce index.html content.

Before writing, maybe check if gsap.min.js is present in current directory. We'll list.

We need to create index.html with GSAP animation. We'll write a simple HTML file. Let's design.

We need dark background, group of rounded geometric shapes that smoothly change scale, position, corner radius. And row of five dots with staggered motion or opacity.

Use GSAP timeline with repeat: -1.

Include controls: Pause/Resume button and Restart.

We must use the local gsap.min.js included via <script src="gsap.min.js"></script>.

Make sure timeline is stored globally and accessible to controls.

We also need to sample timeline at several moments; but we just need to run and verify, not produce logs.

Let's write HTML with style. Use a container div centered.

We'll create shapes using div elements with border-radius etc. Maybe a set of three squares? But requirement: rounded geometric shapes: could be circles? maybe squares with rounded corners? We'll create several divs with absolute positioning.

Simplify: create 3 shapes (rectangles) that animate scale, position, border-radius.

Also row of five dots: small circles with staggered opacity or vertical movement.

Use gsap.to with stagger.

Timeline: 4-6 seconds.

Add controls: Pause/Resume button that toggles, and Restart button.

Implement.

Let's draft content.

We wrote a file. Need to verify functionality with browser. Let's run browser inspect to see if page loads, but we cannot open actual browser? We have browser tool. Let's inspect? We'll just reload and screenshot maybe. But we need to verify timeline etc. Use browser tool to open? We'll run reload and then screenshot maybe.

But first ensure script loads gsap.min.js from file. Let's check file size? but fine.

We need to ensure smooth loop without growing instances. We used repeat:-1 on timeline; we used tl.to(...). But we also used a nested to for dots with repeat:-1 in stagger; that might cause duplicate. Actually we added to tl a to with dots that has repeat:-1, which will create separate animation each time? Might cause duplication. Instead we can animate dots via tl.to with yoyo:true and repeat:-1, but we might need separate timeline for dots? We'll keep it.

Also the color property changes not recognized because CSS uses background not color. We used 'color' property incorrectly. Should animate backgroundColor. We'll fix.

Also ensure shapes stay centered: shapes positioned absolute relative to loader. We use top? not necessary.

Let's edit index.html: change 'color' to 'backgroundColor'. Also ensure initial background color maybe 121212; shape colors defined via inline style? We'll set CSS. But easier to animate using backgroundColor.

Let's patch.

Also the dots animation uses yoyo true and repeat -1 inside a to. But we also set repeat:-1 on main timeline. That may produce nested repeat but fine. However the dot opacity will go to 0 then back to 1 due to yoyo. But we also set repeat -1 again? Wait we used yoyo:true repeat:-1 inside stagger property; not repeat on the entire timeline.

But we may have duplicate animations each time timeline restarts? But repeat:-1 means timeline loops but same animations reapply? That should be okay.

Let's patch color property.

Also we may want to set initial opacity of dots to 1. In CSS, default is 1.

Also we might want to animate dot translation maybe. We used yoyo true, so it will oscillate. We'll test.

Also ensure shapes have border radius defined. We used 10% initial. Good.

Let's patch.

Also we may need to set pointer events for buttons. It's fine.

Let's edit.
