reinitialize swiper over mouseleave works but its lost css styling

Assistant
When you destroy and reinitialize Swiper on `mouseleave`, it removes all styles and resets the DOM. That's why your Swiper loses its CSS styling. Instead of destroying and reinitializing Swiper, you can pause and restart autoplay while preserving all styles.

### Solution: Stop/Resume Autoplay Without Destroying Swiper
Modify your `mouseleave` event like this:

#### **Fix: Stop Autoplay on Hover Without Destroying Swiper**

if (jQuery('.swiperslides').length) {
    var swiper = new Swiper(".swiperslides", {
        slidesPerView: "auto",
        centeredSlides: true,
        spaceBetween: 30,
        loop: true,
        speed: 6000, // Transition speed
        loopAdditionalSlides: 3, // Add duplicate slides for seamless looping
        allowTouchMove: false,
        loopFillGroupWithBlank: false,
        autoplay: {
            delay: 1, // VERY short delay for smoothness
            disableOnInteraction: false,
            stopOnLastSlide: false, // Ensure it loops continuously
        },
        on: {
            beforeInit: function (swiper) {
                swiper.wrapperEl.style.transitionTimingFunction = "linear";
            },
            init: function () {
                console.log("Swiper initialized");

                const swiperEl = document.querySelector('.swiperslides');

                // Stop autoplay and disable transitions on mouseenter
                swiperEl.addEventListener('mouseenter', () => {
                    swiper.autoplay.stop(); // Stop autoplay
                    swiper.setTransition(0); // Remove transition effects
                    console.log("Autoplay stopped and transitions disabled on mouseenter");
                });

                // Resume autoplay on mouseleave
                swiperEl.addEventListener('mouseleave', () => {
                    console.log("Mouseleave event triggered");
                    swiper.setTransition(swiper.params.speed); // Restore transition
                    swiper.autoplay.start(); // Restart autoplay
                    console.log("Autoplay resumed on mouseleave");
                });
            }
        },
        breakpoints: {
            0: {
                slidesPerView: 1.2,
                spaceBetween: 10,
            },
            1024: {
                slidesPerView: 3,
                spaceBetween: 30,
            },
        },
    });

    swiper.autoplay.start(); // Ensure autoplay is initially started
}

### **Why This Works:**
– **No need to destroy Swiper:** Keeps the original styling intact.
– **Stops autoplay on hover:** `swiper.autoplay.stop();`
– **Disables transitions on hover:** `swiper.setTransition(0);`
– **Restores autoplay smoothly on mouseleave:** `swiper.setTransition(swiper.params.speed);`

This method ensures that the Swiper continues looping seamlessly without losing styles or breaking animations. 🚀

User
but above solution not immediate stop autopla on mouseover
Assistant
If you want to **immediately** stop autoplay on `mouseenter`, instead of just stopping autoplay, you also need to set the `speed` to `0`. That way, Swiper stops moving as soon as you hover over it.

                    swiper.setTranslate(swiper.translate); // Keep it frozen in place
                    console.log("Immediate stop on hover");
                });

                swiperEl.addEventListener('mouseleave', () => {
                    console.log("Resuming autoplay...");
                    swiper.setTransition(swiper.params.speed); // Restore speed
                    swiper.autoplay.start(); // Restart autoplay
                });
            }
        },

            },
        },
    });

    swiper.autoplay.start();
}

### **🔥 Why This Works**
✅ **Stops Immediately on Hover:**
– `swiper.setTransition(0);` removes animations.
– `swiper.setTranslate(swiper.translate);` freezes the position.

✅ **Resumes Smoothly on Mouse Leave:**
– `swiper.setTransition(swiper.params.speed);` restores animation.
– `swiper.autoplay.start();` resumes autoplay.

—

### **🎯 Expected Behavior**
✔ **Swiper stops instantly** when hovered.
✔ **Swiper resumes smoothly** when the mouse leaves.
✔ **No reinitialization needed** (so styling stays intact).

This should give you the **perfect smooth and immediate stopping effect**! 🚀

If the autoplay is not stopping immediately on hover, we can use a more forceful approach by setting `swiper.autoplay.running = false;` to immediately halt movement.

            },
        },
    });

    swiper.autoplay.start();
}

### **🚀 Why This Works**
✔ **Forcefully stops autoplay instantly** using `swiper.autoplay.running = false;`.
✔ **Freezes the slider at the current position** using `swiper.setTranslate(swiper.translate);`.
✔ **Prevents unwanted animations** with `swiper.setTransition(0);`.
✔ **Smoothly resumes autoplay** on `mouseleave`.

### **🔥 Expected Behavior**
✔ **Immediate stop on hover** (no lag).
✔ **Smooth autoplay restart when the mouse leaves**.
✔ **No need to destroy or reinitialize Swiper** (CSS remains intact).

This should **definitely work now**! 🚀 Try it and let me know! 😊

If the autoplay isn't stopping immediately, we need a stronger approach by completely disabling Swiper’s animation cycle.

### **🚀 Why This Works**
✅ **Forces an immediate stop** with `transition: none !important;`.
✅ **Prevents unwanted sliding** by freezing `transform: translate3d()`.
✅ **Uses a CSS class (`swiper-paused`)** to instantly apply the effect.
✅ **Autoplay resumes smoothly** on `mouseleave`.

### **🔥 Expected Behavior**
✔ **Swiper stops immediately on hover.**
✔ **No animation delay, no lag, no sliding.**
✔ **Autoplay resumes smoothly when you move the mouse away.**

Yes its works but when mouse leave its autoplay speed less than 6000 for some time

Great! Now to fix the **autoplay speed issue after mouse leave**, we need to **force-reset the transition speed** when restarting autoplay.

### **🔧 Why This Fix Works**
✔ **Instant stop on hover** → `transition: none !important;`.
✔ **Prevents autoplay slowdown** → `swiper.params.speed = 6000;`.
✔ **Ensures smooth restart** → `swiper.setTransition(0);`.
✔ **Prevents animation lag** → `swiper.setTranslate(swiper.translate);`.

Now, **Swiper will resume at full speed (6000ms) immediately** after mouse leave without any slowdown.

**Try this and let me know if it works perfectly now! 🚀**

but now auto not start

Got it! The issue is that `swiper.setTransition(0);` and `swiper.setTranslate(swiper.translate);` interfere with autoplay restarting. Let's refine the approach while ensuring autoplay resumes correctly at **full speed**.
