As I scroll down, this image [00:03] that is currently split into four [00:05] squares is going to merge back into one. [00:08] When I scroll back down, it splits up [00:10] again. Why would this be useful? Maybe [00:12] you just want the image to focus on [00:14] particular aspects or you just want to [00:16] give a slow reveal of some details. But [00:19] as you scroll down, that image is going [00:21] to merge into one. It's the same image. [00:24] And with a little bit of CSS, we are [00:26] enabling this to split up or create a [00:28] masking effect. And I think this is [00:30] really, really cool. And this could add [00:32] something different to your hero banners [00:34] or some other part of your page. Now, I [00:37] do want to point out this only works for [00:39] the desktop. And I have enabled the code [00:41] not to do this for the mobile because [00:43] sometimes depending on the mobile, it [00:45] doesn't work very well. But for the [00:47] desktop, you can definitely have this [00:49] effect. [00:51] Let's get into the nitty-gritty of it. [00:53] We have a container. We have an image. I [00:55] have another child container. Inside of [00:57] it, I've just popped in a heading, a bit [00:58] of text, and a button. You can ignore [01:00] everything over here. What we're [01:02] focusing on the image. And it is just [01:05] one image. This is not four separate [01:07] images. One image. I've set it to be 500 [01:10] pixels in width and 500 in height. Set [01:12] it to be a cover, bottom right, you [01:14] know, whatever you want to do. And I've [01:16] intentionally picked an image where we [01:18] had uh people so that when we did have [01:20] the gap, it literally looked like we had [01:23] individual images there. Let's go to the [01:25] advanced tab. There is no class name. [01:28] And when we go to the custom CSS, here's [01:30] where the magic happens. Don't worry [01:32] about all of these X's. When it says [01:34] unknown rule or whatever like that, this [01:36] works absolutely fine. Okay. What this [01:39] is going to do is enable that image to [01:42] mask or have this staggered white kind [01:45] of border thingy floating in on the [01:48] image. And then as you scroll up or [01:51] scroll down, in fact, the gap there is [01:54] going to shrink. Now, I've set my gap to [01:56] be 20 pixels. And I do want to point out [01:58] if I go to this container, it doesn't [02:00] matter what gap I've got set here [02:02] whatsoever. I mean, I could go in and [02:04] set this to be zero for the container. [02:06] All it's going to do is move the image [02:08] and the child can child container [02:11] slightly closer. It does not influence [02:13] the gap inside of that image. Let's just [02:16] go back to the CSS code. So, whatever [02:18] value I set here, I need to just mirror [02:20] it over here as well. Just remember [02:22] that. And it should be pretty [02:24] self-explanatory because I've got 20 [02:25] pixel and 20 pixel. And then down here [02:28] again, just make sure you mirror that [02:30] value. Now the other thing you do want [02:32] to take into account is at what point do [02:34] you want it to start merging and then be [02:38] fully merged. So I've got cover. Now you [02:41] do have entry. So this would be now [02:43] based on the top of the image or you [02:45] could put the word exit and that would [02:47] be based on the bottom. But I have found [02:49] and I did a bit of testing with this [02:51] cover works much better. Cover is based [02:54] on the central point of your image. So, [02:56] what I'm saying is when this image is at [02:58] 45% of the screen, so roughly somewhere [03:02] around here, and you can see it's [03:04] starting to merge. And when we get to [03:05] 60%, which is here, so that's the [03:07] middle. That middle now is at 60%. This [03:10] is the middle of my screen just over [03:12] here where you can see my mouse. So, [03:14] round about somewhere around, let's just [03:16] get it back again. You can just see it [03:17] there at the 60% mark. I want it now to [03:20] be basically fully merged up. So, you [03:23] can now see the image fully. But if you [03:25] want it to break back down where as you [03:27] scroll upwards because you got to always [03:29] think about the movement of your mouse [03:30] but as you scroll upwards so you're now [03:32] going higher in the page it kind of the [03:34] mask reappears. Am I making sense what [03:37] I'm trying to get across to you. All [03:39] you've got to do is decide on at what [03:42] point do you want it to start merging or [03:44] not and when do you want it to be fully [03:46] merged and how big do you want the gap. [03:49] So if I was to go in here and now I set [03:51] that to be 50. are very spaced out. Just [03:54] make sure you put 50 pixel over there. [03:56] Make sure you do 50 pixel here. Oh, and [03:58] sorry, do it over there as well. So, [04:00] what happens is when you get to mobile, [04:02] you will see this. Now, I have not set [04:05] my image size or anything like that, but [04:07] I'm just want to get you to I mean, [04:09] look, I'll do it now because I know [04:10] someone's going to say, "Oh, that [04:11] doesn't look quite right." So, let's [04:12] just make the image be something like [04:14] that. Now when you are looking at it [04:16] with edit with elementor it might [04:18] sometimes look like it was merging but [04:21] it never was spoton or proper and that [04:23] is why inside of this code if we go back [04:25] to it I've basically said just leave it [04:27] as a fixed but if maybe for the mobile [04:31] you don't want that and you do want it [04:33] to be fully merged just go and set that [04:35] to be zero down there. Okay, just make [04:37] sure you set that bit to zero right at [04:39] the bottom. So on the desktop you will [04:41] still see it and it's still going to [04:42] work exactly as I've described. So as [04:44] you scroll up it merges or the mask [04:47] disappears. But on the mobile you could [04:49] either have the gap or not. Or you could [04:51] even set it to be smaller. I mean you [04:53] could even go for not 50. I went for [04:55] five, you know. No, not five. What am I [04:57] doing? Go for five. Right. So you do [04:59] have a bit of control but I'm just going [05:01] to leave it like that. There's the code. [05:04] I will stick that in the video [05:06] description. I hope you like that [05:08] because I'm not saying do this [05:10] throughout your website everywhere. [05:12] Sometimes entrance animations or even [05:14] any form of animation can get noisy and [05:16] busy on your website. But if you just [05:19] want to do something a little different [05:21] because you let's just pretend this was [05:23] your hero banner. I'll let you play [05:24] around with it. Stick it into chat GPT [05:26] if you want to tinker with it. Let me [05:28] know in the comments what you think [05:29] about this. I'm in from Web Squadron. [05:32] Make sure you like, subscribe, share, [05:33] and follow. Make sure you sign up for [05:35] our YouTube channel for exclusive [05:37] videos. But I really hope this just [05:39] makes you think a little bit differently [05:42] about the way you're building and the [05:43] way you're doing things. Take care. I'll [05:45] see you soon. Bye.

As I scroll down, this image that is currently split into four squares is going to merge back into one. When I scroll back down, it splits up again. Why would this be useful? Maybe you just want the image to focus on particular aspects or you just want to give a slow reveal of some details. But as you scroll down, that image is going to merge into one. It's the same image. And with a little bit of CSS, we are enabling this to split up or create a masking effect. And I think this is **[00:30]** really, really cool. And this could add something different to your hero banners or some other part of your page. Now, I do want to point out this only works for the desktop. And I have enabled the code not to do this for the mobile because sometimes depending on the mobile, it doesn't work very well. But for the desktop, you can definitely have this effect. Let's get into the nitty-gritty of it. We have a container. We have an image. I have another child container. Inside of it, I've just popped in a heading, a bit of text, and a button. You can ignore everything over here. What we're **[01:02]** focusing on the image. And it is just one image. This is not four separate images. One image. I've set it to be 500 pixels in width and 500 in height. Set it to be a cover, bottom right, you know, whatever you want to do. And I've intentionally picked an image where we had uh people so that when we did have the gap, it literally looked like we had individual images there. Let's go to the advanced tab. There is no class name. And when we go to the custom CSS, here's where the magic happens. Don't worry about all of these X's. When it says **[01:34]** unknown rule or whatever like that, this works absolutely fine. Okay. What this is going to do is enable that image to mask or have this staggered white kind of border thingy floating in on the image. And then as you scroll up or scroll down, in fact, the gap there is going to shrink. Now, I've set my gap to be 20 pixels. And I do want to point out if I go to this container, it doesn't matter what gap I've got set here whatsoever. I mean, I could go in and **[02:04]** set this to be zero for the container. All it's going to do is move the image and the child can child container slightly closer. It does not influence the gap inside of that image. Let's just go back to the CSS code. So, whatever value I set here, I need to just mirror it over here as well. Just remember that. And it should be pretty self-explanatory because I've got 20 pixel and 20 pixel. And then down here again, just make sure you mirror that value. Now the other thing you do want to take into account is at what point do **[02:34]** you want it to start merging and then be fully merged. So I've got cover. Now you do have entry. So this would be now based on the top of the image or you could put the word exit and that would be based on the bottom. But I have found and I did a bit of testing with this cover works much better. Cover is based on the central point of your image. So, what I'm saying is when this image is at 45% of the screen, so roughly somewhere around here, and you can see it's starting to merge. And when we get to **[03:05]** 60%, which is here, so that's the middle. That middle now is at 60%. This is the middle of my screen just over here where you can see my mouse. So, round about somewhere around, let's just get it back again. You can just see it there at the 60% mark. I want it now to be basically fully merged up. So, you can now see the image fully. But if you want it to break back down where as you scroll upwards because you got to always think about the movement of your mouse but as you scroll upwards so you're now going higher in the page it kind of the mask reappears. Am I making sense what **[03:37]** I'm trying to get across to you. All you've got to do is decide on at what point do you want it to start merging or not and when do you want it to be fully merged and how big do you want the gap. So if I was to go in here and now I set that to be 50. are very spaced out. Just make sure you put 50 pixel over there. Make sure you do 50 pixel here. Oh, and sorry, do it over there as well. So, what happens is when you get to mobile, you will see this. Now, I have not set my image size or anything like that, but **[04:07]** I'm just want to get you to I mean, look, I'll do it now because I know someone's going to say, "Oh, that doesn't look quite right." So, let's just make the image be something like that. Now when you are looking at it with edit with elementor it might sometimes look like it was merging but it never was spoton or proper and that is why inside of this code if we go back to it I've basically said just leave it as a fixed but if maybe for the mobile you don't want that and you do want it to be fully merged just go and set that to be zero down there. Okay, just make sure you set that bit to zero right at **[04:39]** the bottom. So on the desktop you will still see it and it's still going to work exactly as I've described. So as you scroll up it merges or the mask disappears. But on the mobile you could either have the gap or not. Or you could even set it to be smaller. I mean you could even go for not 50. I went for five, you know. No, not five. What am I doing? Go for five. Right. So you do have a bit of control but I'm just going to leave it like that. There's the code. I will stick that in the video description. I hope you like that because I'm not saying do this **[05:10]** throughout your website everywhere. Sometimes entrance animations or even any form of animation can get noisy and busy on your website. But if you just want to do something a little different because you let's just pretend this was your hero banner. I'll let you play around with it. Stick it into chat GPT if you want to tinker with it. Let me know in the comments what you think about this. I'm in from Web Squadron. Make sure you like, subscribe, share, and follow. Make sure you sign up for our YouTube channel for exclusive videos. But I really hope this just makes you think a little bit differently **[05:42]** about the way you're building and the way you're doing things. Take care. I'll see you soon. Bye. [Music]
