When using a shape block, the SVG markup is embedded directly in the HTML, eliminating HTTP requests and enabling CSS manipulation. **Performance Benefits**: Inline SVGs reduce server requests, particularly beneficial for icon-heavy layouts. A page with eight icon cards would make eight fewer requests using shape blocks versus image blocks. **Styling Control**: Inline SVGs allow real-time color changes through CSS, theme variable integration, and hover effects that are impossible with image blocks. This enables dynamic theming and responsive design adaptations. **Animation Capabilities**: Shape blocks unlock SVG animation possibilities by making individual SVG elements targetable through CSS and JavaScript. **Tradeoffs**: Shape blocks increase HTML size through code repetition, don't cache as efficiently across pages, require manual updates when changed across multiple locations, and demand more technical knowledge for optimization. ## 🗒️ Notes #### ⏱️ [00:00](https://youtu.be/ZUZMUkoB4lA?t=0) — [H1] Introduction to shape block vs image block question - Key idea: Community question sparked analysis of shape block advantages - Evidence: "I didn't even really think about this as I did it.

While one logo saves one request, imagine eight icon cards—that's eight fewer requests with shape blocks vs image blocks. **Styling Superpowers**: Unlike image blocks, shape blocks let you recolor icons with CSS, integrate theme variables, and add hover effects. Perfect for dark mode toggles or brand color updates. **Animation Ready**: Want animated icons? Shape blocks make individual SVG elements targetable for smooth CSS animations. **Trade-offs to Consider**: You'll get larger HTML files, less efficient caching, and manual updates across multiple instances. Plus, working with SVG code requires a bit more technical comfort. **Bottom Line**: Use shape blocks when you need styling control or animations. Stick with image blocks for complex graphics or frequently updated assets.

And in that video, I [00:07] used the shape block instead of the [00:08] image block for the logo inside of that [00:11] header. And I got a question down in the [00:13] comments about why I used that shape [00:14] block instead of an image block. Now, to [00:16] be fair, I didn't even really think [00:17] about this as I did it. I just kind of [00:19] did it out of a force of habit. But as I [00:21] had to think about it and answer that [00:22] question, I realized there's actually a [00:24] lot of superpowers that come along with [00:26] using the shape block instead of the [00:27] image block. To be fair, there are a [00:29] couple downsides, too. But once you know [00:31] what you can do with the shape block [00:32] that you just can't do with the image [00:34] block, I bet you can find some ways to [00:35] use it more creatively. So, in today's [00:37] video, we're going to go over the [00:38] advantages and disadvantages of the [00:40] shape block and show you a few things [00:41] that you might not know. If that sounds [00:43] interesting to you, then stick around [00:44] and let's get started. Now, the only [00:46] reason why I could use the shape block [00:48] here instead of just the image block is [00:50] that the logo I was using for my website [00:51] was an SVG file. Now, if you don't know [00:54] much about SVG files, those are actually [00:56] vector graphics. Vector graphics have a [00:58] couple benefits to them. The main one [01:00] being that they can scale infinitely [01:02] without ever losing resolution. Unlike a [01:04] raster image like a JPEG or a PNG, [01:07] they're never going to get pixelated [01:08] whether they're 10 pixels or 10,000 [01:10] pixels wide. They can also be a much [01:12] smaller file size depending on exactly [01:14] what the graphic is. But for a simple [01:16] logo or an icon, usually an SVG file is [01:19] going to be smaller than a raster file. [01:21] Now, the image block will allow you to [01:23] use SVGs inside it. So that doesn't [01:25] really answer why I use the shape block [01:26] instead of the image block in this [01:28] scenario. So let's take a look at both [01:30] of these inside of the website and see [01:31] how they differ. So here inside the [01:33] setup, you can see I have two images [01:35] that basically look identical. This [01:37] first one here is using the shape block [01:39] and the second one is using the image [01:41] block, but both are using the exact same [01:43] SVG. And again on the front end, both of [01:46] these look identical. But when we [01:48] inspect the code, we'll see the [01:49] difference here. If I go ahead and [01:51] select the second one, which was using [01:52] the image block, we can see it's using [01:54] the image tag here and it's pointing to [01:56] the source of my SVG image, but the [01:59] shape block outputs the actual SVG [02:01] element. The full SVG markup is all [02:04] directly here inside the HTML. Now, this [02:07] is what we call an inline SVG versus [02:09] like an external SVG like we have inside [02:12] this image block. So, now that you can [02:13] see how these output two different HTML [02:16] tags, let's talk about why this matters. [02:18] Back here inside the editor, I'm going [02:20] to go ahead and get rid of our shape [02:22] element so we only have our image [02:23] element. We'll go ahead and save those [02:25] changes and I'll refresh on the front [02:27] end. Now, here inside the network tab, [02:30] we can see every request that's being [02:32] made in order to load this website. We [02:34] see at the bottom down here that there [02:35] are 17 total requests. But if I go back [02:39] in here and undo those changes, this [02:41] time we'll get rid of our image block [02:42] and go ahead and save those changes. And [02:45] again, we'll refresh. and we'll see the [02:46] number of requests has gone down to 16. [02:49] With the image block, the browser has to [02:51] request that SVG file. But with the [02:53] shape block, the browser doesn't. The [02:55] SVG is already inside the HTML. Now, [02:58] this difference doesn't mean a whole lot [02:59] when we're just talking about one logo. [03:01] But imagine you had a layout with eight [03:03] cards and each one of them had their own [03:04] different icon. If you were to use the [03:06] image block for all those icons, that's [03:08] eight extra requests on your page. But [03:10] if you use the shape block, you wouldn't [03:12] have any extra requests for all those [03:14] icons. Now, reducing the number of [03:16] requests doesn't always speed up your [03:17] website, but it certainly can. And that [03:19] would definitely be the case when you [03:20] had a bunch of simple icons. So, using [03:22] an inline SVG like the shape block [03:25] allows us to do can be one way to speed [03:27] up your page. Now, the second big [03:28] benefit to using the inline SVGs and the [03:31] one that's a little bit more fun is [03:32] inline SVGs give us the ability to style [03:35] those images using just plain CSS. In [03:38] fact, I can show you this here in a [03:40] pretty simple demonstration. If I have [03:42] this simple icon that's just a single [03:44] color, I can use the inline SVG element, [03:47] then use the panels inside generate [03:48] blocks to recolor that icon whatever I [03:51] want. If I use the image block, I [03:53] wouldn't have this ability. If you want [03:55] to get extra fancy, you can use all your [03:57] color variables from your theme inside [03:59] the SVG images and that way it matches [04:01] the theme of your website perfectly and [04:03] if you ever change those brand colors, [04:05] all your icon colors will update with [04:07] it. But it's not just about the color of [04:09] icons. Using the inline SVG means you [04:11] can actually target the elements inside [04:13] that SVG and animate them pretty simply. [04:16] That's actually how I created this [04:17] animated SVG on the homepage of [04:19] Termageddon's website. If you want to [04:21] learn a little bit more about how to [04:23] animate those SVGs, I've left a link [04:25] down in the description for a video from [04:26] Fire Ship that does a really good job of [04:28] showing you how that works. Using inline [04:30] SVGs gives you a whole lot of control [04:32] that you could never have with the image [04:33] block. But of course, web development is [04:36] never black and white, so it comes with [04:37] some drawbacks, too. Inline SVGs are [04:40] going to add more HTML code to your [04:41] page. If you had the same logo or icon [04:44] six times on your page, it's going to be [04:46] repeated six times in your HTML. [04:48] However, if you were using the image [04:49] block, you just have one image that [04:51] keeps getting referenced multiple times. [04:53] So, you might end up with more or less [04:55] code either way you go. It really just [04:57] depends on the situation. The inline [04:59] SVGs and image elements also don't get [05:01] cached the same way. Your browser may [05:03] cache that full HTML page, but it [05:05] doesn't reuse that same HTML when you go [05:08] from one page to the next. With a image [05:10] block, once you cache that image, it can [05:12] be referenced as people visit different [05:13] pages on your website. And let's say you [05:15] use inline SVGs for your logo across a [05:18] bunch of different places on your [05:19] website. Well, if your logo ever needs [05:22] to change, you're going to go have to [05:23] hunt down every single one of those [05:24] instances and replace them manually. If [05:27] you just used the image block and [05:28] referenced a specific SVG file, you [05:31] could go in your media library and [05:32] replace that and it would be instantly [05:34] updated across your entire website. And [05:36] of course, dealing with SVG code is just [05:38] a little bit more technical. It's not [05:40] too bad if you don't mind digging into [05:41] the code, but I know not everyone wants [05:43] to do that and you have to do it a [05:45] little bit more when you're using those [05:46] inline SVGs. Now, I don't think any of [05:48] these are dealreakers for using inline [05:50] SVGs. In fact, I use them quite a bit, [05:52] but it's helpful to know the benefits [05:54] and drawbacks so you know which one to [05:55] use in different situations. Now, if [05:57] you've only used the image block, I'm [05:58] not suggesting you go back to every [06:00] project you've ever done and replace it [06:01] with inline SVGs. However, if you've [06:04] ever thought, "Oh, this would look [06:05] pretty nice in dark mode if I change the [06:07] color of this icon, or you'd like to [06:09] animate it or just change something on [06:11] hover, then the shape block can really [06:12] come in handy." Hopefully, you learned [06:14] something in today's video. If you did, [06:16] I would really appreciate a thumbs up.
