Our **Custom Block** allows you to insert and edit your own **HTML, CSS, or JavaScript**, giving advanced users the ability to create completely unique elements that go beyond standard templates. Whether you want to fine-tune styling, integrate third-party widgets, or add interactive components, **custom code blocks unlock endless possibilities**. For expert tips on making the most of these blocks, check out our custom block guide to take your page to the next level. ### **How to Use Custom Code Blocks** 1. **Navigate to the Builder** - Open your website builder and click on **+ Add Blocks**. - Select **Custom** from the list of available blocks. 2. **Start Writing Your Code** - Once added, the **Custom Block** is fully editable. - You can write your own **HTML, CSS, or JavaScript** directly inside the block. 3. **Manage Block Placement** - By default, the custom block will be added to the **bottom of your block stack**. - Simply drag and rearrange it to position it wherever you need. With custom code blocks, you can break free from limitations and **design a site that truly reflects your vision**. Whether you're embedding dynamic content, adjusting styles, or adding custom scripts, this feature gives you the tools to build something truly unique. 🚀   ### **Important Reminder:** Since custom code blocks offer **limitless possibilities** and allow you to code freely, our **Customer Service Team is unable to provide support** for custom code. Please keep this in mind when using custom blocks, and ensure you’re comfortable troubleshooting any issues that may arise. That said, we encourage you to explore and experiment—your creativity is the only limit!         - [Startups.com Customer Support](https://help.startups.com/knowledge/startups-com-customer-support?hsLang=en#main-content) - [Account Subscription](https://help.startups.com/knowledge/startups-com-customer-support?hsLang=en#account-subscription) - [Membership Features](https://help.startups.com/knowledge/startups-com-customer-support?hsLang=en#membership-features) - [Investor Matching](https://help.startups.com/knowledge/startups-com-customer-support?hsLang=en#investor-matching) - [Perks and Benefits](https://help.startups.com/knowledge/startups-com-customer-support?hsLang=en#perks-and-benefits) - [Startups.com Site Content Help](https://help.startups.com/knowledge/startups-com-site-content-help?hsLang=en#main-content) - [General](https://help.startups.com/knowledge/startups-com-site-content-help?hsLang=en#general) - [Fundable](https://help.startups.com/knowledge/fundable?hsLang=en#main-content) - [General](https://help.startups.com/knowledge/fundable?hsLang=en#general) - [Getting Started on Fundable](https://help.startups.com/knowledge/fundable?hsLang=en#getting-started-on-fundable) - [Equity Campaigns](https://help.startups.com/knowledge/fundable?hsLang=en#equity-campaigns) - [Creating a Fundable Profile](https://help.startups.com/knowledge/fundable?hsLang=en#creating-a-fundable-profile) - [Investors](https://help.startups.com/knowledge/fundable?hsLang=en#investors) - [Legal](https://help.startups.com/knowledge/fundable?hsLang=en#legal) - [Payments & Fees](https://help.startups.com/knowledge/fundable?hsLang=en#payments-fees) - [Clarity.fm](https://help.startups.com/knowledge/clarity-fm?hsLang=en#main-content) - [General](https://help.startups.com/knowledge/clarity-fm?hsLang=en#general) - [Calls](https://help.startups.com/knowledge/clarity-fm?hsLang=en#calls) - [Member FAQs](https://help.startups.com/knowledge/clarity-fm?hsLang=en#member-faqs) - [Expert FAQs](https://help.startups.com/knowledge/clarity-fm?hsLang=en#expert-faqs) - [Privacy & Security](https://help.startups.com/knowledge/clarity-fm?hsLang=en#privacy-security) - [Payments & Fees](https://help.startups.com/knowledge/clarity-fm?hsLang=en#payments-fees) - [Getting Started on Clarity](https://help.startups.com/knowledge/clarity-fm?hsLang=en#getting-started-on-clarity) - [Your Clarity Account](https://help.startups.com/knowledge/clarity-fm?hsLang=en#your-clarity-account) - [Frequently Asked Questions](https://help.startups.com/knowledge/clarity-fm?hsLang=en#frequently-asked-questions) - [Bizplan](https://help.startups.com/knowledge/bizplan?hsLang=en#main-content) - [Customizing Plan](https://help.startups.com/knowledge/bizplan?hsLang=en#customizing-plan) - [Getting Started](https://help.startups.com/knowledge/bizplan?hsLang=en#getting-started) - [Managing Account](https://help.startups.com/knowledge/bizplan?hsLang=en#managing-account) - [Finance](https://help.startups.com/knowledge/bizplan?hsLang=en#finance) - [Support](https://help.startups.com/knowledge/bizplan?hsLang=en#support) - [Companies](https://help.startups.com/knowledge/bizplan?hsLang=en#companies) - [Publishing](https://help.startups.com/knowledge/bizplan?hsLang=en#publishing) - [Launchrock](https://help.startups.com/knowledge/launchrock?hsLang=en#main-content) - [Custom URLs / DNS Settings / Using Your Domain](https://help.startups.com/knowledge/launchrock?hsLang=en#custom-urls-dns-settings-using-your-domain) - [General Questions](https://help.startups.com/knowledge/launchrock?hsLang=en#general-questions) - [Getting Started on Launchrock](https://help.startups.com/knowledge/launchrock?hsLang=en#getting-started-on-launchrock) - [Video Tutorials](https://help.startups.com/knowledge/launchrock?hsLang=en#video-tutorials) - [Your Launchrock Account](https://help.startups.com/knowledge/launchrock?hsLang=en#your-launchrock-account) - [Payments & Fees](https://help.startups.com/knowledge/launchrock?hsLang=en#payments-fees) - [Blog](https://help.startups.com/blog) [![Chill listening crop-3](https://help.startups.com/hs-fs/hubfs/startupscom-logo-420.png?width=84&height=24&name=startupscom-logo-420.png "Chill listening crop-3")](https://startups.com) Copyright © 2026, Startups.com
