Simple Custom Error Messages With Pure CSS

Welcome to a quick tutorial on how to create custom error messages with pure CSS. By now, you should have experienced the intrusive default Javascript alert box. Every time it shows up, users get scared away.

We can create a custom non-intrusive error message with HTML .

Yep, it is that simple. Let us “improve and package” this simple error notification bar so you can reuse it easily in your project – Read on!

ⓘ I have included a zip file with all the source code at the start of this tutorial, so you don’t have to copy-paste everything… Or if you just want to dive straight in.

TABLE OF CONTENTS

DOWNLOAD & NOTES

Firstly, here is the download link to the example code as promised.

QUICK NOTES

If you spot a bug, feel free to comment below. I try to answer short questions too, but it is one person versus the entire world… If you need answers urgently, please check out my list of websites to get help with programming.

EXAMPLE CODE DOWNLOAD

Click here to download the source code, I have released it under the MIT license, so feel free to build on top of it or use it in your own project.

CSS-ONLY ERROR NOTIFICATIONS

Let us start with the raw basics by creating notification bars with just pure CSS and HTML.

1) BASIC NOTIFICATION BAR

1A) THE HTML

 
Information message
 
Successful message
 
Warning message
 
Error message

That is actually all we need to create a custom error message, an HTML with the notification message inside. Take note of the bar and info | success | warn | error CSS classes – We will use these to build the notification bar.

1B) THE CSS

/* (A) THE BASE */ .bar < padding: 10px; margin: 10px; color: #333; background: #fafafa; border: 1px solid #ccc; >/* (B) THE VARIATIONS */ .info < color: #204a8e; background: #c9ddff; border: 1px solid #4c699b; >.success < color: #2b7515; background: #ecffd6; border: 1px solid #617c42; >.warn < color: #756e15; background: #fffbd1; border: 1px solid #87803e; >.error

The CSS is straightforward as well –

• .bar is literally the “basic notification bar” with padding, margin, and border.
• .info | .success | .warn | .error sets various different colors to fit the “level of notification”.

Feel free to changes these to fit your own website’s theme.

1C) THE DEMO

2) ADDING ICONS

2A) THE HTML

To add icons to the notification bar, we simply prepend the messages with &#XXXX . For those who do not know – That &#XXXX is a “native HTML symbol”, no need to load extra libraries. Do a search for “HTML symbols list” on the Internet for a whole list of it.

P.S. Check out Font Awesome if you want more icon sets.

2B) THE CSS

Just a small addition to position the icon nicely.

2C) THE DEMO

JAVASCRIPT ERROR NOTIFICATIONS

The above notification bars should work sufficiently well, but here are a few small improvements if you are willing to throw in some Javascript.

3) ADDING CLOSE BUTTONS

3A) THE HTML

Not much of a difference here, except that we now add a that will act as the close button.

3B) THE CSS

/* (D) CLOSE BUTTON */ .bar < position: relative; >div.close

There is not much added to the CSS as well. We simply position the close button to the right of the notification bar, and that’s about it.

3C) THE DEMO

ℹ Information message

4) PACKAGED ERROR NOTIFICATIONS

4A) THE HTML

• target Target HTML container to generate the error message.
• msg The error or notification message.
• lvl Optional, error level.

4B) THE JAVASCRIPT

function ebar (instance) < // target : target html container // msg : notification message // lvl : (optional) 1-info, 2-success, 3-warn, 4-error // (A) CREATE NEW NOTIFICATION BAR let bar = document.createElement("div"); bar.classList.add("bar"); // (B) ADD CLOSE BUTTON let close = document.createElement("div"); close.innerHTML = "X"; close.classList.add("close"); close.onclick = () =>bar.remove(); bar.appendChild(close); // (C) SET "ERROR LEVEL" if (instance.lvl) < let icon = document.createElement("i"); icon.classList.add("ico"); switch (instance.lvl) < // (C1) INFO case 1: bar.classList.add("info"); icon.innerHTML = "ℹ"; break; // (C2) SUCCESS case 2: bar.classList.add("success"); icon.innerHTML = "☑"; break; // (C3) WARNING case 3: bar.classList.add("warn"); icon.innerHTML = "⚠"; break; // (C4) ERROR case 4: bar.classList.add("error"); icon.innerHTML = "☓"; break; >bar.appendChild(icon); > // (D) NOTIFICATION MESSAGE let msg = document.createElement("span"); msg.innerHTML = instance.msg; bar.appendChild(msg); // (E) ADD BAR TO CONTAINER instance.target.appendChild(bar); >

This may look complicated, but this function essentially just creates all necessary notification bar HTML.

4C) THE DEMO
