As a full-stack developer with over 15 years of experience building complex web and mobile applications, few things irk me more than poorly designed buttons. You can have the most sophisticated UX and rock-solid code, but if your buttons look like afterthoughts, users simply won‘t click.
So today, I‘m breaking down everything I‘ve learned over my career about styling buttons that users love with CSS borders.
My goal is to equip you with all the code snippets, design principles, and development best practices you need to craft gorgeous, polished buttons guaranteed to drive conversions and interactions.
Buckled in? Let‘s get started!
Why Button Design Matters
More Than You Think
Before diving into code, I want to share some data that woke me up to how crucial button design factors into your website or app‘s success metrics:
- A study by HubSpot and UXPin found button color alone can boost click-through rates by over 30% [1]. Imagine what tailored borders could do!
- Google‘s research indicates page visits with more prominent call-to-action (CTA) buttons enjoy a 212% higher CTR compared to pages with inconspicuous CTAs [2].
- Users make decisions about a system‘s credibility within 50 milliseconds of viewing a web page [3]. Make sure your buttons signal trustworthiness.
Let‘s digest this. Buttons serve as microcosms for overall UX and visual design choices. Users subconsciously draw expansive judgements from small details like button appearance.
That‘s why I invest so heavily in honing button style and aesthetics. The data shows button design intricacies translate directly into hard business metrics like conversions, transactions, and growth.
Now that I‘ve hopefully convinced you of the immense value button coding finesse brings, let‘s get to the borders!
Bordering Buttons: Basic Properties and Values
The CSS property used to style borders is aptly named border and accepts a wide variety of values to specify border displays.
At minimum, border requires a width and style:
/* Format */
border: [width] [style]; Let‘s break this down:
Width
Defines border thickness with common size units like px, em, or percentages:
/* Examples */
border: 2px;
border: 0.3em;
border: 5%;Style
Specifies appearance such as solid, dashed, double, dotted, etc:
/* Examples */
border: 1px solid;
border: 3px dashed;
border: 4px double;We can condense width, style, and color into one property:
/* Format */
border: [width] [style] [color];For example:
border: 3px dotted purple;This single versatile property provides a world of button border flexibility!
Now that you know the basics, let‘s move on to some professional techniques and design principles for employing borders to augment button interfaces.
Ensure Adequate Contrast Between Button Borders and Background Colors
When choosing border hues, first and foremost ensure colors contrast sufficiently from underlying background colors.
- Insufficient contrast makes borders fade into backgrounds, rendering buttons invisible to users.
Referencing color theory contrast ratios, Google‘s Material Design system prescribes:
"Button borders with less than 3:1 contrast ratio with adjacent colors are difficult to see" [4].
For example, a light grey border blends precariously into a white background:
As compared to a high contrast dark border that boldly delineates the enclosed button shape:
To guarantee border visibility, use color picker tools to test ratios. Contrast should rate at least 4.5:1, with 7:1 being ideal.
Once confident with contrast, have fun harmonizing border hues to color schemes brand personalities. Just keep critical visibility thresholds in mind!
Now let‘s move on button border stylistic considerations.
Tailor Border Widths to Button Size
How thick should your pixel-perfect button borders be? Well, it depends!
- Follow the Goldilocks principle — set border widths relative to button dimensions. Too thin gets lost. Too thick overwhelms. Just right elegantly accentuates.
Material Design‘s metrics help guide appropriate sizing [4]:
| Button Area | Suggested Border Width |
|---|---|
| Smaller than 36px | 1px |
| 36px – 48px | 2px |
| Larger than 48px | 3px |
For example, these 24px square circular buttons pair 1px borders with their compact footprint:
While these large 96px buttons harmonize better visually with hearty 4px borders:
Dial in border widths relative to internal button proportions for optimal cohesion.
Now let‘s explore creative border style variations to make mundane buttons pop!
Explore Unique Border Styles Like Dashed, Double, Grooved and Ridge
Beyond conventional solid lines, borders offer a spectrum of unconventional styles for distinguishing generic buttons:
A fewwallet favorites:
Dashed: Airy punctuation
Double: Dimensional depth
Grooved: Textured intricacy
Ridge: Bold contour
Experiment mixing and matching border styles across button groups for design interest while maintaining visual cohesion:
Creatively working in novel borders makes buttons pop!
Up next, let‘s tackle rounding borders to perfect curves buttons beautifully.
Round Border Corners for Sugary Sweet Buttons
Square corners scream no-fun and dated. For contemporary charm, generously round borders with CSS‘s aptly named border-radius property.
At its simplest:
button {
border-radius: 10px;
}But border-radius offers more fine-grained control with additional value options:
/* Round individual corners */
border-radius: [top-left] [top-right] [bottom-right] [bottom-left]
/* Or shorthand */
border-radius: [top-left/bottom-right] [bottom-left/top-right]
/* Make elliptical */
border-radius: [horizontal] / [vertical] This flexibility permits crafting intricately shaped buttons like these snazzy speech bubbles:
And circular social media icons:
With all these options for nuance, no excuse for boring angles!
Now let‘s talk animating borders for dynamism.
Animate Button Border Width, Color and Shape For Snazzy User Feedback
Subtly changing border properties during user interactions grabs attention while conveying system state.
Here‘s a neat example using a thick border that fluidly morphs thinner on hover:
The CSS employs the transition property to smoothly animate a border width adjustment:
button {
border: 10px solid purple;
transition: border-width .3s ease-out;
}
button:hover {
border-width: 5px;
}Border colors also effortlessly shift via CSS transitions:
And for extra flash, dynamically reshape borders by toggling styles:
Subtle flair goes a long way to delighting users while keeping focus on compelling core content.
Okay, let‘s level up button borders with shadows and images!
Fancy Button Borders: Combine Borders with Shadows, Gradients and Images for Depth
Plain borders only go so far. For pro-level dimension, texture and effects: blend borders with shadows, gradients and images.
The CSS box-shadow property paints layered shadows inside and around borders:
button {
box-shadow: inset 0 0 0 5px rgba(0,0,0,0.5);
}While the linear-gradient() function generates gradient borders with hard stops and seamless color blending:
button {
border: 4px solid;
border-image: linear-gradient(to right, red, yellow);
}And for pushing creative limits, SVG images convert into astonishing borders:
Finessing borders with multimedia elements opens vast possibilities for button beauty!
Now that we‘ve built up an extensive stylistic toolkit, let‘s apply some best UX practices around employing borders for conversational buttons your users will love engaging.
Conversational Button Borders: UX Tips for Inviting Interaction
Thus equipped with an arsenal of technical border styling capabilities, what higher order design principles guide applying all these effects judiciously?
Let‘s take some wisdom from the user-centered design concept of conversational UI:
"Conversational UI involves crafting interfaces that deliver messaging to users conversationally — much like speaking face-to-face rather than lecturing at a podium" [5].
What does this have to do with borders you ask?
Well, conservatively dashing borders…
- Provide breathing room around buttons so groups don‘t visually bleed together into walls of indistinguishable shapes
- Help guide focus to key calls-to-action while lowering prominence of secondary options
- Communicate interactivity through chronological animations and microfeedback
- Overall humanize interfaces through nuanced stylistic flourishing
Take for example this checkout button sequence with various border treatments:
Rounded borders distinguish buttons while animated illumination guides through workflow.
These subtle but impactful border decisions conversationalize buttons to feel friendlier!
So in UX work, consider borders not superfluous decoration, but vital tools for infusing personality and directness into interactions.
Alright, we‘ve covered a ton of ground upskilling our border prowess. Let‘s recap key lessons before wrapping up!
