Tips for creating a slightly darker background-color for an element with CSS

One of the challenges I am facing is changing the CSS for a button:

.Button {
  background-color: #somehex;
}

After experimenting with different methods, I have settled on adjusting the background-color to be slightly darker when the user hovers over the button:

.Button:hover {
  transition: 0.2s ease-in;
  background-color: #ALittleDarkerHex;
}

However, this process can be quite laborious as I have to manually find a darker shade of the existing color. Is there an easier way in CSS to darken the background-color of a button?

Answer №1

To enhance the appearance of your text, consider adding a dark layer on top of it using the background-image property. This technique maintains the text color while altering only the background.

.button {
  display: inline-block;
  color: #fff;
  padding: 10px 20px;
  font-size: 20px;
  background-color: red;
}

.button:hover {
  background-image: linear-gradient(rgb(0 0 0/40%) 0 0);
}

<div class="button"> some text </div>
<div class="button" style="background-color:lightblue;"> some text </div>
<div class="button" style="background-color:green;"> some text </div>
<div class="button" style="background-color:grey;"> some text </div>

If you want to add a transition effect:

.button {
  display: inline-block;
  color: #fff;
  padding: 10px 20px;
  font-size: 20px;
  background: linear-gradient(#0000, rgb(0 0 0/40%)) top/100% 800%;
  background-color: red;
  transition: 0.5s;
}

.button:hover {
  background-position: bottom;
}

<div class="button"> some text </div>
<div class="button" style="background-color:lightblue;"> some text </div>
<div class="button" style="background-color:green;"> some text </div>
<div class="button" style="background-color:grey;"> some text </div>

Another approach utilizing mix-blend-mode:

.button {
  display: inline-block;
  color: #fff;
  padding: 10px 20px;
  font-size: 20px;
  background-color: red;
  background-image: linear-gradient(rgb(0 0 0/40%) 0 0);
  background-blend-mode: lighten;
}

.button:hover {
  background-blend-mode: darken;
}

<div class="button"> some text </div>
<div class="button" style="background-color:lightblue;"> some text </div>
<div class="button" style="background-color:green;"> some text </div>
<div class="button" style="background-color:grey;"> some text </div>

You can also achieve a similar effect by adding a large inset box-shadow and include a transition for added flair:

.button {
  display: inline-block;
  color: #fff;
  padding: 10px 20px;
  font-size: 20px;
  background-color: red;
  box-shadow: 0 0 0 100vmax inset rgb(0 0 0/var(--o,0%));
  transition: .4s;
}

.button:hover {
  --o: 40%;
}

<div class="button"> some text </div>
<div class="button" style="background-color:lightblue;"> some text </div>
<div class="button" style="background-color:green;"> some text </div>
<div class="button" style="background-color:grey;"> some text </div>

Here is a suggestion on how it can be done

.btn {
  background-color: blue;
}

.btn:hover {
    filter: brightness(80%);
}

<button class="btn">Click Me</button>

Increasing the value above brightness(100%) will raise the brightness, while lowering it will darken the color.

For a more user-friendly option, you might want to consider utilizing HSL color values instead of the Hex color code (#FF0033). The HSL color model is easier for humans to read and comprehend.

HSL color values follow this format: hsl(hue, saturation, lightness).

div {
  width: auto;
  display: inline-flex;
  justify-content: center;
  align-items: center;
  margin: 0.5rem 0;
  padding: 1rem 2rem;
  color: white;
}

.Button {
  --hue: 348;
  --saturation: 100%;
  --lightness: 50%;
  background-color: hsl(var(--hue), var(--saturation), var(--lightness));
}

.Button.dark:hover {
  transition: 0.2s ease-in;
  --lightness: 40%;
  /* 20% dark */
}

.Button.light:hover {
  transition: 0.2s ease-in;
  --lightness: 80%;
  /* 20% light */
}

<div class='Button dark'>PayPay</div>
<div class='Button light'>PayPay</div>

Create a CSS animation that changes the background color of a button when clicked

const colors = ['#052F5F','#005377','#06A77D','#D5C67A','#F1A208'];
const btn = document.querySelector('.Button');
btn.addEventListener('click', (e) => {
  e.preventDefault();
  btn.style.backgroundColor = colors[Math.floor(Math.random() * colors.length)];
});

.Button {
  background-color: #F1A208;
  color:#fff;
  border: 0;
  border-radius: 20px;
  padding: 10px 22px;
  cursor:pointer;
  position: relative;
}
.Button:before {
  content: '';
  position: absolute;
  z-index:0;
  border-radius: 20px;
  top:0;
  left:0;
  right:0;
  bottom:0;
  background-color: rgba(0,0,0,0);
  transition: .2s ease;

One alternative method is to incorporate CSS's color-mix() function, which enjoys broad support from all leading web browsers: check here

:root {

  --col-primary    : blue;

}

body { background-color: #232324; }

button {

  --bg-color: var(--col-primary);

  color: white;
  padding: 2rem;
  background-color: var(--bg-color);
  border: 0;
  border-radius: 8px;
  transition: background-color 400ms;

}

button.darken:hover {

  --bg-color: color-mix(in hsl, var(--col-primary), black 20%);

}

button.lighten:hover {

  --bg-color: color-mix(in hsl, var(--col-primary), white 20%);

}

button.alpha:hover {

  --bg-color: color-mix(in hsl, var(--col-primary), transparent 95%);

}

<button class="darken">Darken</button>
<button class="lighten">Lighten</button>
<button class="alpha">Transparentize</button>

Answer №6

To achieve a smoother transition effect, consider using a slightly darker background color and incorporating it into the hover function along with transitions for added smoothness. Whether you opt for RGB or RGBA values for the background color is up to you.

<button class="button">button</button>

<style>
  .button {
    Border: none;
    Border-radius: 4px;
    Color: white;
    Cursor: pointer;
    Width: 86px;
    Height: 32x;
    Background-color: rgba(121, 82, 179);
    color:white
    transition:all 1s;
  }
  
  .button:hover {
    Background-color: rgba(114, 77, 170, 80);
  }
</style>
