### Opaque text

Some browsers (such as Firefox) set the default {{cssxref("opacity")}} of placeholders to something less than 100%. If you want fully opaque placeholder text, set `opacity` to `1`.
Some browsers make placeholder text less opaque. If you want fully opaque text, then set the {{CSSXref("color")}} property value explicitly. The [`currentColor`](/en-US/docs/Web/CSS/color_value#currentcolor_keyword) value can be used to have the same color as the corresponding input element.

#### HTML

```html
<input placeholder="Default opacity" />
<input placeholder="Full opacity" class="force-opaque" />
<input placeholder="Color set by browser" />
<input placeholder="Same color as input" class="explicit-color" />

<input placeholder="Semi-opaque text color" class="opacity-change" />
```

#### CSS

```css
::placeholder {
input {
font-weight: bold;
color: green;
}

.force-opaque::placeholder {
opacity: 1;
.explicit-color::placeholder {
/* use the same color as input element to avoid the browser set default color */
color: currentColor;
}

.opacity-change::placeholder {
/* less opaque text */
color: color-mix(in srgb, currentColor 70%, transparent);
}
```

#### Result

{{EmbedLiveSample("Opaque_text", 200, 60)}}
{{EmbedLiveSample("default_color", 200, 60)}}

> [!NOTE]
> Note that browsers use different default colors for placeholder text. For example, Firefox uses the input element's color with 54% opacity, and Chrome uses `darkgray` color. If you want consistent placeholder text color across the browsers, then set the `color` explicitly.
