How can I adjust the opacity in Bootstrap 4? I have tried targeting the background elements like tooltip-inner and tooltip, but adding opacity:1 did not produce the desired effect:
.tooltip .tooltip-inner {
background-color: #014379;
}
.tooltip .arrow:before {
border-top-color: #014379;
}
What steps should I take to change the opacity successfully? Thank you!
To adjust the transparency of a tooltip, you can use the following CSS:
.tooltip.show {
opacity: 0.5;
}
If you've experimented with the following code snippet:
.tooltip.show /* Describing the CSS classes assigned to the tooltip */ {
opacity: 0.5; /* Customizable value */
}
Consider including !important to ensure your styling takes precedence:
opacity: 0.5 !important;
If the desired outcome is still not achieved, don't hesitate to reach out for further assistance.
Opacity ranges from 0 to 1, with 1 indicating no change and 0 representing invisibility.
.tooltip .tooltip-inner {
background-color: #014379;
opacity: 0.5;
}
.tooltip .arrow:before {
border-top-color: #014379;

</html>To adjust the transparency of the background color, you can utilize the rgba() function. However, this method does not support HEX colors unless you implement SCSS. In order to achieve this effect, you will need to select a color similar to #014379 but in rgb()
Here is an example using RGBA:
/*Instead of
background-color: #014379;
*/
background-color:rgba(XXX,XXX,XXX,0.5)
Example with SCSS:
Define SCSS Variable:
$color-tertiary: #607D8B;
Adjust Opacity:
background-color: rgba($color-tertiary, 0.5);
