Mobile browsers are not displaying placeholder transparency in CSS as expected

I'm trying to create input fields with fully opaque placeholder text

<input type="text" placeholder="Enter your name here"  />

Even though I've applied CSS properties to fix the transparency in Firefox, the text still appears translucent on iPhone and Android browsers

This is the CSS I have been using:

::-webkit-input-placeholder { /* WebKit browsers */
opacity:  0.8;
-webkit-opacity:0.8;
 -khtml-opacity: 0.8;
}

::-moz-placeholder { /* Mozilla Firefox 19+ */
  opacity:  0.8;
}
:-ms-input-placeholder { /* Internet Explorer 10+ */
  opacity:  0.8;
}

Does anyone know how to make the placeholder text completely opaque for Android and iPhone browsers?

Answer №1

To have control over how your content appears on different devices, you can make use of "media queries".

A media query is a tool that allows you to specify unique style rules based on the type of device or screen size.

For instance, if you want to customize the display for an iPhone6, you can use code like this to adjust transparency or apply specific CSS rules:

@media only screen 
and (min-device-width: 375px) 
and (max-device-width: 667px) { /* your styles here */}

Update

You can utilize the "!important" declaration to give certain rules higher priority. Take a look at the example below:

::-webkit-input-placeholder { /* For WebKit browsers */
     opacity: 1 !important;
}

Answer №2

To address the issue of transparency, I implemented RGBA in my code.

Using opacity alone was not effective for the entire element, so I switched to RGBA.

color:rgba(0,0,0,1);

::-webkit-input-placeholder { /* WebKit browsers */
opacity:  0.8;
-webkit-opacity:0.8;
 -khtml-opacity: 0.8;
 color:rgba(0,0,0,0.8);

}

::-moz-placeholder { /* Mozilla Firefox 19+ */
  opacity:  0.8;
  color:rgba(0,0,0,0.8);
}
:-ms-input-placeholder { /* Internet Explorer 10+ */
  opacity:  0.8;  
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=80)";
  color:rgba(0,0,0,0.8);

}
