Can you explain to me what a fallback color means? I searched online and found out that it is used to display a color when the specified format is not supported by browsers, like Internet Explorer. Is there anything else I should know about fallback colors?
I'm still not entirely clear on the concept of fallback colors, so could you provide an example for better understanding?
Appreciate your help!
Correct, a fallback color in CSS is a property or value that a browser will default to when it doesn't understand another property. The order of CSS rules matters because styles are read from top to bottom. It is important for the fallback color to be specified before the desired color. Here's an example:
div {
background: rgb(135, 206, 250); /* Fallback */
background: rgba(135, 206, 250, 0.7);
}
If a browser like IE8, which doesn't support rgba (red, green, blue with transparency), encounters the rgba line, it will ignore it and use the last valid value, in this case rgb. Modern browsers will apply rgb first and then update it with rgba from the next line.
