The behavior remains consistent, but the use of transparent is also compatible with IE8 as stated in this source. On the other hand, RGBA offers more advanced features (with no support for IE8, according to this reference) and allows for quick modifications to achieve an "almost transparent" color without completely altering the attribute.
For instance, setting a background-color like this could be done swiftly:
background-color: rgba(0,0,0,0.1);
It's possible to combine both properties to cater to different browsers; using one for newer ones and a fallback for older ones by including them both:
background-color: transparent;
background-color: rgba(0,0,0,0);
Alternatively, for achieving an "almost transparent" effect on backgrounds that are already referenced, you can write:
background-color: transparent;
background-color: rgba(0,0,0,0.1);
In such cases, new browsers will prioritize rgba(0,0,0,0.1) over the previous transparent declaration while IE8 will default to transparent due to its inability to recognize the value of rgba(). This results in a slightly varied outcome but aligns with the principle of Graceful Degradation.
It should be noted that using
background_color: rgba(0,0,0,0.0);background_color: transparent;.
The use of background_color is common in both indicators without issue. The real question lies in choosing between transparent and rgba.
Transparent creates a background with no color option, while other options like hex or accepted color values can be specified, such as
blue rgb(x,x,x) rgba(x,x,x,x) #xxxxxx hsl(x,x,x) hsla(x,x,x,x)rgba(x,x,x,x) is a bit complex and needs clarification. This method involves specifying a color and transparency level. The "rgb" part represents red, green, blue with values ranging from 0 to 255, which when combined produce a color.
The "a" in (rgba) stands for ALPHA channel, determining opacity/transparency, with values from 0.0 to 1.0. A value of 0.0 is fully transparent, while 1.0 is solid. For example, rgba(x,x,x,0.5) would result in a color at 50% transparency.
There's a specific situation where you'll notice a distinction between the two.
I encountered a scenario in which I needed to add a red diagonal line as a strikethrough within a div with a transparent background, not rgba(0, 0, 0, 0).
Here is the snippet of my code:
<div className="relative">
<p>Text goes here</p>
<div style={{background: "linear-gradient(to left top, transparent 45%, #d10813 48.5%, #d10813 51.5%, transparent 55%)"}} className="absolute top-0 w-full h-full"></div>
</div>
If you replace transparent 45% with rgba(0, 0, 0, 0.45), you will notice that it no longer functions correctly.
In essence, using transparent with opacity is not the same as using black with opacity, as evident.
