What is the HEX code for Transparent color

Answer 1

There is no such thing; transparency is done via another channel.

Answer 2

It depends on the format, some systems require RRGGBB, which doesn't include alpha.

Some have their format as AARRGGBB, so your provided color would be 05FF00FF.

Conversely, some have their format as RRGGBBAA, thus your provided color would be FF00FF05.

Answer 3

You can use rgba(255,0,255,1)

 <svg class="svg_element" style="margin-top:0px;margin-left:560px">
        <circle cx="25" cy="25" r="20" fill="rgba(128, 0, 128, 0.75)" 
            stroke="rgba(0, 255, 0, 0.25)" stroke-width="10"/>
        <circle cx="75" cy="25" r="20"
            fill="rgba(0, 255, 0, 1)"
            stroke="rgba(0, 0, 255, 0.1)" stroke-width="10"/>
        <circle cx="125" cy="25" r="20"
            fill="rgba(255, 255, 0, 0.75)"
            stroke="rgba(255, 0, 0, 0.25)" stroke-width="10"/>
 </svg>
