How to render a progress element from right to left? - css

Question

I have a progress bar that show from left to right. I need to make another which is same style progress but will show from right to left.
Here is my style definition:
progress, progress[role] {
-webkit-appearance: none;
appearance: none;
border: none;
background-size: auto;
height: 50px;
width: 100%;
padding-top: 10px;
}
progress[value]::-webkit-progress-bar {
background-color: grey;
border-radius: 2px;
box-shadow: 0 2px 5px rgba(0, 0, 0, 0.25) inset;
}
progress[value]::-webkit-progress-value {
background-image:
-webkit-linear-gradient(-45deg,
transparent 33%, rgba(0, 0, 0, .1) 33%,
rgba(0,0, 0, .1) 66%, transparent 66%),
-webkit-linear-gradient(top,
rgba(255, 255, 255, .25),
rgba(0, 0, 0, .25)),
-webkit-linear-gradient(left, #09c, #f44);
border-radius: 2px;
background-size: 35px 20px, 100% 100%, 100% 100%;
}
.valuebar {
position: relative;
}
.valuebar h3 {
color: #fff;
left: 1em;
line-height: 1;
position: absolute;
}
I used sample from the web which uses ::-webkit-progress-value.
How can I make it render from right to left?

Answer 1

Generally, many elements flip their horizontal rendering when their direction attribute is changed from ltr (which is the default) to rtl, which stands for right-to-left (to be compatible with right-to-left languages, such as Arabic or Hebrew).
The <progress> element is not different. Just give CSS something to cling to (such as a special class) and set its direction: rtl;.
Here is a small snippet based on the code you posted.
/* this is the important bit */
progress.rtl {
direction: rtl;
}
progress,
progress[role] {
-webkit-appearance: none;
appearance: none;
border: none;
background-size: auto;
height: 50px;
width: 100%;
padding-top: 10px;
}
progress[value]::-webkit-progress-bar {
background-color: grey;
border-radius: 2px;
box-shadow: 0 2px 5px rgba(0, 0, 0, 0.25) inset;
}
progress[value]::-webkit-progress-value {
background-image: -webkit-linear-gradient(-45deg, transparent 33%, rgba(0, 0, 0, .1) 33%, rgba(0, 0, 0, .1) 66%, transparent 66%), -webkit-linear-gradient(top, rgba(255, 255, 255, .25), rgba(0, 0, 0, .25)), -webkit-linear-gradient(left, #09c, #f44);
border-radius: 2px;
background-size: 35px 20px, 100% 100%, 100% 100%;
}
.valuebar {
position: relative;
}
.valuebar h3 {
color: #fff;
left: 1em;
line-height: 1;
position: absolute;
}
<progress value="59" max="100">59%</progress>
<br />
<progress class="rtl" value="59" max="100">59%</progress>
I don't know what is your markup, as you did not post it, but you may need to adjust the .valuebar positioning.
Here is a code pen you can toy with.
