CSS-防止元素包装在进度栏中

Question

I'm designing an animated progress bar to display ratings on my website. At the end of the bar, I want to display inside a circle the rating number (out of 10) corresponding to the final progress % of the bar. I want to have a responsive design.

My problem arises when dealing with a high progress %, such as 95%. The circle with the rating value is sent down to the next line. It is also the case when resizing my browser with a progress value such as 75%. With lower values, everything is fine. I tried to play around with negative margin-left and margin-right values for #ratingnumber , which seems to help a bit but still had trouble keeping the rating circle on the progress bar for really high progress %.

I'm looking for the CSS tweak to keep the rating circle on the progress bar for every rating cases.

Add white-space: nowrap to the parent element, #progressbar . Then remove float: left from the children elements, and change the display to inline-block in order for them to respect the white-space property on the parent. Set vertical-align: top on the children in order to fix the vertical alignment.

Updated Example

#progressbar {
    white-space: nowrap;
}
#ratingnumber, #progress {
    display: inline-block;
    vertical-align: top;
}

The positioning on the #ratingnumber element also needs to be changed to:

#ratingnumber {
    position: relative;
    top: -20px;
}
