Is there a way to properly display data containing Unicode full block characters (\u2588) without gaps caused by font smoothing in browsers? ██████████████
What methods can be used to render these characters seamlessly?
I experimented with using CSS 'line-spacing' set to a negative value, but found that this distorted the alignment of the mono-space typeface text and disrupted the overall content layout.
I've been facing the same issue for quite some time now, constantly seeking out a flawless solution. While Kieran Devlin's CSS text-shadow method works well, it is primarily effective for single-line blocks with identical colors.
One alternative approach that I can recommend involves utilizing JavaScript (or simply CSS), although it may not be entirely foolproof. This method ensures that the user is using Chromium and then merges the blocks together to fill any gaps. Subsequently, we can use transform scale to revert back to the initial size, and transform translateX to return it to its original position.
if (window.chrome) {
art_div.css({
'letter-spacing': '-0.1em',
'line-height': '1.2em',
'transform': 'scale(1.2, 1) translateX(8%)'
});
}
You can visualize this process in my GitHub issue. Perhaps I will discover an even better solution along the way.
One way to fill the gap is by using font shadow. Although it may be considered a hack, it can be effective unless you are planning to overlap the characters in a fixed orientation, which may not work consistently across different browsers.
text-shadow: 1px 0px 0px rgba(0,0,0,1);
For example:
body {
text-shadow: 1px 0px 0px rgba(0,0,0,1);
} ██████████████Another approach is to pad the characters within a container and set the background color to match the font color. For instance:
#container {
background: black;
color: black;
width: 159px;
height: 20px;
} <div id="container">
