this code will return wrong result
<script type="text/javascript"><!--$('.vtabs a').tabs();</script>
Ofc it will, it's not valid code. You have a HTML comment tag that shouldn't be there :)
CSS function strips spaces that are required in "calc" functions
Javascript function turns
string = string.replace(/\//g, '_').replace(/\+/g, '-');
into
string = string.replace(/\
How to solve this error in suiteCRM.when i try to create a target list it shows this error

Guys i need your assistance please
Hey guys, this removes spaces in css that are inside a calc() which leads to it becoming an invalid property value, does anyone know the fix?
Thanks <3
Hey guys, this removes spaces in css that are inside a
calc()which leads to it becoming an invalid property value, does anyone know the fix?
maybe is too late, but just FYI ive fixed it on a old project i made TriForceX/BootstrapExtended#14
Ran into a bug using this function with exceptionally large files (like 1 MB+ worth of HTML to minify). Specifically, above a certain string size, minify_html seems to return an empty string (or some other false-y value).
Added a "ghetto hack" as shown below. HTML will not be minified, but will at least return the original HTML.
$original_input = $input;
/* The rest of the function */
if (!$input)
return $original_input;
return $input;
One problem, it removes whitespace in CSS calc() for example
font-size: calc(36px + (80 - 36) * (100vw - 320px) / (1366 - 320));
Becomes:
font-size: calc(36px+(80-36) * (100vw-320px) / (1366-320));
Which is invalid.
Fixed problem in whitespace in CSS calc()
thanks @jcmarchi and @TriForceX for solution
css replace 0% It will cause crash keyframes uses ( 0% ) ...
css replace 0% It will cause crash keyframes uses ( 0% ) ...
Hi Rodrigo, any lucky looking into this one? keyframes are increasingly getting more important in nowadays CSS implementations and it can surely start being a problem in many cases.
css replace 0% It will cause crash keyframes uses ( 0% ) ...
Though I don't do css much, I think \d% in keyframe rules is always followed by {. Hence this pattern would work: (?<=[\s:])(0)(cm|em|ex|in|mm|pc|pt|px|vh|vw|%)(?!\s*\{).
One problem,
var loadPage = function(){
// Content
}
var loadPage = function(){
// Content
}
When compressing an error.
Here is correct.
var loadPage = function(){
// Content
};
var loadPage = function(){
// Content
};
How to fix this.
Thank!
These are great, thanks! Like others, I removed the 0 replacement line. Thanks for much for sharing.
Thank you so much
could you guys explain me about Keep important white-space(s) after self-closing HTML tag(s) '#<(img|input)(>| .*?>)#s', and '#<(img|input)(>| .*?>)<\/\1>#s'
an example would be great 😄
It's a great fork that saved me for original one caused a weird bug for code:
