Attempting to determine if the head section in jQuery contains the font-weight:bold property within CSS. That particular property may exist in 4 different variations:
font-weight:boldfont-weight: boldfont-weight :boldfont-weight : boldIs there a way to use regex to match all of these variations?
Give this a try
\b(?:font-weight\s*:[^;\{\}]*?\bbold)\b
If you prefer, you could use:
\b(?:font-weight[\s*\\]*:[\s*\\]*?\bbold\b)
Here's the breakdown
\b # Make sure we're at a word boundary
(?: # Start of non-capturing group
font-weight # Match "font-weight"
[\s*\\] # Match any white space or *
* # Zero or more times, greedy
: # Match ":"
[\s*\\] # Match any white space or *
*? # Zero or more times, lazy
\b # Make sure we're at a word boundary
bold # Match "bold"
\b # Make sure we're at a word boundary
)
I hope you find this explanation helpful.
It's important to keep in mind that specifying the CSS property font-weight:bold; can also be achieved by setting it as an integer value of 700 or utilizing a shorthand notation within the font property, which offers a broader range of options.
\b(?:font.*?:[^;]*?\b(bold|700))\b
Check out this Fiddle link for reference.
Here is a suggestion:
/font-weight: bold|font-weight:bold|font-weight :bold|font-weight : bold/
Give this a shot:
The code snippet to use is: RegularExpressionValidator.ValidationExpression = "font-weight\s?:\s?bold"
Regular expressions won't cut it in this case. CSS can include strings as shown below
.bar{ content: "text-decoration:underline;" }
To handle this correctly, you'll need a proper parser. Fortunately, modern browsers come equipped with one and provide APIs to access individual CSS rules.
