Can I change the checkbox size using CSS?
...xt size
You can control the aspect, the color, the size of the checkbox
No extra HTML needed !
Only 3 lines of CSS needed (the last one is just to give you ideas)
Edit:
As pointed out in the comment, the checkbox won't be accessible by key navigation. You should probably add tabindex=0 as a proper...
Add text to Existing PDF using Python
...eate a new pdf containing your text to add using ReportLab, save this as a string object
read the string object using PdfFileReader(), we'll call this text
create a new PDF object using PdfFileWriter(), we'll call this output

How do I match any character across multiple lines in a regular expression?
... base R default engine with no perl=TRUE, for base R with perl=TRUE or for stringr/stringi patterns, use the (?s) inline modifier) (demo) also treat . the same way.
However, most POSIX based tools process input line by line. Hence, . does not match the line breaks just because they are not in sco...

What's the shortest code to cause a stack overflow? [closed]
...LL (relative call) is smaller still (not global memory, so no need for the extra 2 bytes):
RCALL $
1101 1000 0000 0000
So the smallest on the PIC18 is a single instruction, 16 bits (two bytes). This would take 2 instruction cycles per loop. At 4 clock cycles per instruction cycle you've got 8 c...
