the Font size not work in Entry #515

This is a ttk quirk rather than a ttkbootstrap bug: ttk::entry doesn't read its font from the style. style.configure('info.TEntry', font=('Helvetica', 24)) is accepted and stored (you can see it via ttk::style lookup info.TEntry -font), but the entry never renders it — so the text stays small. Unlike TLabel/TButton, the editable text widgets (TEntry, TCombobox, TSpinbox) carry -font as a widget option that defaults to the named font TkTextFont, and the widget always uses that instead of the style.

Two ways to actually change it:

1. Set the font as a widget option (simplest — per widget):

self.entry = ttk.Entry(bootstyle='info', font=('Helvetica', 24))
# or after creation:
self.entry.configure(font=('Helvetica', 24))

2. Reconfigure a named font (one handle for many entries, updates live):

from tkinter import font

# Option A: change the default font every text widget already uses
font.nametofont('TkTextFont').configure(size=24)

# Option B: define your own named font and attach it to the entry
my_font = font.Font(name='EntryFont', family='Helvetica', size=24)
self.entry = ttk.Entry(bootstyle='info', font='EntryFont')
# later, restyle every entry using it at once:
my_font.configure(size=18)

Because the entry holds a reference to the named font, mutating the font object reflows every widget using it — no need to touch each entry.

The gotcha to avoid: self.style.configure('info.TEntry', font=...) looks correct but is a no-op for the entry's rendered text. (If you saw it "work" alongside a TkTextFont.configure(...) call, the named-font change was doing the work, not the style.) Use the widget option or a named font instead.
