I need help styling the subtitles

[cns00]

I am styling the subtitles by using Aegisub. This is what the subtitle file has:
{\pos(309,559.5)\fnCardo\fs50\b1\blur0.825\c&HEFEF F6&}Current\hPublicly\hAvailable\hInformation
{\an4\fnCardo\fsp-0.75\fs42\blur0.8\pos(87,634.5)\c&HF8F8F8&\b0}Abou t the Walls Part
{\fnMS PMincho\blur0.8\fs30\pos(364.5,634.5)\c&HF8F8F8&\b 1}\h①
{\an4\fnCardo\fs42\blur7.5\fsp-0.75\bord1.5\pos(87,673.5)\c&H090909&\3c&H090909&\ alpha&HFF&\b0}Humanity lives surrounded by {\alpha&H00&}three walls.
{\an4\fnCardo\fs42\fsp-0.75\blur0.8\pos(87,673.5)\c&HF8F8F8&\b0}Humanity lives surrounded by three walls.
{\an4\fnCardo\fsp-0.75\fs42\blur0.8\pos(87,757.5)\c&HF8F8F8&\b0}The outermost wall is Wall Maria,\Nthe second is Wall Rose and the\Nand the centermost wall is Wall Sina.

I want to modify the style. Is there anyone here who knows how to use the style coding in Aegisub?

What do you want to change exactly? What's the output you want?

Try using the styles manager, this avoids manually typing tags for every line.
Go to Subtitle > Styles Manager to create or modify styles. Use the video preview window to see how your changes look in real time. If you want to apply the same style to multiple lines, copy the tags and paste them into other lines.

However, here are the tags in your example and how you can modify them to change the style:

\pos(x,y): Positions the text at specific coordinates (x, y). Adjust the \pos(x,y) values to move the text to a different location.

\fn<font>: Sets the font (e.g., \fnCardo). U can replace \fnCardo with another font name, e.g., \fnArial

\fs<size>: Sets the font size (e.g., \fs50). Adjust the \fs value, e.g., \fs50 to \fs60 for a larger font.

\b<weight>: Sets bold (1 = on, 0 = off). Set \b1 for bold or \b0 for normal weight.

\blur<amount>: Adds a blur effect to the text. Change the \blur value, e.g., \blur0.8 to \blur2 for a stronger blur effect.

\c&H<color>&: Sets the primary text color (in hexadecimal, e.g., \c&HEFEFEF&). Modify the \c&H<color>& tag. For example, change \c&HEFEFEF& to \c&HFF0000& for red text.

\3c&H<color>&: Sets the outline color. Modify the \3c&H<color>& tag, e.g., \3c&H000000& for a black outline.

\alpha&H<value>&: Sets the transparency (FF = fully opaque, 00 = fully transparent).

\an<alignment>: Sets the text alignment (e.g., \an4 = bottom-center alignment). Use \an to change alignment. For example, \an7 aligns text to the top-left corner.

\fsp<value>: Adjusts the spacing between characters.

\bord<value>: Sets the border thickness.
