This post is here just to help anyone who struggles without visible text edit function. There are a few easy codes you can use to change text within your posts.
Code for italic font:
<i> your text here </i>
For bold font:
<b> your text here </b>
<center> your text here </center>
<u> your text here </u>Strikethrough text:
<strike> your text here </strike>
<h1> your text here </h1>
For thematic breaks:
<hr>your text here
This is an example!
As for spoilers, type [ spoiler ] [ /spoiler ] without spaces with your content inside it.
As for titled spoilers, type [ spoiler=Title ] [ /spoiler ] without spaces with your content inside it.
Note: do not add any exclamation points or any other symbols to the title, it will break the whole thread. Having too many spoilers within the same post might also break the thread.
Use this code if you wish to change your font size :
<font size="number"> your text here </size>
Code for images:
<img src="Insert image address/url here">
Important note: Please try to keep as less coding as possible within your threads as they tend to break when there's too much coding within a single post and refuse to format properly due to one coding overriding the other one.
