Ok - so this may be mentioned earlier but i still felt like sharing it out loud here
1 - many a times you wish that the texts or images etc - that you post in sidebars , mainly in text widget - should align at the center of sidebar - to do so you can use the div tag before your code -
<div align="center"> your text etc </div>
You can also replace center by - right !
2 - You may have noticed that many times - if you type too many spaces/linebreaks together, wordpress skips them to a single space/linebreak. To preserve the format of your text as such you can use the pre tag , Text in a pre element is displayed in a fixed-width font, and it preserves both spaces and line breaks -
<pre> wow this is so cool </pre>
hope it helps anyone, good day !
