CSS (Weebly) blog sidebar, content width, scrollbars - Help, please!

Hi, everyone! I am new here and new to CSS!

cutomized checkboxs

well i recently learnt to customize checkboxes .

hers what i did : http://jsfiddle.net/d253kwox/

i have a few questions though .

glance through the code , you will see that the original checkboxes are hidden using the following code :

[type="checkbox"]:not(:checked),  
[type="checkbox"]:checked{
  position: absolute;
  left: -9999px;
}

is that a good thing to do ?

2nd question . notice that if you go to the following line of css code :

[type="checkbox"]:not(:checked) + label:before,

What does this trick do , what is the author of this code try to convey to us ?

q:before,q:after {
content:'';
}

Wordpress Kingsize Theme Transparent Content Box Question

Hi all.

Complete CSS amateur [who knows enough to follow a tut or too]

Site at eluminated.com.au

Want to make static home page; set a full width background image for this page only and then make the black content box transparent so the text appears to be sitting on top of the image.

I know I can do this with the body_class and some CSS however it is a lot beyond my skills.

Would appreciate some assistance to styling this one page with CSS as all googling reveals this would be the easiest way

Thanks in advance

tumblr theme: alternate positioning of content and sidebar

Hello,

I'm using tumblr and develope my own themes. I'll now try to optimize my current theme, remove unnecessary stuff and so on.

My question: Is there an alternate way to position two containers next to each other?

I'm currently using a fixed width on my content/sidebar and float left or right to position these elements within a container. Therefor I need an extra container around them where I can apply the clearfix-class to clear my content/sidebar. I want to remove this useless container and now I'm looking for a method not to float the two containers.
