Request from my baby Mira, well okay here's for you, simple tuto. Tak tau lah kalau awak pakai Classic or design template. Tapi Joy sediakan dua-2 jerlah ;) Hmm just follow step by step, goodluck :D
For Classic Template :
All you have to do, you look for the sidebar id macam h1 ke apa ke, tak tau, is depend sometimes. Tapi ada kena mengena. Then you just have to insert this inside them, make sure you put the code before symbol } *Note that dear :)
The code :
background: url(PICTURE URL);
For Design Template :
Edit HTML > Tick Expand Widget Templates > Look for this code :
h2 {
Dah jumpa? Good, next step, cari code ni dekat bawah code h2 } tadi, text-transform:uppercase; dah jumpa? Kalau dah jumpa, letak jer code bawah ni dekat bawah text-transform:uppercase; tadi
background:url('PICTURE URL');
Example, dia akan nampak macam ni :)
h2{text-align:center;
margin: 0 0 1em 0;
font:$(font family);
color:$(text font color);
text-transform:uppercase;
background:url('PICTURE');
Make sure preview dulu baru save, anything, find me in Twitter kalau tak dapat juga :D
