This document discusses CSS layout properties including display, box model, positioning, floats, and tables. It covers: - Common display property values like block, inline, and inline-block and how they affect layout. - The box model including content-box, padding-box, border-box, and how they treat width and height. - Float positioning and how it removes elements from the normal flow, plus clearfix techniques. - Positioning values like static, relative, absolute, and fixed and how they position elements. - Other properties like overflow, z-index, and negative z-index that control layout stacking. - Using CSS to structure tables and basic table layout

- 1. CSS Layout
- 2. Display property Block Inline Inline-Block Combined style like inline element, but we can set width, height. Others (list-item, table,inline-table,table-row,table-cell, none)
- 3. Display property block Has width( or take all parent width), height (or stretch by content), always start at new line. Inline Go one by one, width always stretch by content, height = line- height property
- 4. Display property Inline-block Has width(or stretch by content), height (or height = line-height property), go one by one.
- 5. BOX Model
- 6. Box-sizing content-box (Default value) width, height for content only. Padding-box Width, height including padding Border-box Width, height including padding and border
- 7. Margin margin: 20px; margin: 5px 10px 15px 20px; margin: 5px 10px 15px; margin: 10px auto; Collapsing vertical margin
- 8. Relative Margins / Paddings .parent { border: 1px solid red; width: 300px; } .child { margin:20%; border: 1px solid green; } All margins will be 60px = 20% from parents width
- 9. Float http://jsfiddle.net/ywRW6/5/ <div class="block"> Hello CODE! <div class="float"> float element </div> Can you see this? It's floated! </div> .float { float: left; background: #CCC; width: 200px; height: 200px; margin-right: 25px; padding: 10px; } img {float: right;}
- 10. Float .clearfix {clear: both;} .clearfix { overflow: auto; }
- 11. Position static (default) relative .box2 { position: relative; top: -5px; left: 10px; } fixed .fixed { position: fixed; bottom: 0; right: 0; width: 200px; }
- 12. Position Absolute .relative { position: relative; width: 600px; height: 400px; } .absolute { position: absolute; top: 120px; right: 0; width: 300px; height: 200px; }
- 13. Overflow visible hidden scroll auto text-overflow: ellipsis;
- 14. Z-index <div class="block one"> Parent 5 <div class="block two"> Child 500 </div> </div> <div class="block three"> Absolute 10 </div> Stacking Context: 1)position != static ; z-index != auto 2)opacity <1 3)transform or perspective (CSS3)
- 15. Negative Z-index .parent { position: relative; } .child { position: absolute; z-index: -1; }
- 16. Table table { display: table } caption { display: table-caption } thead { display: table-header-group } tbody { display: table-row-group } tfoot { display: table-footer-group } tr { display: table-row } td, th { display: table-cell } <style> .header {height:60px; background-color:#717dc9; padding:20px; text-align:center} .left_col {width:120px; height:460px; background-color:#dddddd; padding:15px; vertical-align:top} .center_col {background-color:#ffffff; padding:15px; vertical-align:top} .right_col {width:120px; background-color:#dddddd; padding:15px; vertical-align:top} .footer {padding:10px 0 10px 20px; background-color:#717dc9; font-size:13px} </style> <table cellpadding="0" cellspacing="0" width="100%" align="center"> <tr><td colspan="3" class="header">My site</td></tr> <tr><td class="left_col">Left Menu</td><td class="center_col">Content streched to screen width</td> <td class="right_col">Right block</td></tr> <tr><td colspan="3" class="footer">© All rights reserved</td></tr> </table>
