Centering an inline block containing several inline elements. The block is centered horizontally - [ Open demo page ].

Sometimes there is a need to have a centered group of floated elements, which is to serve as a title or a pagination box. Since this group of floated elements is going to be used as a title for content blocks of various dimensions or pagination box may grow or shrink in its size, then the width of the group of floated elements is to vary unpredictably as well. So a method of centering based on using a certain known width of the box is not going to work.

And as an extra to the task there is a desirable condition: the title or pagination box has to be centered once and for all at the time of the box creation, so that this group of floated elements may be reused without any extra work over it: just place the complex where you need it and put the text or / and images you want to inside it - the group is centered anyway.

This problem can be solved by several methods using several technologies: CSS, CSS + JavaScript, CSS + HTML (<table></table> tags system). The CSS centering floated elements is the most simple and reliable. So, here a pure CSS centering of floated elements is discussed.

CSS rollover. Changing background image position

 

CSS rollover. Changing background image position. Example: CSS rollover. Changing background image position HTML / XHTML. Code: <div class="example"> <a href="css-rollover-changing-background-image-position.htm">CSS rollover. Changing background image position</a> </div> CSS. Code: .example {position: relative; top: 0px; left: 0px; height: auto; width: 100%; white-space: nowrap; padding: 10px 20px 10px 20px;} .example a {height: 35px; width: 100%; font-size: 24px; line-height: 35px; color: #006; text-decoration: none; text-align: right; display: block; background: url("bgimg.png") no-repeat left top;} .example a:hover {color: #c00; background: url("bgimg.png") no-repeat left bottom;} Background image: CSS rollover Changing background image position The concept : 1. A link with width and height declared explicitly (here it is 100% and 35px), plus display: block - this makes a 100% by 35px rectangle, the whole area of which is a hyperlink. Line-height is declared explicitly as well, equal to the rectangle's height (35px here) - it helps to have the same vertical alignment of the link text across various web browsers. Text-align: right is added to move the link text to the right in the the link block. (The link block area is highlighted in green to make it more obvious) CSS rollover. Changing background image position 2. An image for the link block area background with height equal to two heights of the link block area is created. The image has two parts, the upper one and the lower one, each of height equal to the height of the link block area; here it is 35px. 3. The background image URL is added to the background CSS property of the link. The CSS background property values of no-repeat and left position the background image to the left of the link block area. The CSS background property value of top places the upper part of the background image on the same level as the link text. 4. The background image URL is added to background CSS property of the link's :hover pseudo-class. The CSS background property values of no-repeat and left of the link's :hover pseudo-class position the background image to the left of the link block area. The CSS background property value of bottom of the link's :hover pseudo-class places the lower part of the background image on the same level as the link text, when a user moves the mouse pointer over the link block area. So, when there is no mouse pointer over the link block area, the upper part of the background image is placed on the same level as the link text. When there is a mouse pointer moved over the link block area, the lower part of the background image gets on the same level as the link text. Mouse out - the upper part is displayed, mouse over - the lower part shows up. And no need to preload any additional images. CSS rollover.
