HTML 左浮動(dòng)
Sep 04, 2024 pm 04:50 PM
Alignment of the elements for building the HTML webpage is one of the most important tasks. This can be done by using one of the CSS property called float with its position value. Float property can be used with values as Right, Left, none, inline-start, inline-end. Float Left tag in HTML is responsible to show all text or elements into the left side of the included container or in the left position body part of HTML. Whenever this float left element is used its changes the normal flow of contents and moves, it’s towards the left side of the container.
Syntax
- The syntax for defining position float left in HTML is as follows:
float:position_value;
- As shown in the above syntax, floated elements are going to show with their position value. It could be left, right or none. Ex: float: left;
- Some situation comes where we want to change the position of elements below floated elements. So we want to clear elements before putting any other elements by clearing floats.
- Floating elements help us move contents into the same parent who will be going to move on and wrap all those elements around the floating elements.
- One of the alternative options for Float based layouts is Flexbox, which is used for designing modern websites layout.
- While designing any webpage, we are going to use header, navigation menu, sidebar, navbar, main content of the page, and footer. All those are treated as a container element that is stored as HTML content.
- One can use more than one left floated element in their webpage. So it will be useful for designing the multi-column layout.
- The best website design is considered the use of 3 nested div blocks, which helps design the layout of the page, including a container block, along with a full-width page for storing all elements and one more block called sidebar content blocks. Those two blocks are aligned with HTML property float left.
- Float left property can be useful in both inline as well as block-level elements. It’s also useful for displaying an image on the left side of the div.
- Float elements can be applied only on elements that are placed horizontally in the code structure.
