By default, the blocks defined by the tag occupy a column on the page and align to the right. To change this default behavior, simply define the float style attribute.

Tag Positioning Style Setting Tips

Tags are widely used in settings related to web page layout, and several important properties of CSS provide support for this, such as float, overflow, or text-align. Proper design and application of style attributes allow us to efficiently complete the work of web page layout.

By default, the blocks defined by the tag occupy a column on the page and align to the right. To change this default behavior, simply define the float style attribute. Its main function is to define the floating position of objects on the web page. There are two possible attribute values: left and right, specifying left or right alignment. After specifying the label of this attribute, it will be automatically configured in the same line and closer to the left or right. Take the following label setting as an example:

The first tag does not specify float, so it occupies the space of the top single column of the page, and the second and third tags are arranged immediately below, to the left and right. The result page is as follows:

In addition to specifying float properties, we can also achieve label effects by configuring nested labels. For example, for a table with 3 rows by 3 columns, the required labels are as follows:

This tag yields the following page results:

The float attribute determines the location of the block on the page, and if you want to define the location of the block's content elements, you must use another attribute named text-align. The most important attribute values are left, right and center, which can be used to make the content left, right or center. Take the following label design as an example. Three labels have different text-align attribute values set.

Using CSS styles with tags allows us to achieve the layout of the page we want to present. Once you understand these techniques, the next step is to design a web page layout according to your own needs. Before concluding this section, one more thing to remind readers is that CSS, in addition to effectively separating style design from web content and allowing HTML tags to focus on content presentation, is most importantly able to speed up web page loading. When a user browses a web page, the associated CSS style file is loaded only once and stored in the cache, and when the next request is sent to the server, the required CSS style file is retrieved directly from the cache. Pages that do not use style files must reload the entire page, and you can imagine the performance difference between the two, which is one of the reasons why it is not recommended to use tags for layout design.
