html parsing not support Fixed positioning

Analysis of the reasons why fixed positioning cannot be used in HTML

HTML is a markup language used to build web pages. It provides a rich set of tags and attributes that can achieve various web page layout effects. Among them, fixed positioning is a commonly used layout method, which allows elements to be displayed at a fixed position relative to the browser window or parent element, and is not affected by scrolling. However, not all HTML elements support fixed positioning. This article will analyze the reasons why fixed positioning is not supported in HTML and provide specific code examples.

First, we need to understand the syntax of fixed positioning. In HTML, CSS styles are used to control fixed positioning. We can change the positioning of elements through the position attribute in CSS. The fixed positioning method is to use position: fixed;, which can fix the element to a certain position on the screen or the parent element.

However, not all HTML elements support fixed positioning. According to W3C standards, the following elements do not support fixed positioning:

Inline elements: Inline elements do not support fixed positioning. Inline elements include , , , etc. Their characteristic is that they do not occupy a row by default, but are displayed together with other elements in a row. Because fixed positioning removes the element from the normal document flow, inline elements cannot achieve the effect of fixed positioning.

The sample code is as follows:

<span style="position: fixed; top: 20px; left: 20px;">This is a fixed inline element!</span>

Copy after login

Table element: Table element does not support fixed positioning. Table elements include , ,

, etc. Fixing some elements of the table will destroy the structure of the table and lead to disordered layout.

The sample code is as follows:

<table>
    <tr>
        <td style="position: fixed; top: 20px; left: 20px;">This is a fixed table cell!</td>
    </tr>
</table>

Copy after login

Form element (form element): The form element does not support fixed positioning. Form elements include , , etc., which are usually used to collect user input information, and fixed positioning may destroy the user's interaction with the form elements. </li></ol><p>The sample code is as follows: </p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><form style="position: fixed; top: 20px; left: 20px;"> <input type="text" name="name" placeholder="Your name"> </form></pre><div class="contentsignin">Copy after login</div></div><p>It should be noted that even if some HTML elements support fixed positioning, there may be compatibility issues in some older versions of browsers. In actual development, it is recommended to use block-level elements such as div as containers, and then perform fixed positioning within them. </p> <p>To sum up, the main reason why fixed positioning is not supported in HTML is that the characteristics of some elements are not suitable for fixed positioning. Inline elements do not occupy an exclusive row, but fixed positioning requires an exclusive row; the special structure of table elements and form elements is not suitable for fixed positioning layouts. In actual development, appropriate elements should be selected for layout according to needs, and elements that do not support fixed positioning should be avoided. </p> <p>I hope that through the analysis and code examples of this article, readers can understand why fixed positioning is not supported in HTML and make reasonable choices in actual development. </p><p>The above is the detailed content of Analysis of the reasons why fixed positioning cannot be used in HTML.

Fixed-positioned elements are positioned relative to the viewport, not relative to their parent elements or other elements, which means This means that fixedly positioned elements will remain in a fixed position in the viewport no matter how the user scrolls the page. Fixed positioning requires attention to compatibility, mobile devices, performance impact, etc. Fixed positioning is widely used in scenarios such as navigation bars, advertising banners, return to top buttons, and floating toolbars.</p> </div> <div class="phphistorical_Version2_mids"> <a href="https://www.php.cn/faq/765392.html" title="How to position elements in css" class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/202404/26/2024042610242114765.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="How to position elements in css" /> </a> <a href="https://www.php.cn/faq/765392.html" title="How to position elements in css" class="phphistorical_Version2_mids_title">How to position elements in css</a> <span class="Articlelist_txts_time">Apr 26, 2024 am 10:24 AM</span> <p class="Articlelist_txts_p">There are four methods of CSS element positioning: static, relative, absolute, and fixed positioning. Static positioning is the default and the element is not affected by positioning rules. Relative positioning moves an element relative to itself without affecting document flow. Absolute positioning removes an element from the document flow and positions it relative to its ancestor elements.
