How to create a responsive login form with CSS?

Different browsers have differences in CSS parsing, resulting in inconsistent display effects, mainly including the default style difference, box model calculation method, Flexbox and Grid layout support level, and inconsistent behavior of certain CSS attributes. 1. The default style processing is inconsistent. The solution is to use CSSReset or Normalize.css to unify the initial style; 2. The box model calculation method of the old version of IE is different. It is recommended to use box-sizing:border-box in a unified manner; 3. Flexbox and Grid perform differently in edge cases or in old versions. More tests and use Autoprefixer; 4. Some CSS attribute behaviors are inconsistent. CanIuse must be consulted and downgraded.

accent-color is an attribute used in CSS to customize the highlight colors of form elements such as checkboxes, radio buttons and sliders; 1. It directly changes the default color of the selected state of the form control, such as changing the blue check mark of the checkbox to red; 2. Supported elements include input boxes of type="checkbox", type="radio" and type="range"; 3. Using accent-color can avoid complex custom styles and extra DOM structures, and maintain native accessibility; 4. It is generally supported by modern browsers, and old browsers need to be downgraded; 5. Set accent-col

Browser default styles ensure basic readability by automatically applying margins, fills, fonts, and form element styles, but can cause inconsistent cross-browser layouts. 1. The default margin and fill change the layout flow, such as the spacing of titles, paragraphs and lists; 2. The default font settings affect readability, such as 16px font size and TimesNewRoman font; 3. The form elements are very different in different browsers, so the appearance needs to be reset; 4. Some tags such as strong and em have default emphasis styles and need to be explicitly overwritten. Workarounds include using Normalize.css, reset styles, or globally clear margins and fills, while customizing fonts and form styles for consistency.

To beautify the beginning of a paragraph to enhance visual appeal, a common practice is to use pseudo-elements of CSS or manually style the document. In web development, p::first-letter can be used to set the first letter style, such as enlarging, bolding, and discoloring, but it should be noted that it is only suitable for block-level elements; if you want to highlight the entire first line, use p::first-line to add styles; in document software such as Word, you can manually adjust the first letter format or create style templates, and InDesign has a built-in "first-sinking" function suitable for publishing and design; when applying, you need to pay attention to details, such as avoiding complex styles affecting reading and ensuring compatibility and format consistency.

CSS' counter-reset and counter-increment are used to automatically number HTML elements. 1. Use counter-reset to initialize or reset the counter, for example, section{counter-reset:sub-section;} to create a counter named sub-section; 2. Increment the counter through counter-increment, such as h3{counter-increment:sub-section;} to increment each h3 title number; 3. Use content attribute to combine pseudo-elements to display the counter, such as h3::before{content:

To change the text color in CSS, you need to use the color attribute; 1. Use the color attribute to set the text foreground color, supporting color names (such as red), hexadecimal codes (such as #ff0000), RGB values (such as rgb(255,0,0)), HSL values (such as hsl(0,100%,50%)), and RGBA or HSLA with transparency (such as rgba(255,0,0,0.5)); 2. You can apply colors to any element containing text, such as h1 to h6 titles, paragraph p, link a (note the color settings of different states of a:link, a:visited, a:hover, a:active), buttons, div, span, etc.; 3.
